Axial internal clearance or preload of FAG bearing series 70..-B, 72..-B and 73..-B of universal design, in pairs in an X or O arrangement.
The axial internal clearance or freedom from clearance do not apply to fitted bearing pairs. If rigid fits are used, this leads to reduced axial internal clearance or increased preload of the FAG bearing pair.
