Sprockets for dual pitch roller chains can be found in a single or double-toothed design. 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 bigger chain pitch of dual pitch roller chains you’ll be able to increase sturdiness by toothing modifications.

Double-toothed sprockets are offered either completely or in two tooth steps. Complete tooth actions are double-toothed to ensure that only part of the teeth 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 remain in the system.
In order to increase 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 decreases the use of the chain and the tooth edges. This kind of toothing is often used when, due to the respective design, only minor deflections can be realised.
Our sprockets and plate sprockets are constructed with C 45, stainless, and special materials with a material power of between 500 N/mm² and 600 N/mm². Apart from hardened toothing, we also supply surface treated types.
Dual 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 upon pitch circle
Slot holes on hub and hole circle

Our sprockets for dual pitch roller chains can be found in a single or in a double-toothed version.

Our in-stock standard double pitch sprockets are manufactured out of SAE-1045 case hardened steel with extra-hardened teeth and coated with dark oxide. These sprockets are extremely durable, high-strength, and manufactured to high precision tolerances. Stock double pitch sprockets include regular roller and carrier roller design, one duty sprockets are made to order and typically take 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 are the same outdoors diameter and width as the single-pitch equivalent simply with a different tooth profile to allow correct seating of the chain. On even tooth-counts, these sprockets only engage with the chain on 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 training course 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 comparative.
Single Duty Type
Solitary duty sprockets are manufactured to where every single tooth gets engaged evenly on each revolution. This sprocket type is becoming obsolete in most applications but is still available.
When using dual pitch roller chain it really is highly recommended if not necessary to use a dual pitch sprocket. This is because dual pitch sprockets are produced with a special tooth profile which allows for the roller to properly seat and build relationships one’s teeth of the sprocket. The above photo on the left may be the standard tooth profile and the photo on the right is the special double pitch sprocket profile. As you can see above, the double pitch sprockets tooth profile can be somewhat deeper and cut differently to fully accept the dual pitch chain roller. If utilizing a standard sprocket, failure to engage will lead to chain jumping and also 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 make use of a standard roller chain sprocket. This guideline does not connect with carrier roller design chains which where in fact the roller diameter exceeds the sidebar height, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
