Double-toothed sprockets are offered either in full or in half tooth steps. Complete tooth guidelines are double-toothed so that only a part of the the teeth is used effectively. The advantage is that when the chain is definitely exchanged the so far unutilised the teeth can be used then, and the sprockets can remain in the system.
In order to increase the life cycle of a chain drive even more, sprockets can be produced 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, due to the respective design, only minor deflections can be realised.
Our sprockets and plate sprockets are made from C 45, planetary gearbox stainless, and special components with a material strength of between 500 N/mm² and 
600 N/mm². Apart from hardened toothing, we also supply surface treated types.
