Double Pitch Chain Sprockets

Sprockets for double 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 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 strength by toothing modifications.

Double-toothed sprockets are offered either completely or in half tooth steps. Full tooth steps are double-toothed so that only part of the the teeth is used effectively. The advantage is that when the chain is usually 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 even more, sprockets can be manufactured 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 sort of toothing is frequently used when, because of the respective design, just minor deflections could be realised.
Our sprockets and plate sprockets are constructed with 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.
Dual pitch roller chains are produced according to the respective order and customers’ specifications.
On demand 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 can be found in a single 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 black oxide. These sprockets are really durable, high-strength, and produced to high precision tolerances. Stock dual pitch sprockets include regular roller and carrier roller style, solitary duty sprockets are created to order and typically take from a few business days to some weeks to produce based upon 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 even tooth-counts, these sprockets only build relationships the chain on every other tooth because there are two the teeth per pitch. On odd tooth counts, any given tooth is engaged only on every other revolution which of program escalates the sprocket life.
Carrier Roller Type
Carrier roller type double pitch sprockets are cut with space cutters to permit the carrier roller to properly seat and build relationships each tooth. These sprockets will have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
One duty sprockets are produced to where every single tooth gets engaged evenly on each revolution. This sprocket type has become obsolete in most applications but is still available.
When using dual pitch roller chain it really is extremely recommended if not necessary to use a double pitch sprocket. The reason being double pitch sprockets are manufactured with a special tooth profile that allows for the roller to correctly 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 is the special double pitch sprocket profile. As you can see above, the dual pitch sprockets tooth profile is usually slightly deeper and cut differently to fully accept the dual pitch chain roller. If using a standard sprocket, failing to engage will lead to chain jumping as well as excessive wear. Something vital that you note is usually 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 standard roller chain sprocket. This rule does not apply to carrier roller style chains which where 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 will be Double Pitch Chain Sprockets offering an extended working life at an extremely great price! 2042A16 double pitch sprockets are manufactured specifically for C2042 double pitch roller chain, possess 16 teeth, and completely meet all ANSI Criteria. Additionally, this sprocket has a stock bore but we are able to supply the sprocket currently bored out to almost any requested bore size. A thing that sets this 2042A16 sprocket apart from others is that it’s Black Oxide Finished, temperature treated, and is manufactured using a top quality metal. Performing this with a sprocket helps it be much more durable, perform to its best capabilities, and last much longer when compared to competition. Thanks to our sourcing experts, partners, and engineers, these sprockets are normally in share and at an extremely great price.

Double Pitch Chain Sprockets
Available for Double 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 an extended 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 work with 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 life as less wear and abrasion.
S roller type chain could work well with standard roller chain sprocket with an increase of than 30 teeth.
