ASNU Series ASNU25 Needle Roller Clutch Bearing Gcr15 Freewheel Hub Assembly

ASNU Series ASNU25 Roller Type One Way Freewheel Bearings


Features of Roller Type One Way Freewheel Bearings

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 outer 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 tolerances, as shown on the following page. The inner race is keyed to the shaft.

The outer race has 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.

This design can accept an axial misalignment of inner and outer race of ± S/2.
