Double-toothed planetary gearbox sprockets are offered either completely or in two tooth steps. Complete tooth actions are double-toothed so that only part of the the teeth is used effectively. The benefit is that when the chain is exchanged the so far 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 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 kind of toothing is often used when, because of the respective design, only 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.

Double pitch roller chains are produced according to the respective order and customers’ specifications.
