Type AA is a roller type freewheel non-bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation.

Standard lubrication is oil. A typical installation is shown on the following page.

The inner race is keyed to the shaft. The fit for centering of the outer race must be to H7* tolerance. Connection of the outer race is via through bolts to grade 10.9 or better. This design can accept an axial misalignment of inner and outer race of ± S/2*.
