The ASNU series by Stieber is a non-bearing supported built-in one way clutch which serves as a support to an axial and radial loads. Upon installation, it should be provided with a sealing and lubrication for efficient use. It comes with a nominal outer diameter which is just the same as for 63 ball bearing series. This is ideal to install bearing that has same location tolerance. On the other hand, its outer race has a positive n6 tolerance which enables it to give a press fit in a H7 housing. For additional side notches, it gives the outer race to have a positive torque transmission. Plus, it has a housing that has K6 tolerance.
