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 standard sprockets for roller chains in accordance to ISO 606. Because of the bigger chain pitch of dual pitch roller chains you’ll be able to increase toughness by toothing modifications.
Double-toothed sprockets can be found either in full or in two tooth steps. Full tooth actions are double-toothed so that only part of the tooth is used effectively. The benefit is that whenever the chain can be exchanged the up to now unutilised the teeth can be used then, and the sprockets can remain in the system.
In order to boost the life cycle of a chain drive a lot more, sprockets can be produced with half tooth steps. With every rotation the chain joints move one tooth ahead in the meshing. This reduces the put on of the chain and the tooth edges. This sort of toothing is frequently used when, because of the respective design, only minor deflections can be realised.
Our sprockets and plate sprockets are made of C 45, stainless, and special components with a material power 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 on 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 black oxide. These sprockets are extremely durable, high-strength, and produced to high precision tolerances. Stock dual pitch sprockets include regular roller and carrier roller design, one duty sprockets are created to purchase and typically take anywhere from a couple of business days to a few weeks to manufacture 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 simply with a different tooth profile to permit correct seating of the chain. On also 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 only on every other revolution which of course escalates the sprocket life.
Carrier Roller Type
Carrier roller type dual 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 equivalent.
Single Duty Type
Solitary duty sprockets are produced to where every single 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 highly recommended if not required to use a dual pitch sprocket. It is because double pitch sprockets are produced with a special tooth profile that allows for the roller to correctly seat and build relationships the teeth of the sprocket. The above picture on the left may be the standard tooth profile and the picture on the right may be the special dual pitch sprocket profile. As possible plainly see above, the double pitch sprockets tooth profile is somewhat deeper and cut differently to fully accept the double pitch chain roller. If utilizing 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 can be 31 or even more you can use a typical roller chain sprocket. This guideline does not 
apply to carrier roller design chains which where the roller diameter exceeds the sidebar height, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
