Double Pitch Chain Sprockets

Sprockets for double pitch roller chains are available in an individual or double-toothed style. Single-toothed sprockets for dual pitch roller chains possess the same behaviour as regular 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 can be found either completely or in two tooth steps. Complete tooth actions are double-toothed so that only a part of the teeth is used effectively. The benefit is that whenever the chain is exchanged the up to now unutilised the teeth can be used then, and the sprockets can remain in the system.
In order to boost 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 forward in the meshing. This reduces the wear of the chain and the tooth edges. This sort of toothing is often used when, because of the respective design, just minor deflections could be realised.
Our sprockets and plate sprockets are made of C 45, stainless, 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 produced according to the respective 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 on pitch circle
Slot holes on hub and hole circle

Our sprockets for dual pitch roller chains can be found in a single 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 dual pitch sprockets include standard roller and carrier roller style, solitary duty sprockets are made to purchase and typically take anywhere from a few business days to a few weeks to manufacture based on our 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 simply with a different tooth profile to permit proper seating of the chain. On even tooth-counts, these sprockets only engage with the chain on 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 seat and engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
One duty sprockets are produced to where every tooth gets engaged evenly on every revolution. This sprocket type has become obsolete generally in most applications but is still available.
When using dual pitch roller chain it really is highly recommended if not necessary to use a double pitch sprocket. This is because double pitch sprockets are manufactured with a particular tooth profile that allows for the roller to properly seat and build relationships the teeth of the sprocket. The above picture on the left may be the standard tooth profile and the photo on the right is the special dual pitch sprocket profile. As you can plainly see above, the dual pitch sprockets tooth profile is definitely somewhat deeper and cut differently to fully accept the double pitch chain roller. If utilizing a standard sprocket, failing to engage will lead to chain jumping and also excessive wear. Something important to note is that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and Double Pitch Chain Sprockets C2160H when the tooth count is 31 or more you can make use of a standard 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
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 Requirements. Additionally, this sprocket has a stock bore but we can supply the sprocket currently bored out to almost any requested bore size. Something that sets this 2042A16 sprocket aside from others is that it’s Black Oxide Finished, temperature treated, and is produced using a top quality steel. Carrying out this with a sprocket makes it much more long lasting, perform to its best capabilities, and last much longer compared to the competition. Thanks to our sourcing experts, partners, and engineers, these sprockets are normally in stock and at an extremely great price. For prices and availability please e mail us and we’ll be happy to help you.

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 build relationships almost every other tooth. Sprockets will have a longer life as chains build relationships different teeth each time the rollers rotate (when actual number of tooth is odd).
Sprocket for Dual Pitch Chain
As shown 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 extension of sprocket existence as less put on and abrasion.
S roller type chain can work well with standard roller chain sprocket with more than 30 teeth.
