Sprockets for dual pitch roller chains can be found in a single or double-toothed style. 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 toughness by toothing modifications.
Double-toothed sprockets can be found either completely or in two tooth steps. Full tooth steps are double-toothed to ensure that only a part of the teeth is used effectively. The benefit is that when the chain is definitely exchanged the so far unutilised 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 even more, sprockets can be produced with fifty percent tooth steps. With every rotation the chain joints move one tooth ahead in the meshing. This decreases the wear of the chain and the tooth edges. This kind of toothing is often used when, due to 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. Apart from hardened toothing, we also supply 
surface area treated types.
Double pitch roller chains are produced according to the particular 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 on 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 double pitch sprockets are produced 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, solitary duty sprockets are created to purchase and typically take from a couple of business days to a few weeks to manufacture based on our factory loads and sprocket specifics.
Standard Roller Type
Standard roller type sprockets are the same outdoors diameter and width as the single-pitch equivalent just with a different tooth profile to permit proper seating of the chain. On even tooth-counts, these sprockets just build relationships the chain on almost every other tooth because there are two tooth per pitch. On odd tooth counts, any provided tooth is engaged just on 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 seat 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 engaged evenly on every revolution. This sprocket type has become obsolete generally in most applications but continues to be available.
When using double pitch roller chain it is highly recommended if not necessary to use a dual pitch sprocket. The reason being dual pitch sprockets are produced with a particular tooth profile that allows for the roller to correctly seat and engage with the teeth of the sprocket. The above photo on the left may be the regular tooth profile and the picture on the right may be the special double pitch sprocket profile. As you can see above, the double pitch sprockets tooth profile is somewhat deeper and cut differently to totally accept the double pitch chain roller. If utilizing a standard sprocket, failing to engage will result in chain jumping as well as 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 can be 31 or more you can make use of a standard roller chain sprocket. This rule does not connect with carrier roller style chains which where in fact the roller diameter exceeds the sidebar elevation, these chain sizes consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
