Sprockets for dual 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 according to ISO 606. Because of the bigger chain pitch of dual pitch roller chains you'll be able to increase strength by toothing modifications.
Double-toothed sprockets can be found either completely or in half tooth steps. Full tooth techniques are double-toothed so that only a part of the the teeth is used effectively. The advantage is that whenever the chain is usually exchanged the up to now unutilised the teeth can be used after that, and the sprockets can stay 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 forward in the meshing. This reduces the wear of the chain and the tooth edges. This kind of toothing is often used when, because of 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 strength 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 on pitch circle
Slot holes upon hub and hole circle
Our sprockets for dual 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 really durable, high-strength, and manufactured 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 from a few business days to a few weeks to produce based upon our factory loads and sprocket specifics.
Standard Roller Type
Standard roller 
type sprockets will be the same outside diameter and width as the single-pitch equivalent simply with a different tooth profile to allow appropriate seating of the chain. On also tooth-counts, these sprockets just build relationships 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 almost every other revolution which of course 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 build relationships 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 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 is extremely recommended if not necessary to use a dual pitch sprocket. The reason being dual pitch sprockets are produced with a particular tooth profile which allows for the roller to properly seat and build relationships one's teeth of the sprocket. The above picture on the left may be the regular tooth profile and the picture on the right is the special dual pitch sprocket profile. As you can 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 result in chain jumping in addition to excessive wear. Something vital that you note can be that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is definitely 31 or even more you can use a typical roller chain sprocket. This guideline does not connect with carrier roller design 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.
