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 standard sprockets for roller chains in accordance to ISO 606. Due to the bigger chain pitch of dual pitch roller chains you’ll be able to increase strength by toothing modifications.

Double-toothed sprockets are offered either in full or in two tooth steps. Complete tooth techniques are double-toothed so that only a part of the tooth is used effectively. The benefit is that whenever the chain can be exchanged the up to now unutilised teeth can be used after that, and the sprockets can stay in the system.
In order to boost 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 reduces the wear of the chain and the tooth edges. This sort of toothing is often used when, due to the respective design, only minor deflections can be realised.
Our sprockets and plate sprockets are made from C 45, stainless steel, and special components with a material strength of Double Pitch Chain Sprockets china between 500 N/mm² and 600 N/mm². Aside from hardened toothing, we also supply surface area treated types.
Dual pitch roller chains are manufactured 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 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 double pitch sprockets are manufactured out of SAE-1045 case hardened metal with extra-hardened teeth and coated with dark oxide. These sprockets are extremely durable, high-strength, and manufactured to high precision tolerances. Stock double pitch sprockets include standard roller and carrier roller style, single duty sprockets are created to purchase and typically take anywhere 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 are the same outside diameter and width as the single-pitch equivalent just with a different tooth profile to allow proper seating of the chain. On actually tooth-counts, these sprockets only engage with the chain on every other tooth because there are two tooth per pitch. On odd tooth counts, any given tooth is engaged just 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 allow the carrier roller to properly chair and build relationships each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
One duty sprockets are produced to where every single tooth gets engaged evenly on every 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. It is because double pitch sprockets are produced 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 is the regular tooth profile and the picture on the right may be the special double pitch sprocket profile. As you can see above, the double pitch sprockets tooth profile is usually somewhat 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 along with excessive wear. Something vital that you note can be that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is 31 or even more you can use a typical 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 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 offers a long working life at a really great price! 2042A16 dual 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 share bore but we can supply the sprocket currently bored out to almost any requested bore size. Something that sets this 2042A16 sprocket apart from others is that it is Black Oxide Finished, temperature treated, and is produced using a top quality steel. Carrying out 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, companions, and engineers, these sprockets are usually in stock and at an extremely great price. For prices 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 use S rollers build relationships almost every other tooth. Sprockets will have a longer life as chains build relationships different teeth every 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 each time of revolution when each roller skip one tooth and sprocket has odd amount of teeth. This mechanism allows extension of sprocket existence as less wear and abrasion.
S roller type chain can work well with standard roller chain sprocket with more than 30 teeth.
