Sprockets for dual pitch roller chains are available in an individual or double-toothed style. Single-toothed sprockets for dual pitch roller chains have the same behaviour as regular sprockets for roller chains according to ISO 606. Due to the larger chain pitch of double pitch roller chains it is possible to increase toughness by toothing modifications.
Double-toothed sprockets can be found either completely or in half tooth steps. Full tooth measures are double-toothed to ensure that only part of the teeth is used effectively. The advantage is that when the chain is usually exchanged the up to now unutilised the teeth can be used after that, and the sprockets can remain in the system.
In order to increase 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 forward in the meshing. This decreases the use of the chain and the tooth edges. This type of toothing is frequently used when, because of the respective design, just minor Double Pitch Chain Sprockets china deflections can be realised.
Our sprockets and plate sprockets are made of 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 treated types.
Double pitch roller chains are produced according to the respective order and customers’ specifications.
On request we supply sprockets with:
Bore and grove
Tapped and pin holes for bore
Tapped and pin holes for bore upon pitch circle
Slot holes on hub and hole circle
Our sprockets for double pitch roller chains are available in a single or in a double-toothed version.
Our in-stock standard dual pitch sprockets are produced out of SAE-1045 case hardened steel with extra-hardened teeth and coated with dark oxide. These sprockets are really durable, high-strength, and manufactured to high precision tolerances. Stock dual pitch sprockets include standard roller and carrier roller design, one duty sprockets are made to order and typically take anywhere from a couple of business days to a few weeks to manufacture based on our factory loads and sprocket specifics.
Standard Roller Type
Standard roller type sprockets will be the same outdoors diameter and width as the single-pitch equivalent simply with a different tooth profile to permit correct seating of the chain. On even tooth-counts, these sprockets just build relationships the chain on almost every other tooth because there are two teeth per pitch. On odd tooth counts, any provided tooth is engaged only on almost every other revolution which of course escalates the sprocket life.
Carrier Roller Type
Carrier roller type dual pitch sprockets are cut with space cutters to permit the carrier roller to properly chair and engage with each tooth. These sprockets will have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
Solitary duty sprockets are manufactured to where every tooth gets engaged evenly on each revolution. This sprocket type is becoming obsolete in most applications but continues to be available.
When using double pitch roller chain it is highly recommended if not required to use a dual pitch sprocket. This is because dual pitch sprockets are produced with a special tooth profile that allows for the roller to correctly seat and engage with the teeth of the sprocket. The above picture on the left may be the standard tooth profile and the photo on the right is the special dual pitch sprocket profile. As you can see above, the dual pitch sprockets tooth profile is certainly slightly deeper and cut differently to fully accept the double pitch chain roller. If using a standard sprocket, failure to engage will lead to chain jumping as well as excessive wear. Something important to note is usually that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count can be 31 or even more you can use a standard roller chain sprocket. This guideline does not connect with carrier roller design chains which where in fact the roller diameter exceeds the sidebar height, these chain sizes consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
2042A16 SPROCKET WITH STOCK BORE
This 2042A16 sprocket is durable, exceeds in quality, and will be offering an extended working life at an extremely great price! 2042A16 double pitch sprockets are manufactured specifically for C2042 dual pitch roller chain, possess 16 teeth, and fully meet all ANSI Criteria. Additionally, this sprocket includes a stock bore but we are able to supply the sprocket currently bored out to nearly every requested bore size. A thing that sets this 2042A16 sprocket aside from others is that it’s Black Oxide Finished, heat treated, and is manufactured using a high quality steel. Doing this with a sprocket makes it much more long lasting, perform to its greatest capabilities, and last a lot longer when compared to competition. Thanks to our sourcing experts, partners, and engineers, these sprockets are normally in share and at an extremely great price. For prices and availability please e mail us and we’ll be happy to help you.

Double Pitch Chain Sprockets
Available for Dual 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 make use of S rollers engage with every other tooth. Sprockets could have an extended life as chains engage with different teeth each time the rollers rotate (when actual number of teeth is odd).
Sprocket for Dual Pitch Chain
As shown in the sketch, chain rollers use different teeth on each time of revolution when each roller skip one tooth and sprocket has odd quantity of teeth. This system allows expansion of sprocket lifestyle as less put on and abrasion.
S roller type chain can work well with regular roller chain sprocket with an increase of than 30 teeth.
