Various Clutch Bearing (CKS, CKA, CKB, CSK, CKD, HF, HFL, RC, RCB, FC, FCB)

One way clutch can overrun freely in one direction of rotation. Reverse rotation is instantaneously prevented by the automatic engagement of the clutch (another name is back stop, overrunning clutch). The full complement of cams made special alloy steel provides greater torque capacity than the other roller clutch. The dimpling of cam clutch is distributed around the inner raceway, not concentrated. Therefore, this offer long life performance, high precision without any backlash and silent operation than roller clutches. NFS-k, NSS-K, CKS, CKA, CKB, CSK, CKD series are applicated in general industrial, precision machinery (printer, textile machinery.
