Sprockets for dual pitch roller chains are available in an individual or double-toothed design. Single-toothed sprockets for dual pitch roller chains possess the same behaviour as regular 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 can be found either in full or in half tooth steps. Full tooth actions are double-toothed so that only part of the teeth is used effectively. The advantage is that whenever the chain is certainly exchanged the up to now unutilised teeth can be used then, and the sprockets can remain in the system.
In order to increase the life cycle of a chain drive a lot more, sprockets can be manufactured 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 type of toothing is often used when, due to the respective design, just minor deflections can 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 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 upon pitch circle
Slot holes on hub and hole circle
Our sprockets for dual pitch roller chains are available 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 dark oxide. These sprockets are extremely durable, high-strength, and produced to high precision tolerances. Stock double pitch sprockets include regular roller and carrier roller style, single duty sprockets are made to order and typically take from a couple of business days to some weeks to produce based on our factory loads and sprocket specifics.
Standard Roller Type
Standard 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 also tooth-counts, these sprockets just build relationships the chain on almost every other tooth because there are two teeth per pitch. On odd tooth counts, any provided tooth is engaged only on every other revolution which of training course 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 chair and engage with 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 tooth gets involved evenly on each revolution. This sprocket type has become obsolete 
generally in most applications but is still available.
When using dual pitch roller chain it is extremely recommended if not required to use a dual pitch sprocket. The reason being dual pitch sprockets are manufactured with a particular tooth profile that allows for the roller to correctly seat and engage with the teeth of the sprocket. The above photo on the left is the regular 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 can be slightly deeper and cut differently to fully accept the dual pitch chain roller. If using a standard sprocket, failure to engage will lead to chain jumping and also 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 certainly 31 or even more you can make use of a typical roller chain sprocket. This guideline does not connect with carrier roller style 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.
