Sprockets for dual pitch roller chains can be found in an individual or double-toothed style. Single-toothed sprockets for double pitch roller chains possess the same behaviour as standard sprockets for roller chains according to ISO 606. Because of the bigger chain pitch of double pitch roller chains you’ll be able to increase strength by toothing modifications.

Double-toothed sprockets are offered either completely or in two tooth steps. Complete tooth methods are double-toothed so that only part of the teeth is used effectively. The advantage is that whenever the chain is usually exchanged the up to now unutilised teeth can be used after that, 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 forward in the meshing. This reduces 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 could be realised.
Our sprockets and plate sprockets are constructed with C 45, stainless steel, and special materials 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 request 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 double 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 dark oxide. These sprockets are really durable, high-strength, and manufactured to high precision tolerances. Stock dual pitch sprockets include standard roller and carrier roller style, one duty sprockets are made to order and typically take anywhere from a couple of business days to a few weeks to produce 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 allow proper seating of the chain. On actually tooth-counts, these sprockets just engage with the chain on almost every other tooth because there are two teeth per pitch. On odd tooth counts, any given tooth is engaged only 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 build relationships each tooth. These sprockets could have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
Solitary duty sprockets are manufactured to where every single tooth gets engaged evenly on every revolution. This sprocket type is becoming obsolete generally in most applications but is still available.
When using double pitch roller chain it really is extremely recommended if not necessary to use a double pitch sprocket. This is because double pitch sprockets are manufactured with a special tooth profile which allows for the roller to properly 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 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 double pitch chain roller. If using a standard sprocket, failure to engage will result in chain jumping and also excessive wear. Something vital that you note is usually that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is usually 31 or even more you can make use of a standard roller chain sprocket. This guideline does not connect with carrier roller style chains which where in fact the roller diameter exceeds the sidebar height, these chain sizes consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
