The CKF-A is a non-contact ratchet-type one-way clutch with the inner ring rotating. Only the inner ring is designed for one-way operation, without bearing support. A bearing must be installed during use to ensure concentricity between the inner and outer rings.
When used for anti-reversal purposes, the speed must not be less than the low allowable value of the override speed, as specified in the table on the next page.
This model is primarily used to prevent reverse under high-speed operating conditions and can also be applied to a two-speed drive switching device for high-speed overrunning and low-speed wedging of super-speed clutches.
