Double-toothed planetary gearbox sprockets are offered either in full or in two tooth steps. Complete tooth steps are double-toothed to ensure that only a part of the the teeth is used effectively. The advantage is that whenever the chain is definitely exchanged the so far unutilised teeth can be used after that, and the sprockets can remain in the system.

In order to increase the life cycle of a chain drive a lot more, sprockets can be manufactured with half tooth steps. With every rotation the chain joints move one tooth ahead in the meshing. This reduces the use of the chain and the tooth edges. This sort of toothing is often used when, due to the respective design, just minor deflections can be realised.

Our sprockets and plate sprockets are made from C 45, stainless steel, 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.

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