Sprockets for dual pitch roller chains can be found in a single or double-toothed design. Single-toothed sprockets for double pitch roller chains possess the same behaviour as standard sprockets for roller chains according to ISO 606. Because of the larger chain pitch of double pitch roller chains it is possible to increase sturdiness by toothing modifications.

Double-toothed sprockets are offered either in full or in half tooth steps. Complete tooth actions are double-toothed so that only part of the tooth is used effectively. The advantage is that whenever the chain is certainly exchanged the so far unutilised the teeth can be used then, and the sprockets can stay in the system.
In order to raise the life cycle of a chain drive even more, sprockets can be manufactured with half tooth steps. With every rotation the chain joints move one tooth ahead in the meshing. This reduces the wear of the chain and the tooth edges. This sort of toothing is often used when, because of the respective design, just minor deflections could be realised.
Our sprockets and plate sprockets are constructed with C 45, stainless, and special materials with a material power of between 500 N/mm² and 600 N/mm². Aside from hardened toothing, we also supply surface area treated types.
Double pitch roller chains are produced according to the particular order and customers’ specifications.
On demand we supply sprockets with:
Bore and grove
Tapped and pin holes for bore
Tapped and pin holes for bore on pitch circle
Slot holes upon hub and hole circle

Our sprockets for dual pitch roller chains can be found in an individual or in a double-toothed version.

Our in-stock standard double pitch sprockets are manufactured out of SAE-1045 case hardened steel with extra-hardened teeth and coated with black oxide. These sprockets are extremely durable, high-strength, and manufactured to high precision tolerances. Stock double pitch sprockets include standard roller and carrier roller design, single duty sprockets are made to order and typically take anywhere from a few business days to a few weeks to produce based upon our factory loads and sprocket specifics.
Standard Roller Type
Regular roller type sprockets will be the same outside diameter and width as the single-pitch equivalent just with a different tooth profile to permit proper seating of the chain. On actually tooth-counts, these sprockets just build relationships the chain on every other tooth because there are two tooth per pitch. On odd tooth counts, any given tooth is engaged just on every other revolution which of training course escalates the sprocket life.
Carrier Roller Type
Carrier roller type double pitch sprockets are cut with space cutters to allow the carrier roller to properly seat and engage with each tooth. These sprockets will have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
Single duty sprockets are manufactured to where every tooth gets involved evenly on every revolution. This sprocket type has become obsolete in most applications but continues to be available.
When using dual pitch roller chain it really is extremely recommended if not required to use a dual pitch sprocket. The reason being dual pitch sprockets are produced with a special tooth profile that allows for the roller to correctly seat and build relationships one’s teeth of the sprocket. The above picture on the left is the standard tooth profile and the picture on the right may be the special dual pitch sprocket profile. As possible plainly see above, the dual pitch sprockets tooth profile is certainly slightly deeper and cut differently to fully accept the dual pitch chain roller. If using a standard sprocket, failure to engage will result in chain jumping along with excessive wear. Something vital that you note can be that with chain sizes C2040, C2050, C2060, C2060H, C2080H, Double Pitch Chain Sprockets C2100H, C2120H, and C2160H when the tooth count can be 31 or more you can use a standard roller chain sprocket. This guideline does not connect with carrier roller design chains which where the roller diameter exceeds the sidebar elevation, these chain sizes consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
2042A16 SPROCKET WITH STOCK BORE
2042A16 Sprocket

This 2042A16 sprocket is durable, exceeds in quality, and will be offering an extended working life at an extremely great price! 2042A16 dual pitch sprockets are manufactured specifically for C2042 double pitch roller chain, possess 16 teeth, and completely meet all ANSI Standards. Additionally, this sprocket includes a stock bore but we are able to supply the sprocket already bored out to nearly every requested bore size. Something that sets this 2042A16 sprocket aside from others is that it’s Black Oxide Finished, temperature treated, and is manufactured using a top quality steel. Carrying out this with a sprocket makes it much more durable, perform to its best capabilities, and last much longer when compared to competition. Because of our sourcing experts, partners, and engineers, these sprockets are normally in stock and at an extremely great price. For prices and availability please contact us and we will be happy to help you.

Extremely Durable
High Quality Sprocket
Double Pitch Chain Sprockets
Available for Double Pitch Chain with S or R rollers.
We offer a line-up for RS2040 – RF2160 with S rollers, and RF2040 – RF2100 with R rollers.
Chains that use S rollers build relationships almost every other tooth. Sprockets could have an extended life as chains build relationships different teeth each time the rollers rotate (when actual number of the teeth is odd).
Sprocket for Dual Pitch Chain
As shown in the sketch, chain rollers use different teeth on every time of revolution when each roller skip one tooth and sprocket has odd amount of teeth. This system allows expansion of sprocket lifestyle as less wear and abrasion.
S roller type chain could work well with standard roller chain sprocket with more than 30 teeth.
