Stieber Clutch Built-In Freewheels Type ASNU

Type ASNU is a roller-type freewheel non-bearing supported. Bearings are required to support axial and radial loads. The installation must also provide lubrication and sealing. The 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 exact 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 an H7 housing. Additional side notches in the outer race provide for positive torque transmission.

If the housing is to K6 tolerance, the notches are unnecessary, but the housing must be strong enough not to expand after assembly. This design can accept an axial misalignment of the inner and outer race of ± S/2.
