The AS series is composed of non-bearing-supported built-in one-way clutches developed by STIEBER. These bearings are needed to support axial and radial loads. When installing, these bearings must be lubricated and sealed. Compared to the 62 Series of ball bearings, they have the similar nominal outer dimensions. The inner race is keyed to the shaft except for the 6 mm bore. On the other hand, the outer race has a positive r6 tolerance to give be compatible in a H7 housing. This outer housing must have sufficient strength to avoid expansion after assembly.
