Double-toothed sprockets are offered either completely or in two tooth steps. Full tooth techniques are double-toothed to ensure that only a part of the teeth is used effectively. The benefit is that when the chain is definitely exchanged the up to now unutilised teeth can be used then, and the sprockets can stay in the system.
In order to increase the life cycle of a chain drive even more, sprockets can be manufactured 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 frequently used when, due to the respective design, just minor deflections can be realised.
Our sprockets and plate sprockets are made of C 45, stainless steel, and special materials with a material strength of between 500 N/mm² and 600 N/mm². Aside from hardened toothing, we also supply surface area treated types.
