Sprockets for double pitch roller chains can be found in an individual or double-toothed design. 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 larger chain pitch of double pitch roller chains it is possible to increase durability by toothing modifications.
Double-toothed sprockets can be found either completely or in half tooth steps. Complete tooth guidelines are double-toothed so that only part of the teeth is used effectively. The benefit is that whenever the chain is usually exchanged the so far unutilised teeth can be used after that, and the sprockets can remain in the system.
In order to increase the life cycle of a chain drive a lot more, sprockets can be manufactured with fifty percent tooth steps. With every rotation the chain joints move one tooth forward in the meshing. This decreases the use of the chain and the tooth edges. This sort of toothing is often used when, because of the respective design, just minor deflections could be realised.
Our sprockets and plate sprockets are constructed with C 45, stainless, and special materials with a material power of between 500 N/mm² and 600 N/mm². Apart from hardened toothing, we also supply surface treated types.
Dual pitch roller chains are produced 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 on hub and hole circle
Our sprockets for double pitch roller chains are available in a single or in a double-toothed version.
Our in-stock standard dual pitch sprockets are manufactured out of SAE-1045 case hardened steel with extra-hardened teeth and coated with dark oxide. These sprockets are extremely durable, high-strength, and manufactured to high precision tolerances. Stock dual pitch sprockets include standard roller and carrier roller style, single duty sprockets are made 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 are the same outdoors 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 just engage with the chain on 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 program escalates the sprocket life.
Carrier Roller Type
Carrier roller type dual pitch sprockets are cut with space cutters to allow the carrier roller to properly chair and build relationships each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
One duty sprockets are manufactured to where every single tooth 
gets engaged evenly on each revolution. This sprocket type is becoming obsolete generally in most applications but continues to be available.
When using double pitch roller chain it is highly recommended if not required to use a double 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 the teeth of the sprocket. The above photo on the left is the regular tooth profile and the picture on the right may be the special dual pitch sprocket profile. As you can see above, the double pitch sprockets tooth profile can be 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 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 certainly 31 or even more you can use a standard roller chain sprocket. This rule does not apply to carrier roller style chains which where in fact the roller diameter exceeds the sidebar height, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
