ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
CONSTRUCTION OF THE CHAIN
Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CZPT which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.
The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
LUBRICATION
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
Many oil-based lubricants attract dirt and other particles, eventually forming an CZPT paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.
VARIANTS DESIGN
Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.
USE

Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CZPT the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CZPT flight, a system known as Thrust vectoring.
WEAR
The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).
With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.
The lengthening due to wear of a chain is calculated by the following formula:
M = the length of a number of links measured
S = the number of links measured
P = Pitch
In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.
CHAIN STRENGTH
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.
The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.
CHAIN STHangZhouRDS
Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):
Pitch (inches) | Pitch expressed in eighths |
ANSI standard chain number |
Width (inches) |
---|---|---|---|
1⁄4 | 2⁄8 | 25 | 1⁄8 |
3⁄8 | 3⁄8 | 35 | 3⁄16 |
1⁄2 | 4⁄8 | 41 | 1⁄4 |
1⁄2 | 4⁄8 | 40 | 5⁄16 |
5⁄8 | 5⁄8 | 50 | 3⁄8 |
3⁄4 | 6⁄8 | 60 | 1⁄2 |
1 | 8⁄8 | 80 | 5⁄8 |
Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

1. Higher Efficiency: Roller chains provide a more efficient power transmission compared to cable or rope systems. They have lower friction losses, resulting in higher energy transfer and reduced power waste.
2. Precise and Reliable Motion: Roller chains offer precise and reliable motion control. They have minimal elongation and provide accurate positioning, making them suitable for applications that require precise speed and position control.
3. Greater Load Capacity: Roller chains have higher load-carrying capacity compared to cables or ropes of the same size. They can handle heavy loads and transmit high torque, making them suitable for applications that require robust power transmission.
4. Flexibility in Design: Roller chains offer flexibility in design and configuration. They can be easily customized to fit specific application requirements, such as different lengths, pitch sizes, and attachment options.
5. Durability and Longevity: Roller chains are known for their durability and long service life. They are constructed with high-quality materials and undergo heat treatment processes to enhance their strength and wear resistance, making them suitable for demanding industrial applications.
6. Maintenance and Replacement: Roller chains are relatively easy to maintain and replace. Lubrication and periodic inspection can help prolong their lifespan, and if a chain does wear out or break, it can be readily replaced with a new one, minimizing downtime.
7. Cost-Effective Solution: Roller chains are often a cost-effective solution for power transmission. They have a lower initial cost compared to some cable or rope systems and offer reliable performance over an extended period, resulting in lower maintenance and replacement costs.
While cable or rope systems have their own advantages in certain applications, roller chains excel in terms of efficiency, load capacity, precision, and durability, making them a popular choice for various industries, including manufacturing, automotive, agriculture, and more.
Can roller chains be used for power transmission in agricultural vehicles?
Yes, roller chains are commonly used for power transmission in agricultural vehicles. These vehicles often require reliable and robust power transmission systems to handle the demanding tasks in agricultural operations. Roller chains offer several advantages that make them suitable for such applications. Here’s a detailed answer to the question:
1. High Strength and Durability: Agricultural vehicles operate in rugged environments and encounter heavy loads. Roller chains are known for their high strength and durability, allowing them to withstand the demanding conditions found in agricultural settings. They can handle the power transmission requirements of vehicles used for tasks like plowing, tilling, harvesting, and hauling.
2. Wide Range of Speeds: Agricultural vehicles often operate at various speeds depending on the task at hand. Roller chains can accommodate a wide range of speeds, allowing them to efficiently transmit power even during speed variations. They can handle both low-speed applications, such as crawling through fields, and higher-speed applications, such as transporting crops.
3. Adaptability to Misalignment: Agricultural vehicles may encounter uneven terrain and experience misalignment between the driving and driven components. Roller chains can tolerate a certain degree of misalignment, allowing them to function effectively even in challenging conditions. However, proper alignment should still be maintained to optimize chain performance and longevity.
4. Resistance to Contaminants: Agricultural environments often involve dust, dirt, and debris. Roller chains are designed to operate in such conditions and have inherent resistance to contaminants. They can continue to function reliably even in dusty or dirty environments, reducing the need for frequent cleaning and maintenance.
5. Easy Installation and Maintenance: Roller chains are relatively simple to install and maintain in agricultural vehicles. They can be easily adjusted for proper tension and replaced when necessary. Routine lubrication and inspection help ensure smooth operation and extend the chain’s lifespan.
It’s important to consider the specific requirements of the agricultural vehicle and select the appropriate roller chain based on factors like load capacity, speed range, and environmental conditions. Regular inspection, lubrication, and proper tensioning are essential to ensure optimal performance and longevity of the roller chain in agricultural applications.
What are the benefits of using a roller chain over a gear drive?
Roller chains offer several advantages over gear drives in various applications. Here’s a detailed answer to the question:
1. Flexibility and Versatility: Roller chains provide greater flexibility and versatility compared to gear drives. They can be easily adjusted and modified to accommodate different shaft distances and angular positions. This flexibility allows for easier customization and adaptation to specific application requirements.
2. Cost-Effectiveness: Roller chains are generally more cost-effective than gear drives. They are simpler in design and construction, resulting in lower manufacturing and maintenance costs. Additionally, roller chains are easier to install, replace, and repair, reducing downtime and associated expenses.
3. Shock Absorption: Roller chains are designed to absorb shock loads and vibrations better than gear drives. The flexibility of the chain links and the ability to rotate on the sprockets allow for better shock absorption, reducing the risk of component failure and increasing overall system durability.
4. High-Speed Capability: Roller chains can handle high-speed applications more effectively than gear drives. They are designed to maintain proper engagement with the sprockets even at high rotational speeds, providing reliable power transmission. Gear drives, on the other hand, may experience issues such as tooth wear and increased noise at high speeds.
5. Lubrication and Maintenance: Roller chains generally require less frequent lubrication compared to gear drives. The rolling action of the chain links distributes the lubricant along the contact surfaces, reducing friction and wear. This results in lower maintenance requirements and increased operational efficiency.
6. Overload Protection: In applications where overload protection is required, roller chains offer an advantage over gear drives. The inherent flexibility of the chain allows for limited slippage or disengagement under excessive loads, protecting the driven machinery from damage. Gear drives, on the other hand, are more prone to sudden failures when subjected to overload conditions.
Overall, roller chains provide a reliable and cost-effective solution for power transmission in various industries. Their flexibility, shock absorption capability, high-speed performance, and ease of maintenance make them a preferred choice over gear drives in many applications.

Different types of drive chains
Drive chains are an important part of many different types of machinery. In this article, we’ll cover a variety of different types, from square links to engineered steel. From there, we’ll discuss different types of chains, such as double and leaf chains. Let’s take a closer look at each one. Once you know what kind of chain you’re looking for, you can make a buying decision. If you’re not sure where to start, read on to learn more about these types of chains, what to look for when choosing, and how to choose the right chain for your specific application.
Engineering Steel Chain
Engineering steel chains are widely used in conveyors, bucket elevators, tensioning links, transmission chains, etc., and have the characteristics of high strength, low friction, and good shock resistance. Early models of these chains were developed for difficult-to-convey applications. They were originally made of all-steel components with flanged rollers made of cast iron. They then increase in size, strength, and spacing in response to the heavy-duty requirements of the industry.
Today, these chains are used in a wide variety of applications, including tough oil drilling operations and forklifts. They offer excellent durability and high power transfer and are available in a variety of materials. They are also ideal for harsh environments such as harsh oil drilling. Their high-strength steel construction means they can handle harsh operating conditions. Their durability is an essential feature of any chain, and CZPT Chains offers a full line of engineered steel chains to meet your exact specifications.
A drive chain made of engineered steel consists of several components: links, pin joints, and sprockets. This allows them to carry heavy loads with minimal stretch. Due to its internal mechanical advantage, the chain runs around the sprockets with almost 100% efficiency. Also, the chain is made of special steel that can withstand certain conditions. They are available in different alloys and grades. If you have any questions, please feel free to contact us.
Roller chain wear is a major problem for conveyor and drive chains. In these cases, the rollers of the chain are more prone to wear than the bushings, so lubrication is essential. Many chains are designed to work with little or no lubrication. Finally, material selection is an important factor in the design of engineered steel conveyor chains. These factors will help ensure that the chain stays in good shape.
Conveyor Chains with Square Links
There are two basic types of conveyor chains. The first is the square chain, commonly used in cranes and hoists. It’s cheap to manufacture but more prone to overload. The second is a chain that uses hook joints or detachable links. These are used for short-term power transmission and have a lubricating effect. Usually, they are made of malleable iron but can be more expensive.
Another type of chain is the removable steel chain. For moderate loads, this is an easy-to-install option. The closed end of the tab should face the sprocket. It is very important to maintain the alignment of the chain relative to the sprockets. The chain should be adjusted to suit the load before installation. It is important to keep the chain lubricated to prolong its life.
Steel chains offer a wider selection of materials and heat treatments. This chain is also more accurate than its counterpart. Steel bushing chains are less expensive but require more frequent lubrication. Steel roller chains are often used for long conveyor centers or high loads. However, lower friction requirements require lower strength chains. This means that chains with square links are a better choice for smaller conveyors. But this style has its drawbacks.
Bushing chains are made of steel and are an excellent alternative for small-scale applications. The pins are silent and prevent tooth damage. Bushed roller chains are also used to a certain extent as conveyor chains. However, the main advantage of the bushing roller chain is that it does not make any noise at all. Bushed roller chains are made of alloy steel and are suitable for very low-speed applications.
double chain
Double-strand roller chain, also known as a double-strand, consists of two rows of single-strand links. It has high impact strength, low weight, and a small form factor. Duplex roller chains are manufactured using CZPT technology, which uses solid rollers to improve sprocket tooth rotation and reduce shock loads. During the manufacturing process, the metal is heat-treated to increase strength and reduce corrosion.
A single chain is designed for a single sprocket, while a double chain consists of two identical chains connected side by side. Double chains are more durable than simple chains because double rollers contain roller bearings, pins, and other components. Simplex drive chains can handle high loads, while duplex drive chains are designed for medium-duty applications.
leaf chain
Blade chains are used in reciprocating devices such as forklifts. They are also used in machine tools for counterweight chains. Leaf chains come in a variety of lengths, usually with female or male ends. Leaf chains can be manufactured in even or odd pitches and are ideal for lifting and balancing. This article will introduce some key uses of leaf chains in drive chains. Additionally, we’ll discuss how they are made and how they behave in applications.
Most drive chains today are made from leaf chains. These chains are designed to increase the strength of the chain. However, they are less expensive than other types of chains. You can also purchase specialized leaf chains for certain applications. CZPT Chain also offers custom leaf chains for your unique needs. Leaf chains are commonly used in forklifts, material handling, and lifting applications. They are usually made from high-quality components. The BL1688 Leaf Chain has 8 x 8 laces and is sold in 10-foot boxes or 25- to 100-foot reels. The leaf chain can be cut as needed.
When selecting a leaf chain for a specific application, consider the minimum tensile strength of the chain. The minimum breaking strength must be high enough to protect the worker or machine, but must also be legal for the type of machine. Most manufacturers publish this minimum strength requirement. To make the most durable leaf chain, design engineers must consider the ISO4347 standard when choosing the right leaf chain. Leaf chain manufacturers tend to exceed international standards by about 20%.
roller chain
Roller chains are made from a variety of materials. Some common materials include steel and stainless steel. The most suitable material depends on cost, environmental conditions, and horsepower transmission design. Chain manufacturers can optimize the material for the intended use. Depending on its size, spacing, and special construction techniques, it can be made lighter or heavier. This is an advantage for applications in noise-sensitive environments. Below are some examples of common uses for roller chains.
The wear of the components in a roller chain is an unavoidable part of its operation. The amount of elongation depends on factors such as lubrication, load, and the frequency of articulation between the pin and bushing. Manufacturing critical wear parts require careful attention to detail. Proper raw materials, manufacturing, and assembly are critical to product performance and longevity. If these components aren’t of high quality, they won’t last as long as the chain should.
The industry recommends measuring the wear elongation of the roller chain to determine when it needs to be replaced. Proper safety procedures must be used to measure chain tension. The tight span of the chain shall be measured by applying the measuring load specified by ANSI. A correctly measured roller chain is safe to use. For motorcycles, the chain is bigger and stronger. Often, toothed belts are replaced by shaft drives because they are less noisy and require less maintenance.
Tensile strength is the most commonly used measurement method for roller chains. This measurement represents the amount of load the chain can withstand before it breaks. Fatigue strength is another measure of durability. Fatigue strength measures how long a roller chain can withstand long-term use before failing. These two measurements are closely related and maybe the same or different. In addition to tensile strength, fatigue strength is a useful factor to consider when purchasing a chain.

Before choosing the right roller chain for your machine, it is necessary to learn some basics. Learn about sprockets, tensile strength, pitch, and width. Read this article to learn more. It will help you make an informed decision. Getting the right product is critical, but it’s not always as simple as choosing a brand name. You need to choose a company that supports its products and provides good service.
Roller sprocket
If you are planning to purchase roller sprockets for your application, you should first look at the various types available. Sprockets available for single-strand roller chains are manufactured by Boston Steel – Type B sprockets are drilled to size. They are available in 1/4, 3/8, 1/2, 5/8, 3/4 and 1″ pitch sizes.
The diameter of the sprocket is important when choosing the right sprocket for your application. Using a caliper to measure the diameter of a toothless plate is a good way to determine the exact size of the sprocket. A caliper is the diameter of a plate without teeth. On Type B and C sprockets, the hub diameter measures the thickness of the hub.
Another type of sprocket is the steel split sprocket, which is split in diameter. This type is easy to install and remove, and is held together by bolts in the hub. Typically, split sprockets have chain pitches ranging from 40 to 240 and bores ranging from 3/4″ to 6″. The split sprockets are designed with one pointing towards the ceiling and the other two parallel to the floor.
When shopping for sprockets, it is important to remember that they are designed specifically for a specific chain. All chains are manufactured to specific standards. In the United States, the most common standard is ANSI. The chain pitch is the distance between the center of each pin and the center of the next pin. In the US, the standard is always measured in eight-inch intervals.
In addition to sprocket size, sprocket pitch and the surface area also affect chain life. Unlike belt sprockets, which are made of forged steel, the teeth on roller sprockets are stamped from steel sheet or pressed from powdered metal. The harder the teeth, the longer the chain will last.
Roller chain pitch
The pitch of a roller chain is the distance between the sprocket and the pin. The smaller the thread pitch, the smaller the bushing wear. Generally speaking, the smaller the pitch, the longer the life of the chain. For best performance and longest life, manufacturers recommend a minimum chain pitch of 2% to 3%. Chain pitch is important to ensure proper performance, and the manufacturer recommends that you replace the chain when it reaches 2% to 3% of normal.
To determine the correct chain pitch for a particular chain, first determine the sprocket size and pitch. Pitch is the distance between pin centers, measured in 1/8 inch increments. The pin diameter of the chain is also important. If you’re not sure about the pin diameter of your chain, measure a few links to get a good average reading. Alternatively, use a caliper to measure the inside diameter of the sprocket and count the number of teeth.
When sizing a sprocket, measure the chain between the gears with a caliper and compare it to the measurements on the chain size chart. Make sure you have checked all the specs and checked the correct chain pitch. Then, choose the correct chain pitch for your needs. This is a critical step in choosing the right chain. So get the correct pitch for your roller chain. Correct pitch helps ensure maximum performance and safety.
To identify a specific type of roller chain, measure its tensile strength. This represents the amount of load the chain can withstand before breaking. Another key parameter to consider is fatigue strength. Chains with high fatigue strength are more resistant to rust and wear than chains with low fatigue strength. The numbers on the right in the standard numbering represent normal or light duty chains, while the numbers on the left represent the pitch of heavy-duty chains.
Double pitch roller chains are a variant of single pitch chains. They are manufactured according to ISO 606 and meet the same standards as single pitch chains. They are mainly used in applications with lower requirements for speed and power transmission. The plates of double pitch roller chains are also longer than single pitch chains. The double pitch drive series is also used for elevator and long conveyor drives. There are three main types of roller chains: single-pitch chains, double-pitch carriers, and oversized rollers.
Roller chain width
When buying a roller chain, one of the first decisions you must make is its width. To make this determination, you need to measure the overall width of the chain, the diameter, and the width of each roller. You must also know the height and thickness of the board. After taking these measurements, you can start shopping for the perfect roller chain. But before you buy a new chain, it’s important to know what to expect from the chain itself.
There are many different types of roller chains. These chains are available for ANSI and metric measurements. They come in single-stranded and double-stranded variants. They are usually used for power transmission. Other types include agricultural, automotive, conveyor, multi-strand, and four-strand chains. These charts also include a chart so you can easily see the exact size you need. Listed below are some of the benefits of buying a roller chain.
Roller diameter and pin diameter are important factors in choosing the correct chain width. The width of the chain is the nearest binary fraction of 5/8 of an inch. It should be at least half the thickness of the sprocket, and the plate thickness is one-eighth the width of the chain. Overweight chains are indicated with the suffix H. The pitch and width of the chain are determined by the working load and machine speed.
The outer links of the roller chain are called pin links. These pins are inserted into the bushings of the adjacent roller links. They are held in place by cotter pins. Pin links are usually pressed into the pins of heavy-duty chains. These pins are used to hold the rollers in place. However, these pin chains can reduce the power rating of roller chains by up to 20%.
The ANSI 29.1 Steel Chain Specification specifies a minimum pitch in inches and ultimate strength of 12,500 x pitch in inches. At the same time, the O-ring chain greatly reduces wear due to its lubricating effect. O-ring and X-ring chains contain a lubricant injected by vacuum when riveting the chain together. Transmission chains are tested and governed by standards bodies such as ANSI. In 2011, the American Society of Mechanical Engineers developed a standard for precision power transmission chains.
Roller chain tensile strength
One of the most important indicators of roller chain strength is tensile strength. This measurement refers to the amount of load the chain can withstand before breaking. Another measure, called fatigue strength, refers to the maximum load a chain can withstand before it breaks. The strength of a roller chain depends on its size, the quality of the steel used in its construction, and the heat treatment. There are also differences in the types of shot peening used to treat steel, pitch holes, and link plates.
When choosing a roller chain, the workload is critical. This is the maximum load the chain can withstand before fatigue failure occurs. This measurement is critical because it helps determine the type of load applied to the chain. When deciding which roller chain to buy, be sure to consider the mechanical type and desired strength. Then, make sure it meets strength and load-carrying capacity requirements.
The ultimate tensile strength of a roller chain is based on the manufacturer’s recommended maximum tensile strength. However, the actual tensile strength may be higher or lower than this value. The working load limit of a roller chain can also be calculated by multiplying the chain diameter by the grade. The working load limit of a chain is the highest tension it can withstand before breaking. This value is usually expressed in points.
The maximum tensile strength of roller chains varies by chain type. The single-strand heavy chain has thick side plates for higher shock loads. Single strand heavy-duty roller chains, also known as “bushing” roller chains, are also available. Double-stranded heavy chains are structurally similar, but they have two layers of steel connected by pins that are nearly twice as strong as standard roller chains.
The tensile strength of a single-strand roller chain is approximately 500 tons. In comparison, a single-chain blockchain has a tensile strength of 900. The tensile strength of the two is similar, and it is not recommended to choose one or the other. Although steel and titanium chains are considered the strongest materials for roller chains, these materials are not magnetic.

Pin chain conveyor
The choice between roller chains and friction drives depends on the usage environment. Roller chains are more resistant to dirty environments and are more suitable for conveying bulk products. The pivot chain is designed to handle highly bulk products. Ideally, the center-to-center distance between the two axles should be thirty to fifty times the chain pitch. The size of the sprocket will depend on the usage environment, which will also determine the fatigue strength and resistance of the chain.
Roller chains are more resistant to dirty environments
There are some key differences between drive chains and roller chains. The most notable difference is in the materials. Drive chains are generally more durable than roller chains. However, both chains are prone to dirty environments. While solution chains are sometimes used for heavy-duty tasks, roller chains are often used in dirtier environments. In fact, drive chains are often used when the job is very dirty and the chain has to slide on the rails.
The new lubricant used on the roller chain attracts dirt and other debris to the surface of the chain and prevents lubricant from entering the load-carrying parts of the chain, such as hinge plates, bushings, and rollers. When dust is drawn into these components, lubricants, and dirt form an abrasive paste that accelerates wear.
Lube-free roller chains keep chains clean longer. This makes it easier to specify and install in areas with strict hygiene requirements. CZPT lube-free roller chains meet NSF-H1 lubrication standards. However, lubricated roller chains are still suitable for areas where food contact is unlikely.
Stainless steel roller chains are particularly resistant to acids, alkalis, and low-temperature environments. Since stainless steel is softer than carbon steel, lubricants are not as effective at preventing dirt from entering the chain. Stainless steel roller chains have a higher strength rating than standard chains, but are not as strong as chains made from carbon steel. If you are using a roller chain in a very dirty environment, you should use a stainless steel chain.
A stud chain is more efficient than a friction drive
The present invention relates to a light-duty double-ended chain that is more efficient than conventional chains. Stud chains are made by die-forging bar steel into roughly the-shaped links. This method avoids loss of shear strength due to bending and also minimizes the welded portion. The double-headed chain is light in weight and has strong resistance to fatigue damage.
This chain type has a stud-style design. Stud-shaped design provides greater tensile strength and prevents tangling. Each stud is formed by die forging and is usually shaped like an e or th. However, it is not necessary for each stud to have a uniform cross-sectional shape. Different cross-sectional shapes can be used depending on the application.
Stud chains are more efficient than friction drives because the studs in the chain are integrated. Stud links resist large breaks. Its applications are in conveyor chains and fisheries. Wear tested on boat chains made of SBC material. In the process, bolt chains were found to be more efficient than friction drives. Its applications are rapidly expanding.
Double-ended chains are more efficient for high-load applications. It features studs throughout its internal width to prevent kinking. Chains of this type are commonly used for heavy lifting machinery. Other types of chains are roller chains, power transmission chains, and bushing roller chains. These types of chains are also widely used in motorcycle, bicycle and transportation applications. In addition to being more efficient, stud chains also have fewer wear problems than friction drive chains.
A study on the difference between wear percentage and friction time showed that stud chains are more efficient than friction drives. The friction strips were measured at the beginning of the test. Take it off after 6 hours, 10080 times, and take pictures with the same diameter. As a boundary value, the diameter of the friction strip is smaller than that of a conventional chain. This shows that the present invention has better wear resistance than friction drives.
Shaft chains designed for conveying bulk products
Pivot chains are versatile conveyors used in many applications. Low back type, small backrest distance, rear opening design to prevent the product from sticking to the joints and causing stiffness. Stainless steel and carbon bushing pin chains do not have pre-rotating rollers. In contrast, bucket elevators do not use pivot chains.
CZPT pin chains provide unmatched performance in agricultural and industrial machinery. They are constructed from a single cast barrel and are connected by hardened steel pins. CZPT’s steel pivot chains are strong enough to withstand the corrosive environments of agricultural and industrial applications. The steel pins in the CZPT Pintle Chain are hardened and riveted to ensure long-term durability and optimum performance.
