Double Pitch Chain Sprockets

Sprockets for dual pitch roller chains are available in a single or double-toothed style. Single-toothed sprockets for double pitch roller chains possess the same behaviour as standard sprockets for roller chains according to ISO 606. Due to the larger chain pitch of dual pitch roller chains you’ll be able to increase strength by toothing modifications.

Double-toothed sprockets are offered either completely or in two tooth steps. Full tooth steps are double-toothed so that only part of the tooth is used effectively. The benefit is that whenever the chain is usually exchanged the up to now unutilised teeth can be used then, and the sprockets can stay in the system.
In order to increase 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 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, and special components with a material strength of between 500 N/mm² and 600 N/mm². Aside from hardened toothing, we also supply surface treated types.
Double pitch roller chains are manufactured according to the respective 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 on 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 manufactured out of SAE-1045 case hardened steel with extra-hardened teeth and coated with black oxide. These sprockets are really durable, high-strength, and manufactured to high precision tolerances. Stock dual pitch sprockets include regular roller and carrier roller design, single duty sprockets are made to purchase and typically take from a couple of business days to a few weeks to manufacture based upon our factory loads and Double Pitch Chain Sprockets china sprocket specifics.
Standard Roller Type
Standard roller type sprockets are 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 engage with the chain on every other tooth because there are two teeth 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 seat and engage with each tooth. These sprockets will have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
Solitary duty sprockets are manufactured to where every tooth gets involved evenly on every revolution. This sprocket type has become obsolete generally in most applications but continues to be available.
When using double pitch roller chain it really is highly recommended if not necessary to use a double pitch sprocket. It is because double pitch sprockets are manufactured with a special 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 regular tooth profile and the picture on the right is the special double pitch sprocket profile. As possible plainly see above, the dual pitch sprockets tooth profile is certainly slightly 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 in addition to excessive wear. Something important to note is certainly that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is definitely 31 or more you can use a standard roller chain sprocket. This guideline 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 offers a long working life at a really great price! 2042A16 dual pitch sprockets are manufactured specifically for C2042 dual pitch roller chain, have 16 teeth, and completely meet all ANSI Specifications. Additionally, this sprocket includes 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 aside from others is that it’s Black Oxide Finished, temperature treated, and is manufactured 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 compared to the competition. Thanks to our sourcing experts, companions, and engineers, these sprockets are usually in stock and at a really great price. For prices and availability please e mail us and we will 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 use S rollers engage with almost every other tooth. Sprockets will have a longer life as chains engage with different teeth every time the rollers rotate (when actual number of teeth is odd).
Sprocket for Dual Pitch Chain
As shown 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 existence as less use and abrasion.
S roller type chain could work well with regular roller chain sprocket with an increase of than 30 teeth.
