Double-toothed sprockets can be found either completely or in half tooth steps. Full tooth steps are double-toothed to ensure that only a part of the teeth is used effectively. The benefit is that when the chain is planetary gearbox definitely exchanged the up to now unutilised tooth can be used after that, and the sprockets can stay in the system.
In order to increase the 
life cycle of a chain drive a lot 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 put on of the chain and the tooth edges. This sort of toothing is often used when, because of the respective design, just minor deflections could be realised.
Our sprockets and plate sprockets are made from 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 treated types.
