Double-toothed sprockets can be found either in full or in two tooth steps. Complete tooth planetary gearbox actions are double-toothed so that only a part of the teeth is used effectively. The advantage is that when the chain is definitely exchanged the so far unutilised teeth can be used after that, and the sprockets can stay in the system.
In order to boost the life cycle of a chain drive a lot more, sprockets can be produced with half tooth steps. With every rotation the chain joints move one tooth forward in the meshing. This reduces the use of the chain and the tooth edges. This kind 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 steel, and special components with a material power of between 500 N/mm² and 600 N/mm². Aside from hardened toothing, we also supply surface area treated types.

On request we supply sprockets with:
