Sprockets for dual pitch roller chains are available in a single or double-toothed design. Single-toothed sprockets for dual pitch roller chains have the same behaviour as standard sprockets for roller chains according to ISO 606. Due to the bigger chain pitch of dual pitch roller chains it is possible to increase durability by toothing modifications.
Double-toothed sprockets are offered either completely or in two tooth steps. Full tooth actions are double-toothed to ensure that only a part of the tooth 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 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 decreases the wear 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 made from C 45, stainless steel, and special components with a material strength of between 500 N/mm² and 600 N/mm². Apart from hardened toothing, we also supply surface area treated types.
Double pitch roller chains are manufactured according to the respective 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 dual pitch roller chains are available in a single or in a double-toothed version.
Our in-stock standard double pitch sprockets are manufactured out of SAE-1045 case hardened metal with extra-hardened teeth and coated with black oxide. These sprockets are extremely durable, high-strength, and manufactured to high precision tolerances. Stock double pitch sprockets include regular roller and carrier roller design, solitary duty sprockets are made to order and typically take from a couple of business days to a few weeks to manufacture 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 permit proper seating of the chain. On even tooth-counts, these sprockets only engage with the chain on almost every other tooth because there are two the teeth per pitch. On odd tooth counts, any provided tooth is engaged only on almost every other revolution which of training course 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 engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
Single duty sprockets are produced to where every tooth gets engaged evenly on every revolution. This sprocket type has become obsolete in most applications but is still available.
When using dual pitch roller chain it is extremely recommended if not necessary to use a double pitch sprocket. It is because dual pitch sprockets are manufactured with a particular tooth profile that allows for the roller to correctly seat and build relationships the teeth of the sprocket. The above picture on the left is the standard tooth profile and the photo on the right is the special dual pitch sprocket profile. As you can see above, the double pitch sprockets tooth profile is definitely slightly deeper and cut differently to totally accept the dual pitch chain roller. If using a standard sprocket, failure to engage will result in chain jumping along with excessive wear. Something important to note is certainly that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is definitely 31 or even more you can use a standard roller chain sprocket. This guideline does not connect with carrier roller design chains which where the roller diameter exceeds the sidebar height, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
