Sprockets for dual pitch roller chains are available in an individual or double-toothed design. Single-toothed sprockets for dual pitch roller chains have the same behaviour as standard sprockets for roller chains according to ISO 606. Due to the larger chain pitch of dual pitch roller chains you’ll be able to increase durability by toothing modifications.

Double-toothed sprockets are offered either in full or in two tooth steps. Full tooth techniques are double-toothed so that only part of the teeth is used effectively. The advantage is that whenever the chain can be exchanged the up to now unutilised teeth can be used then, and the sprockets can remain 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 ahead in the meshing. This reduces the use of the chain and the tooth edges. This sort of toothing is often used when, due to the respective design, only minor deflections could be realised.
Our sprockets and plate sprockets are made from C 45, stainless steel, and special components with a material power of between 500 N/mm² and 600 N/mm². Apart from hardened toothing, we also supply surface treated types.
Double pitch roller chains are manufactured 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 can be found in an individual or in a double-toothed version.

Our in-stock standard double pitch sprockets are produced out of SAE-1045 case hardened metal with extra-hardened teeth and coated with black oxide. These sprockets are really durable, high-strength, and manufactured 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 anywhere from a few business days to some weeks to manufacture based on our factory loads and Double Pitch Chain Sprockets china sprocket specifics.
Standard Roller Type
Regular roller type sprockets will be the same outdoors diameter and width as the single-pitch equivalent just with a different tooth profile to allow appropriate seating of the chain. On also tooth-counts, these sprockets just engage with the chain on almost every other tooth because there are two tooth per pitch. On odd tooth counts, any provided tooth is engaged only on almost every other revolution which of training course increases the sprocket life.
Carrier Roller Type
Carrier roller type dual pitch sprockets are cut with space cutters to permit the carrier roller to properly seat and engage with each tooth. These sprockets will have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
Single duty sprockets are manufactured to where every tooth gets involved evenly on each revolution. This sprocket type has become obsolete in most applications but is still available.
When using double pitch roller chain it is extremely recommended if not required to use a dual pitch sprocket. It is because dual pitch sprockets are manufactured with a particular tooth profile which allows for the roller to properly seat and build relationships one’s teeth of the sprocket. The above photo on the left is the standard tooth profile and the picture on the right is the special dual pitch sprocket profile. As you can see above, the double pitch sprockets tooth profile is slightly deeper and cut differently to fully accept the double pitch chain roller. If utilizing a standard sprocket, failure to engage will result in chain jumping and also excessive wear. Something vital that you note can be that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is 31 or more you can make use of a standard 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 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 a long working life at a really great price! 2042A16 dual pitch sprockets are manufactured specifically for C2042 dual pitch roller chain, possess 16 teeth, and fully meet all ANSI Standards. Additionally, this sprocket includes a share 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 is Black Oxide Finished, temperature treated, and is manufactured using a high quality steel. Performing this with a sprocket helps it be much more long lasting, perform to its greatest capabilities, and last much longer compared to the competition. Thanks to our sourcing experts, companions, and engineers, these sprockets are usually in share and at a really great price. For prices and availability please e mail us and we’ll 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 every other tooth. Sprockets will have an extended life as chains engage with different teeth each time the rollers rotate (when actual number of tooth 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 quantity of teeth. This mechanism allows expansion of sprocket existence as less use and abrasion.
S roller type chain can work well with standard roller chain sprocket with more than 30 teeth.
