Sprockets for double pitch roller chains are available in a single or double-toothed design. Single-toothed sprockets for dual pitch roller chains have the same behaviour as standard sprockets for roller chains in accordance to ISO 606. Due to the bigger chain pitch of double pitch roller chains it is possible to increase sturdiness by toothing modifications.
Double-toothed sprockets are offered either completely or in half tooth steps. Full tooth measures are double-toothed to ensure that only a part of the tooth 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 increase the life cycle of a chain drive a lot more, sprockets can be manufactured with half tooth steps. With every rotation the chain joints move one tooth forward in the meshing. This reduces the wear of the chain and the tooth edges. This type of toothing is often used when, due to the respective 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 treated types.
Double pitch roller chains are manufactured 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 on pitch circle
Slot holes on hub and hole circle
Our sprockets for double pitch roller chains are available in an individual or in a double-toothed version.
Our in-stock standard dual pitch sprockets are produced 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 double pitch sprockets include standard roller and carrier roller style, single duty sprockets are made to order and typically take anywhere from a couple of business days to some weeks to produce based on our Double Pitch Chain Sprockets factory loads and sprocket specifics.
Standard Roller Type
Regular roller type sprockets will be the same outside diameter and width as the single-pitch equivalent just with a different tooth profile to permit correct seating of the chain. On also tooth-counts, these sprockets only engage with the chain on almost every other tooth because there are two the teeth per pitch. On odd tooth counts, any provided tooth is engaged just on every other revolution which of course escalates the sprocket life.
Carrier Roller Type
Carrier roller type dual pitch sprockets are cut with space cutters to permit 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 manufactured to where every single tooth gets engaged evenly on each revolution. This sprocket type has become obsolete in most applications but continues to be available.
When using double pitch roller chain it really is highly recommended if not required to use a dual pitch sprocket. It is because double pitch sprockets are produced with a particular tooth profile that allows for the roller to correctly seat and build relationships one’s teeth of the sprocket. The above picture on the left is the standard tooth profile and the picture on the right is the special double pitch sprocket profile. As possible plainly see above, the double pitch sprockets tooth profile is definitely slightly deeper and cut differently to fully accept the dual pitch chain roller. If utilizing a standard sprocket, failing to engage will result in chain jumping in addition to excessive wear. Something vital that you note is 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 rule does not apply to carrier roller design chains which where the roller diameter exceeds the sidebar height, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
2042A16 SPROCKET WITH STOCK BORE
This 2042A16 sprocket is durable, exceeds in quality, and offers a long working life at an extremely great price! 2042A16 double pitch sprockets are produced specifically for C2042 dual pitch roller chain, have 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 apart from others is that it’s Black Oxide Finished, heat treated, and is manufactured using a high quality metal. Carrying out this with a sprocket helps it be much more long lasting, perform to its best capabilities, and last much longer compared to the competition. Thanks to our sourcing experts, companions, and engineers, these sprockets are usually in stock and at an extremely great price. For prices and availability please contact us and we will 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 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 Double Pitch Chain
As demonstrated in the sketch, chain rollers use different teeth on every time of revolution when each roller skip one tooth and sprocket has odd number of teeth. This mechanism allows extension of sprocket lifestyle as less put on and abrasion.
S roller type chain can work well with standard roller chain sprocket with more than 30 teeth.
