one way clutch bearing

ASNU series clutch bearing is a sprag one way clutch.The noise is low and the torque is large.

 clutch bearing ASNU series is a sprag type freewheel non bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation.

Nominal outside diameter is the same as a series 63 ball bearing.

A typical arrangement is to install this type alongside a bearing within the same location tolerance as shown on the following page.

The inner race is keyed to the shaft. The outer race has a positive n6 tolerance. to give a press fit in a H7 housing. Additional side notches in the outer race provide for positive torque transmission.

If the housing is to K6 tolerance, use of the notches is not necessary, but the housing must be strong enough to not expand after assembly.

The design can accept an axial misalignment of inner and outer race of ±S2.
