Sprockets for dual pitch roller chains can be found in an individual or double-toothed style. Single-toothed sprockets for dual pitch roller chains possess the same behaviour as standard sprockets for roller chains in accordance to ISO 606. Because of the larger chain pitch of dual pitch roller chains you’ll be able to increase strength by toothing modifications.

Double-toothed sprockets are offered either completely or in half tooth steps. Full tooth steps are double-toothed to ensure that only a part of the the teeth is used effectively. The benefit is that when the chain is usually exchanged the up to now unutilised the teeth can be used after that, and the sprockets can stay in the system.
In order to increase the life cycle of a chain drive even more, sprockets can be produced with half tooth steps. With every rotation the chain joints move one tooth forward in the meshing. This reduces the put on 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 made of C 45, stainless steel, and special components with a material strength of between 500 N/mm² and 600 N/mm². Apart from hardened toothing, we also supply surface area 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 on pitch circle
Slot holes on hub and hole circle

Our sprockets for dual pitch roller chains are available in an individual or in a double-toothed version.

Our in-stock standard double pitch sprockets are produced out of SAE-1045 case hardened steel with extra-hardened teeth and coated with black oxide. These sprockets are really durable, high-strength, and produced to high precision tolerances. Stock dual pitch sprockets include standard roller and carrier roller style, single duty sprockets are made to order and typically take from a couple of 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 outside diameter and width as the single-pitch equivalent just with a different tooth profile to allow appropriate seating of the chain. On even tooth-counts, these sprockets just engage with the chain on every other tooth because there are two teeth per pitch. On odd tooth counts, any given tooth is engaged only on 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 seat and build relationships each tooth. These sprockets will have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
One duty sprockets are manufactured to where every single tooth gets engaged evenly on every revolution. This sprocket type has become obsolete generally in most applications but is still available.
When using double pitch roller chain it is highly Double Pitch Chain Sprockets recommended if not required to use a dual pitch sprocket. This is because dual pitch sprockets are produced with a particular tooth profile that allows for the roller to properly seat and engage with one’s teeth of the sprocket. The above picture on the left may be the standard tooth profile and the photo on the right may be the special dual pitch sprocket profile. As you can see above, the dual pitch sprockets tooth profile is somewhat deeper and cut differently to totally accept the double pitch chain roller. If utilizing a standard sprocket, failing to engage will result in chain jumping along with excessive wear. Something important to note is that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is usually 31 or even more you can use a standard roller chain sprocket. This rule does not connect with carrier roller design chains which where the roller diameter exceeds the sidebar elevation, these chain sizes include 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 offers an extended working life at a really great price! 2042A16 double pitch sprockets are produced specifically for C2042 double pitch roller chain, have 16 teeth, and completely meet all ANSI Criteria. Additionally, this sprocket has a share bore but we can 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, heat treated, and is produced using a high quality steel. Carrying out this with a sprocket makes it much more long lasting, perform to its best capabilities, and last a lot longer when compared to competition. Thanks to our sourcing experts, companions, 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 assist you.

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 engage with different teeth every time the rollers rotate (when actual number of teeth 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 amount of teeth. This mechanism allows extension of sprocket existence as less wear and abrasion.
S roller type chain can work well with regular roller chain sprocket with more than 30 teeth.
