Double-toothed sprockets are offered either completely or in two tooth steps. Complete tooth guidelines are double-toothed so that only part of the teeth is used effectively. The advantage is that whenever the chain can be exchanged the so far unutilised 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 manufactured with fifty percent tooth steps. With every rotation the chain 
joints move one tooth ahead 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, 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.
