Sprockets for double pitch roller chains can be found in an individual or double-toothed design. Single-toothed sprockets for double 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 strength by toothing modifications.

Double-toothed sprockets can be found either in full or in two tooth steps. Complete tooth methods are double-toothed to ensure that only part of the tooth is used effectively. The benefit is that when 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 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 decreases the put on of the chain and the tooth edges. This type of toothing is frequently used when, because of the respective design, only minor deflections could be realised.
Our sprockets and plate sprockets are made of C 45, stainless steel, and special materials with a material strength of between 500 N/mm² and 600 N/mm². Aside from hardened toothing, we also supply surface area treated types.
Double pitch roller chains are manufactured 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 on pitch circle
Slot holes upon hub and hole circle

Our sprockets for double pitch roller chains can be found 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 dark oxide. These sprockets are really durable, high-strength, and produced to high precision tolerances. Stock double pitch sprockets include regular roller and carrier roller style, single duty sprockets are created to purchase and typically take anywhere from a couple of business days to some weeks to manufacture based on our factory loads and sprocket specifics.
Standard Roller Type
Regular roller type sprockets will be the same outdoors diameter and width as the single-pitch equivalent just with a different tooth profile to allow correct seating of the chain. On even tooth-counts, these sprockets only build relationships the chain on every other tooth because there are two the teeth per pitch. On odd tooth counts, any given tooth is engaged just 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 chair and engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
Single duty sprockets are manufactured to where every tooth gets involved evenly on every revolution. This sprocket type has become obsolete 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 double pitch sprockets are produced with a special tooth profile which allows for the roller to correctly seat and build relationships one’s teeth of the sprocket. The above picture on the left may be the standard tooth profile and the picture on the right is 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 totally accept the double pitch chain roller. If utilizing a standard sprocket, failure to engage will result in chain jumping in addition to excessive wear. Something vital that you note is 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 use a standard roller chain sprocket. This guideline does not connect with carrier roller design chains which where the roller diameter exceeds the sidebar elevation, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
