    ASNU Series

    Model ASNU is a ramp & roller type clutch, non-bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing are required.


    Nominal outer diameter is the same as a Series 63 ball bearing.

    • The outer race has positive n6 toler- ance, to give a press fit in a H7 housing . Additional side notches in the outer race provide positive torque transmission.
    • If the housing is to K6 tolerance, use of the notches is not necessary, but the housing must be strong enough not to expand after assembly.
    • This design can accept an axial misalign- ment of inner and outer race of +/- S/2.
    • These clutches are oil dipped at the factory but must be filled to the proper level before operation.
    • This clutch is designed for oil lubrication . For grease lubrication, reduce the maximum overrunning speed to 50% of listed value.
