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 regular sprockets for roller chains in accordance to ISO 606. Because of the larger chain pitch of double 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 to ensure that only part of the the teeth is used effectively. The benefit is that whenever the chain is usually exchanged the so far unutilised tooth 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 fifty percent tooth steps. With every rotation the chain joints move one tooth forward in the meshing. This reduces the put on of the chain and the tooth edges. This kind of toothing is frequently used when, because of the respective design, just minor deflections can be realised.
Our sprockets and plate sprockets are made from 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 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 on pitch circle
Slot holes upon hub and hole circle

Our sprockets for double pitch roller chains can be found in a single or in a double-toothed version.

Our in-stock standard dual 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 produced to high precision tolerances. Stock dual pitch sprockets include standard roller and carrier roller style, one duty sprockets are created to purchase and typically take from a few business days to a few weeks to produce based on our factory loads and sprocket specifics.
Standard Roller Type
Regular roller type sprockets will be the same outdoors diameter and width as the single-pitch equivalent simply with a different tooth profile to allow appropriate seating of the chain. On actually tooth-counts, these sprockets only engage with the chain on every other tooth because there are two tooth per pitch. On odd tooth counts, any provided 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 chair and build relationships each tooth. These sprockets will have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
One 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 continues to be available.
When using dual pitch roller chain it is extremely recommended if not required to use a dual pitch sprocket. This is because dual pitch sprockets are manufactured with a particular 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 may be the standard tooth profile and the photo on the right is the special double pitch sprocket profile. As you can see above, the dual pitch sprockets tooth profile is slightly deeper and cut differently to fully accept the dual 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 is usually 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 design 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.
