The ASNU series roller type one way freewheel clutch bearing catalogue:

The roller type ASNU series clutch bearing description:

Type ASNU is a roller 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.

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 mis-alignment of inner and outer race of +-S/2.
