Stieber Built In Freewheels AE
A roller-type freewheel without integrated bearings
Type AE is a roller-type freewheel without integrated bearings. Bearings are required to support both axial and radial loads, and lubrication and sealing must be provided by the installation. The nominal outside diameter corresponds to a standard ball bearing dimension.
A typical arrangement is to install this freewheel beside a bearing with the same housing diameter tolerance. The inner race is keyed to the shaft, and the outer race has an h6 tolerance and should be fitted in a housing with a K7 tolerance. Additional side notches provide for positive torque transmission.
If the housing tolerance is R6, 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 misalignment of the inner and outer races of ± S/2.
