Sprockets for dual pitch roller chains are available in a single or double-toothed design. Single-toothed sprockets for dual 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 you’ll be able to increase sturdiness by toothing modifications.
Double-toothed sprockets can be found either in full or in half tooth steps. Full tooth actions are double-toothed to ensure that only part of the the teeth is used effectively. The benefit is that whenever the chain can be exchanged the so far unutilised 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 ahead in the meshing. This reduces the put on of the chain and the tooth edges. This sort of toothing is often used when, due to the respective Double Pitch Chain Sprockets design, only minor deflections could be realised.
Our sprockets and plate sprockets are made of C 45, stainless, 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 ask for 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 dual pitch roller chains are available in a single or in a double-toothed version.
Our in-stock standard double pitch sprockets are manufactured out of SAE-1045 case hardened metal with extra-hardened teeth and coated with black oxide. These sprockets are extremely durable, high-strength, and produced to high precision tolerances. Stock double pitch sprockets include regular roller and carrier roller style, single duty sprockets are made to order and typically take from a few business days to a few weeks to produce based on our factory loads and sprocket specifics.
Standard Roller Type
Standard roller type sprockets are the same outdoors diameter and width as the single-pitch equivalent simply with a different tooth profile to permit proper 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 only on almost every other revolution which of course increases 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 could have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
One duty sprockets are produced to where every tooth gets engaged evenly on each revolution. This sprocket type has become obsolete in most applications but is still available.
When using dual pitch roller chain it is highly recommended if not required to use a double pitch sprocket. It is because dual pitch sprockets are produced with a special tooth profile which allows for the roller to properly seat and build relationships the teeth of the sprocket. The above picture on the left is the standard tooth profile and the photo on the right is the special double pitch sprocket profile. As you can see above, the dual pitch sprockets tooth profile can be somewhat deeper and cut differently to totally accept the double pitch chain roller. If using a standard sprocket, failure to engage will lead to chain jumping in addition to excessive wear. Something vital that you note is definitely that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is 31 or even more you can make use of a typical roller chain sprocket. This guideline does not apply to carrier roller style chains which where in fact 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
This 2042A16 sprocket is durable, exceeds in quality, and will be offering a long working life at an extremely great price! 2042A16 double pitch sprockets are manufactured specifically for C2042 double pitch roller chain, possess 16 teeth, and fully meet all ANSI Standards. Additionally, this sprocket has a share bore but we are able to supply the sprocket already bored out to nearly every requested bore size. Something that sets this 2042A16 sprocket apart from others is that it’s Black Oxide Finished, temperature treated, and is manufactured using a top quality metal. Performing this with a sprocket helps it be much more long lasting, perform to its greatest capabilities, and last a lot longer compared to the competition. Thanks to our sourcing experts, companions, and engineers, these sprockets are normally in stock and at an extremely great price. For pricing and availability please e mail us and we will be happy to assist you.

Double Pitch Chain Sprockets
Available for Dual 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 build relationships almost every other tooth. Sprockets will have an extended life as chains engage with different teeth every time the rollers rotate (when actual number of teeth is odd).
Sprocket for Double Pitch Chain
As demonstrated in the sketch, chain rollers use different teeth on each time of revolution when each roller skip one tooth and sprocket has odd number of teeth. This mechanism allows extension of sprocket existence as less use and abrasion.
S roller type chain can work well with regular roller chain sprocket with an increase of than 30 teeth.
