Sprockets for dual pitch roller chains are available in a single 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 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 half tooth steps. Complete tooth measures are double-toothed to ensure that only part of the teeth is used effectively. The advantage is that when the chain is certainly exchanged the so far unutilised teeth can be used after that, and the sprockets can stay in the system.
In order to boost the life cycle of a chain drive even more, sprockets can be produced 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 type of toothing is frequently used when, due to the respective design, just minor deflections could be realised.
Our sprockets and plate sprockets are constructed with 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.
Dual 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 upon pitch circle
Slot holes on 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 double pitch sprockets are produced out of SAE-1045 case hardened metal 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 regular roller and carrier roller style, one duty sprockets are created to order and typically take from a few business days to some 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 permit proper seating of the chain. On even tooth-counts, these sprockets just build relationships the chain on almost every other tooth because there are two tooth per pitch. On odd tooth counts, any provided tooth is engaged only on 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 permit the carrier roller to properly seat and build relationships each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
Solitary duty sprockets are produced to where every tooth gets engaged evenly on every revolution. This sprocket type is becoming obsolete in most applications but continues to be available.
When using dual pitch roller chain it really is highly recommended if not required to use a dual pitch sprocket. It is because dual pitch sprockets are produced with a particular tooth profile which allows for the roller to correctly seat and build relationships one’s teeth of the sprocket. The above picture on the left may be the standard tooth profile and the photo on the right may be the special dual pitch sprocket profile. As possible plainly see above, the double pitch sprockets tooth profile is definitely slightly deeper and cut differently to fully accept the double pitch chain roller. If utilizing a standard sprocket, failing to engage will result in chain jumping and also excessive wear. Something important to note can be that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count can be 31 or even more you can make use of a typical roller chain sprocket. This rule does not connect with 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.
