Complete freewheel clutch units

GMN complete freewheel clutch units are particularly suited for high torque requirements. The FPD, FND, RA, FP and FN series are characterized by an integrated ball bearing and an additional roller bearing (fixed and floating bearing) and are also optionally available pre-lubricated with sealing rings. All GMN complete freewheel clutch units can be used as indexing clutches, backstops or as overrunning clutches.
