Sprockets for dual pitch roller chains can be found in an individual or double-toothed design. Single-toothed sprockets for dual pitch roller chains have the same behaviour as regular sprockets for roller chains in accordance to ISO 606. Because of the bigger chain pitch of dual pitch roller chains you’ll be able to increase durability by toothing modifications.
Double-toothed sprockets can be found either completely or in two tooth steps. Full tooth steps are double-toothed so that only part of the tooth is used effectively. The advantage is that when the chain can be exchanged the up to now unutilised the teeth can be used then, and the sprockets can remain in the system.
In order to boost the life cycle of a chain drive a lot more, sprockets can be produced with half tooth steps. With every rotation the chain joints move one tooth forward in the meshing. This decreases the wear of the chain and the tooth edges. This sort of toothing is frequently used when, due to the respective design, just minor deflections can be realised.
Our sprockets and plate sprockets are made of C 45, stainless steel, 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.
Dual pitch roller chains are produced according to the particular 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 on pitch circle
Slot holes on hub and hole circle
Our sprockets for double pitch roller chains can be found in an individual or in a double-toothed version.
Our in-stock standard dual 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, one duty sprockets are made to purchase and typically take from a few business days to some weeks to produce based upon our factory loads and sprocket specifics.
Standard Roller Type
Regular roller type sprockets are the same outdoors Double Pitch Chain Sprockets china diameter and width as the single-pitch equivalent simply with a different tooth profile to allow correct seating of the chain. On even tooth-counts, these sprockets only engage with the chain on every other tooth because there are two the teeth per pitch. On odd tooth counts, any given tooth is engaged just on almost every other revolution which of program 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 chair and engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
Single duty sprockets are produced to where every single tooth gets engaged evenly on every revolution. This sprocket type is becoming obsolete generally 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. The reason being double pitch sprockets are manufactured with a particular tooth profile that allows for the roller to properly seat and engage with the teeth of the sprocket. The above picture on the left is the regular tooth profile and the photo on the right may be the special dual pitch sprocket profile. As you can see above, the double pitch sprockets tooth profile can be slightly deeper and cut differently to fully accept the dual pitch chain roller. If utilizing a standard sprocket, failure to engage will lead to chain jumping as well as excessive wear. Something important to note is definitely 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 make use of a typical roller chain sprocket. This rule does not connect with carrier roller style 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 offers an extended working life at a really great price! 2042A16 dual pitch sprockets are produced specifically for C2042 dual pitch roller chain, possess 16 teeth, and completely meet all ANSI Standards. Additionally, this sprocket has a share bore but we are able to supply the sprocket currently bored out to nearly every requested bore size. Something that sets this 2042A16 sprocket apart from others is that it’s Black Oxide Finished, high temperature treated, and is produced using a top 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. Because of our sourcing experts, partners, and engineers, these sprockets are normally in share and at an extremely great price. For pricing and availability please contact us and we’ll be happy to help you.

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