Double-toothed sprockets are offered either completely or in two tooth steps. Full tooth methods are double-toothed so that 
only part of the tooth is used effectively. The benefit is that when 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 even more, sprockets can be manufactured 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 type of toothing is frequently used when, due to the respective design, just minor deflections can be planetary gearbox realised.
Our sprockets and plate sprockets are made of C 45, stainless, and special components with a material power of between 500 N/mm² and 600 N/mm². Apart from hardened toothing, we also supply surface treated types.
