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 standard sprockets for roller chains according to ISO 606. Due to the bigger chain pitch of double pitch roller chains it is possible to increase sturdiness by toothing modifications.

Double-toothed sprockets can be found either in full or in two tooth steps. Full tooth measures are double-toothed so that only a part of the teeth is used effectively. The advantage is that whenever the chain is certainly 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 manufactured with half tooth steps. With every rotation the chain joints move one tooth ahead in the meshing. This decreases the use of the chain and the tooth edges. This sort of toothing is frequently used when, due to the respective design, just minor deflections can be realised.
Our sprockets and plate sprockets are made of C 45, stainless, and special components 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 particular 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 upon pitch circle
Slot holes on hub and hole circle

Our sprockets for dual pitch roller chains are available in a single 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 extremely durable, high-strength, and produced to high precision tolerances. Stock dual pitch sprockets include regular roller and carrier roller style, solitary duty sprockets are created to purchase and typically take from a few business days to some weeks to produce based upon our factory loads and sprocket specifics.
Standard Roller Type
Regular roller type sprockets will be the same outside diameter and width as the single-pitch equivalent simply with a different tooth profile to allow proper seating of the chain. On even tooth-counts, these sprockets only build relationships the chain on almost 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 course increases the sprocket life.
Carrier Roller Type
Carrier roller type double pitch sprockets are cut with space cutters to permit the carrier roller to properly seat and build relationships each tooth. These sprockets could have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
One duty sprockets are manufactured to where every tooth gets involved evenly on each revolution. This sprocket type has become obsolete generally in most applications but continues to be available.
When using double pitch roller chain it really is extremely recommended if not required to use a dual pitch sprocket. It is because double pitch sprockets are produced with a special tooth profile which allows for the roller to correctly seat and engage with one’s teeth of the sprocket. The above photo on the left is the standard tooth profile and the photo on the right may be the special double pitch sprocket profile. As possible plainly see above, the dual pitch sprockets tooth profile is definitely somewhat deeper and cut differently to totally accept the double pitch chain roller. If utilizing a standard sprocket, failure to engage will lead to chain jumping as well as excessive wear. Something vital that you note is definitely that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is definitely 31 or more you can make use of a typical roller chain sprocket. This guideline does not connect with carrier roller style chains which where the roller diameter exceeds the sidebar height, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
