Sprockets for dual pitch roller chains are available in an individual or double-toothed style. Single-toothed sprockets for dual pitch roller chains possess the same behaviour as standard sprockets for roller chains according to ISO 606. Because of the larger chain pitch of double pitch roller chains you’ll be able to increase durability by toothing modifications.
Double-toothed sprockets can be found either in full or in two tooth steps. Complete tooth measures are double-toothed to ensure that only a part of the the teeth is used effectively. The benefit is that when the chain is certainly exchanged the so far unutilised teeth can be used then, and the sprockets can remain in the system.
In order to raise 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 put on of the chain and the tooth edges. This sort of toothing is often used when, because of the respective design, only minor deflections can be realised.
Our sprockets and plate sprockets are made from C 45, stainless steel, 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.
Dual 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 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 dual pitch sprockets are manufactured out of SAE-1045 case hardened metal with extra-hardened teeth and coated with dark oxide. These sprockets are really durable, high-strength, and produced to high precision tolerances. Stock double pitch sprockets include standard roller and carrier roller design, single duty sprockets are made to order and typically take from a couple of business days to a few weeks to produce based on our factory loads and sprocket specifics.
Standard Roller Type
Regular roller type sprockets are the same outside diameter and width as the single-pitch equivalent just with a different tooth profile to allow appropriate seating of the chain. On actually 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 only on almost every other revolution which of course escalates 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 engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
Solitary duty sprockets are manufactured to where every tooth gets engaged evenly on each revolution. 
This sprocket type has become obsolete generally in most applications but continues to be available.
When using dual pitch roller chain it is extremely recommended if not necessary to use a double pitch sprocket. This is because double pitch sprockets are produced with a special tooth profile that allows for the roller to correctly seat and engage with the teeth of the sprocket. The above photo on the left is the standard tooth profile and the photo on the right is the special dual pitch sprocket profile. As you can plainly see above, the double pitch sprockets tooth profile is certainly somewhat deeper and cut differently to fully accept the dual 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 certainly that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is definitely 31 or more you can use a standard roller chain sprocket. This rule does not apply to carrier roller design chains which where the roller diameter exceeds the sidebar elevation, these chain sizes consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
