Sprockets for double pitch roller chains are available in a single 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 larger chain pitch of dual pitch roller chains it is possible to increase strength by toothing modifications.
Double-toothed sprockets are offered either in full or in half tooth steps. Full tooth actions are double-toothed to ensure that only part of the teeth is used effectively. The advantage is that when the chain is definitely exchanged the up to now unutilised the teeth can be used then, and the sprockets can remain in the system.
In order to increase 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 forward in the meshing. This reduces the wear of the chain and the tooth edges. This kind of toothing is often used when, due to the respective design, just minor deflections could be realised.
Our sprockets and plate sprockets are made of 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 treated types.
Double 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 upon 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 double pitch sprockets are produced out of SAE-1045 case hardened steel with extra-hardened teeth and coated with black oxide. These sprockets are extremely durable, high-strength, and manufactured 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 manufacture based upon our factory loads and sprocket specifics.
Standard Roller Type
Standard roller type sprockets are the same outdoors diameter and width as the Double Pitch Chain Sprockets single-pitch equivalent just with a different tooth profile to allow correct seating of the chain. On actually tooth-counts, these sprockets just build relationships the chain on almost every other tooth because there are two the teeth per pitch. On odd tooth counts, any given tooth is engaged only on almost 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 comparative.
Single Duty Type
One duty sprockets are manufactured 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 double pitch roller chain it really is highly 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 picture on the left is the standard 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 definitely slightly deeper and cut differently to fully accept the dual pitch chain roller. If using a standard sprocket, failing to engage will result in chain jumping and also excessive wear. Something important to note is usually that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is 31 or more you can make use of a standard roller chain sprocket. This rule does not apply to carrier roller design chains which where in fact 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
This 2042A16 sprocket is durable, exceeds in quality, and will be 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 Standards. Additionally, this sprocket has a stock bore but we are able to supply the sprocket already bored out to almost any requested bore size. A thing that sets this 2042A16 sprocket apart from others is that it is Black Oxide Finished, high 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 compared to the competition. Thanks to our sourcing experts, partners, and engineers, these sprockets are usually in share and at an extremely great price. For prices and availability please contact us and we will be happy to assist you.

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