Double-toothed sprockets are offered either in full or in half tooth steps. Complete tooth techniques are double-toothed so that only a part of the tooth is used effectively. The benefit is that whenever the chain is usually exchanged the so far unutilised the teeth 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 produced with half tooth steps. With every rotation the chain joints move one tooth ahead in the meshing. This reduces the wear of the chain and the tooth edges. This sort of toothing is frequently used when, because of the planetary gearbox respective design, just minor deflections could be realised.
Our sprockets and plate sprockets 
are constructed with C 45, stainless steel, and special materials with a material strength of between 500 N/mm² and 600 N/mm². Apart from hardened toothing, we also supply surface area treated types.
