The chain spocket, as a drive or deflection for chains, has pockets to hold the chain links with a D-profile cross section with flat side surfaces  parallel to the centre plane of the chain links, and outer surfaces at right angles to the chain link centre plane. The chain links are pressed firmly against the outer surfaces and each of the side surfaces by the angled laying surfaces at the base of the pockets, and also the support surfaces of the wheel body together with the end sides of the webs formed by the leading and trailing walls of the pocket.


When fitting new chainwheels it is very important that a new chain is fitted at the same time, and vice versa. Using an old chain with new sprockets, or a new chain with old sprockets will cause rapid wear.

It is important if you are installing the chainwheels yourself to have the factory service manual specific to your model. Our chainwheels are made to be a direct replacement for your OEM chainwheels and as such, the installation should be performed according to your models service manual.

During use a chain will stretch (i.e. the pins will wear causing extension of the chain). Using a chain which has been stretched more than the above maximum allowance causes the chain to ride up the teeth of the sprocket. This causes damage to the tips of the chainwheels teeth, as the force transmitted by the chain is transmitted entirely through the top of the tooth, rather than the whole tooth. This results in severe wearing of the chainwheel.


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

Width (inches)
14 28 25 18

12 48 41 14
12 48 40 516
58 58 50 38
34 68 60 12
1 88 80 58

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.

Problems with sprockets

If you’re having trouble with your HP Sprocket, you’re not alone. This bike component isn’t without issues, but it’s also susceptible to other wear and tear. Check for worn tooth surfaces and hooked tips. When teeth wear out quickly, they can break the chain, so make sure you fix them as soon as possible.
You can solve this issue by installing the latest firmware update for your Sprocket printer. The firmware update is designed to provide a safe and reliable printing experience. When your Sprocket printer doesn’t print the pictures, it is likely because it’s not receiving enough power from the battery. Make sure the battery is at least 25% before you begin.
Insufficient or improper lubrication can cause a variety of problems. Proper lubrication can prevent or remove excessive wear, or protect the chain from the environment. It can also reduce the risk of excessive chain slack. The following are just a few common problems that can cause slack in the chain.
In case of excessive wear, a new sprocket may be necessary. If the sprocket and chain do not match, replace them with a similar size. In addition, a shock absorber can be installed to minimize load. Another alternative is to install a take-up idler, which helps prevent excessive chain elongation.
Improper alignment of the sprocket is another common cause of chain drive problems. If the sprocket is not aligned correctly, it will not be able to move smoothly through the chain during rotation. The teeth of the sprocket will become hooked, preventing the roller from smoothly moving through. This will force the roller chain to cling to the sprocket, and need to be replaced.

Common types of sprockets

Power transmission equipment typically utilizes sprockets and chains. These are used in pairs to provide speed reduction. They are different from gears because the teeth of the sprocket do not mesh with those of the mating gears. They are typically made of plastic, but they can also be made of metal.
There are many common types of sprockets and chains. Some of these types of sprockets have large, narrow, or variable tooth pitch. The size of the sprocket depends on the size and pitch of the chain. If you are using a chain with a large pitch diameter, you should use a sprocket with large teeth. Conversely, a smaller pitch diameter will require a sprocket with small teeth.
Another way to identify the type of sprocket you’re using is to look at the number of strands. Single-strand sprockets are the most common, but you’ll also find many types that have multiple strands of chains. Multi-strand chains are generally larger and allow for greater torque to be transmitted from a common central shaft.
Another type is flat sprockets, which have no hub and drive through a series of holes. They are used for transmission of power or material in chain-driven systems, such as bicycles. They can also be used for overhead conveyors. In some cases, there is a special type that fits the shaft of an automobile, such as a transmission shaft.
There are many different types of sprockets, each with a unique function. Some are used for conveyor chains, while others are used for other applications. In most cases, sprockets are used in chain-driven machinery. They come in different sizes and pitches and are designed to work with particular types of chains.
When choosing a motor or transmission system, it is important to match sprockets and chains. A perfectly matched set of components will ensure that the motor and transmission work together. Generally, this alignment comes down to sprocket-to-sprocket matching. The process involves jacking up the motor and lining up the sprockets and chains. Then, the sprockets and chains are locked into place with cotter pins.

Size of sprockets

To determine the correct chain length and sprocket diameter, the first step is to understand the difference between the diameters of the sprockets and cassettes. The smaller the diameters of sprockets, the lower the chain tension. The larger the sprocket, the longer the chain will need to be. This process requires the use of a derailleur that can roll a larger number of chains.
In addition to chain length, the spacing between sprockets is another important factor. If the sprockets are too far apart, the chain may slip through the sprocket. A smaller range of sprockets will prevent this and will increase the number of discrete gear ratios. In addition, if the chain skips over a sprocket, it will cause discomfort in shifting.
Choosing the correct size of sprockets is essential for cycling. Larger sprockets are usually necessary for road bikes. Likewise, a road bike will have larger gears than a gravel bike. Larger gears will help the cyclist accelerate more smoothly and ensure a smoother ride.
Using a chain calculator can help you determine the proper size of sprockets for your bike. You can also use a chain length calculator to determine the correct chain length. This calculator uses the distance between the sprockets to calculate chain length. However, it is important to note that it is not possible to calculate the length of a chain with a single sprocket.
The size of the sprocket must be in proportion to the length of the chain. It can be controlled by either adjusting the center of the sprocket or moving it to the proper position. The center of rotation of the sprocket is defined by the chosen geometry reference.
The report covers global and regional sales of sprockets. It also contains information on competitive dynamics and market concentration status. Moreover, the report includes detailed information about the manufacturers of sprockets. The study also includes regional and global market forecasts. It also provides a detailed breakdown of sales by type, application, and region.
When choosing the right size of sprockets, remember to take measurements and do some arithmetic. For example, a smaller countershaft sprocket will improve low-speed acceleration, while a larger rear sprocket will improve fuel mileage. In addition, it is recommended that you use the reverse sprocket size if you’re going to be riding on long highways.

Maintenance of sprockets

Proper maintenance of sprockets and chains is crucial to the functioning of your bike. It is important to avoid overstretching them. If this happens, they will not fit properly and will require replacement. It is also important to prevent the kinks in your chain to reduce the amount of stress on your sprockets.
If you are unsure of the state of your sprockets and chains, you can replace them with a new chain and a new sprocket. If you notice that a chain is squeezing between the rear sprocket, it is time to replace the sprocket.
Proper maintenance of sprockets and chains involves cleaning and lubrication. Regular cleaning and lubrication can prevent damage and extend the life cycle of these parts. Proper lubrication will also ensure their smooth operation and minimize the noise. Regardless of whether your sprockets or chains are new or used, lubrication should be carried out at regular intervals to extend their useful life cycle.
Proper alignment of the sprockets and chains will ensure the most efficient performance and reliability. If you regularly change your chain and sprockets, you can prolong the life of these components and avoid costly repairs. Make sure you change the sprockets and chains only with professional mechanics. Always follow the instructions of the motorcycle manufacturer.
Proper maintenance of sprockets and chains is important to prevent premature sprocket replacement. Changing the sprocket too often can result in poor meshing, accelerating wear and tear of the new sprockets. When changing the sprocket, it is essential to turn the worn surface over before you install the new one.
It is important to follow the instructions and warning signs for proper maintenance of sprockets and chains. The safety of the workers and the environment should be prioritized. Follow the instructions of the manufacturer and avoid dangerous situations. It is essential not to anneal or electroplate the chain parts.
Proper lubrication is also vital. Use a non-petroleum based cleaner to clean the chain thoroughly and then apply lubricant. Avoid using engine oil as it is more viscous and cannot protect the chain against water.
