Sprockets for double pitch roller chains are available in a single or double-toothed design. Single-toothed sprockets for double pitch roller chains have the same behaviour as regular sprockets for roller chains according to ISO 606. Because of the bigger chain pitch of dual pitch roller chains it is possible to increase toughness by toothing modifications.

Double-toothed sprockets can be found either in full or in two tooth steps. Complete tooth methods are double-toothed so that only a part of the the teeth is used effectively. The advantage is that whenever the chain is 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 produced with half tooth steps. With every rotation the chain joints move one tooth ahead in the meshing. This decreases the put on of the chain and the tooth edges. This kind of toothing is often used when, because of the respective design, only minor deflections could be realised.
Our sprockets and plate sprockets are made of 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 particular 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 upon 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 metal with extra-hardened teeth and coated with dark oxide. These sprockets are really durable, high-strength, and produced to high precision tolerances. Stock double pitch sprockets include regular roller and carrier roller style, solitary duty sprockets are made to purchase and typically take from a couple of business days to some weeks to manufacture based upon our factory loads and sprocket specifics.
Standard Roller Type
Standard roller type sprockets will be the same outdoors 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 just 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 only on almost every other revolution which of 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 chair and engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
Solitary duty sprockets are produced 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 recommended if not necessary to use a dual pitch sprocket. This is because double pitch sprockets are manufactured with a particular tooth profile which allows for the roller to properly seat and engage with one’s teeth of the sprocket. The above photo on the left is the standard tooth profile and the photo on the right may be the special double pitch sprocket profile. As you can see above, the double pitch sprockets tooth profile is somewhat deeper and cut differently to totally accept the dual pitch chain roller. If using a standard sprocket, failing to engage will lead to chain jumping in addition to 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 certainly 31 or more you can make use of a typical 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 consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
Double Pitch Chain Sprockets 2042A16 SPROCKET WITH STOCK BORE
2042A16 Sprocket

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 Specifications. Additionally, this sprocket has a stock bore but we can supply the sprocket currently bored out to nearly every requested bore size. Something that sets this 2042A16 sprocket aside from others is that it is Black Oxide Finished, high temperature treated, and is manufactured using a top quality steel. Doing this with a sprocket makes it much more durable, perform to its best capabilities, and last a lot longer when compared to competition. Thanks to our sourcing experts, partners, and engineers, these sprockets are normally in share and at a really great price. For prices and availability please contact 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 make use of S rollers engage with every other tooth. Sprockets will 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 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 regular roller chain sprocket with an increase of than 30 teeth.
