Sprockets for dual pitch roller chains can be found in a single or double-toothed design. Single-toothed sprockets for double 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 it is possible to increase durability by toothing modifications.

Double-toothed sprockets are offered either completely or in half tooth steps. Full tooth actions are double-toothed to ensure that only part of the the teeth is used effectively. The advantage is that whenever 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 raise 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 decreases the use of the chain and the tooth edges. This type of toothing is frequently used when, because of the respective design, only minor deflections could be realised.
Our sprockets and plate sprockets are made from C 45, stainless, and special components 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 manufactured according to the particular order and customers’ specifications.
On request we supply sprockets with:
Bore and grove
Double Pitch Chain Sprockets Tapped and pin holes for bore
Tapped and pin holes for bore on pitch circle
Slot holes upon hub and hole circle

Our sprockets for dual 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 dark oxide. These sprockets are extremely durable, high-strength, and produced to high precision tolerances. Stock dual pitch sprockets include standard roller and carrier roller design, one duty sprockets are created 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 will be the same outside diameter and width as the single-pitch equivalent simply with a different tooth profile to allow appropriate seating of the chain. On also tooth-counts, these sprockets only build relationships the chain on almost every other tooth because there are two the teeth 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 allow the carrier roller to properly seat and build relationships each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
Single duty sprockets are produced to where every tooth gets engaged evenly on each revolution. This sprocket type is becoming obsolete generally in most applications but is still available.
When using double pitch roller chain it is extremely recommended if not necessary 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 picture on the left may be the regular tooth profile and the picture on the right is the special dual pitch sprocket profile. As you can plainly see above, the double pitch sprockets tooth profile can be somewhat deeper and cut differently to totally accept the dual pitch chain roller. If utilizing a standard sprocket, failing to engage will result in chain jumping along with 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 definitely 31 or more you can use a standard roller chain sprocket. This guideline does not apply to carrier roller design chains which where 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
2042A16 Sprocket

This 2042A16 sprocket is durable, exceeds in quality, and will be offering an extended working life at an extremely great price! 2042A16 dual pitch sprockets are produced specifically for C2042 double pitch roller chain, have 16 teeth, and fully meet all ANSI Requirements. Additionally, this sprocket has a stock bore but we are able to supply the sprocket currently bored out to almost any 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 high quality steel. Doing this with a sprocket helps it be much more long lasting, perform to its best capabilities, and last much 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 prices and availability please contact 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 almost every other tooth. Sprockets could have a longer life as chains engage with different teeth each time the rollers rotate (when actual number of teeth is odd).
Sprocket for Double Pitch Chain
As proven in the sketch, chain rollers work with different teeth on each time of revolution when each roller skip one tooth and sprocket has odd number of teeth. This mechanism allows expansion 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.
