Sprockets for double pitch roller chains are available in an individual or double-toothed design. Single-toothed sprockets for double pitch roller chains have the same behaviour as regular sprockets for roller chains in accordance to ISO 606. Due to the bigger 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 two tooth 
steps. Complete tooth techniques are double-toothed so that only part of the teeth is used effectively. The benefit is that when the chain can be exchanged the up to now unutilised teeth can be used then, and the sprockets can remain in the system.
In order to raise the life cycle of a chain drive a lot 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 type of toothing is often used when, because of the respective design, only minor deflections could be realised.
Our sprockets and plate sprockets are made from 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.
Dual pitch roller chains are produced according to the particular 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 upon hub and hole circle
Our sprockets for dual 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 produced to high precision tolerances. Stock double pitch sprockets include regular roller and carrier roller design, single duty sprockets are created to order and typically take anywhere from a couple of 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 outdoors diameter and width as the single-pitch equivalent just with a different tooth profile to permit correct seating of the chain. On even tooth-counts, these sprockets only engage with the chain on almost every other tooth because there are two the teeth per pitch. On odd tooth counts, any provided tooth is engaged just on almost every other revolution which of program increases 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 engage with 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 tooth gets involved evenly on each revolution. This sprocket type is becoming obsolete generally in most applications but continues to be available.
When using dual pitch roller chain it really is extremely recommended if not necessary to use a double pitch sprocket. The reason being dual pitch sprockets are manufactured with a special tooth profile which allows for the roller to properly seat and engage with one’s teeth of the sprocket. The above photo on the left may be the standard tooth profile and the photo on the right may be the special dual pitch sprocket profile. As you can see above, the dual pitch sprockets tooth profile is certainly somewhat deeper and cut differently to fully accept the dual pitch chain roller. If using a standard sprocket, failure to engage will result in chain jumping and also excessive wear. Something vital that you note is certainly that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is usually 31 or more you can use a typical roller chain sprocket. This guideline does not apply to carrier roller style chains which where in fact the roller diameter exceeds the sidebar height, these chain sizes consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
