Applications

Reducers , Flender Gearbox ,SEW Gearbox;
Overrunning clutch: for multiple-machine drives or to separate the inertia of masses of a driven machine from the driving
machine after it has been switched off.

Indexing clutch: which turns a shaft step by step, thus achieving indexed material feed or a variable speed.

Backstop clutch: to prevent a machine shaft turning backwards. In this case the overrunning clutch acts as a brake.
