Sprockets for double pitch roller chains are available in an individual or double-toothed style. 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 larger chain pitch of double pitch roller chains you’ll be able to increase durability by toothing modifications.
Double-toothed sprockets are offered either in full or in half tooth steps. Complete tooth guidelines are double-toothed to ensure that only a part of the tooth is used effectively. The benefit is that whenever the chain is exchanged the so far unutilised the teeth can be used then, and the sprockets can stay in the system.
In order to boost the life cycle of a chain drive even more, sprockets can be produced with fifty percent 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 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 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 area treated types.
Double pitch roller chains are produced according to the particular 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 dual pitch sprockets are Double Pitch Chain Sprockets 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 dual pitch sprockets include standard roller and carrier roller design, solitary duty sprockets are created to order and typically take from a few business days to some weeks to manufacture based on our factory loads and 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 actually tooth-counts, these sprockets only build relationships the chain on every other tooth because there are two teeth per pitch. On odd tooth counts, any provided tooth is engaged just 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 chair and engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
Single duty sprockets are manufactured to where every single tooth gets engaged evenly on each revolution. This sprocket type is becoming obsolete in most applications but is still available.
When using double pitch roller chain it really is extremely recommended if not required to use a dual pitch sprocket. The reason being double 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 photo on the left is the regular tooth profile and the photo on the right may be 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 fully accept the dual pitch chain roller. If utilizing a standard sprocket, failing to engage will lead to chain jumping and also excessive wear. Something important to note can be 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 style 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 a really great price! 2042A16 double pitch sprockets are produced specifically for C2042 double pitch roller chain, have 16 teeth, and completely meet all ANSI Requirements. Additionally, this sprocket has a stock bore but we are able to supply the sprocket already 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 produced using a high quality metal. Carrying out this with a sprocket makes it much more durable, perform to its best capabilities, and last much longer when compared to competition. Because of our sourcing experts, partners, and engineers, these sprockets are usually in stock and at an extremely great price. For pricing and availability please contact us and we’ll be happy to assist you.

Double Pitch Chain Sprockets
Available for Double 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 almost every other tooth. Sprockets could have a longer life as chains build relationships different teeth every time the rollers rotate (when actual number of tooth is odd).
Sprocket for Dual Pitch Chain
As proven in the sketch, chain rollers use different teeth on each time of revolution when each roller skip one tooth and sprocket has odd quantity of teeth. This mechanism allows expansion of sprocket life as less use and abrasion.
S roller type chain could work well with standard roller chain sprocket with more than 30 teeth.
