Sprockets for double pitch roller chains according to ISO 1275

Double-toothed sprockets are offered either in full or in half tooth steps. Full tooth steps are double-toothed so that only a part of the teeth is used effectively. The advantage is that when the chain is exchanged the so far unutilised teeth can be used then, and the sprockets can remain 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 ahead in the meshing. This reduces the wear 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 of 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 manufactured according to the respective order and customers’ specifications.

On request we supply sprockets with:

• Bore and grove
• Tapped and pin holes for bore
• Tapped and pin holes for bore on pitch circle
• Slot holes on hub and hole circle

Our sprockets for double pitch roller chains are available in a single or in a double-toothed version.
