FAG spindle bearings accuracy, tolerance

The main dimensions of the FAG spindle bearings conform to DIN 628-1. The dimensional tolerances of the bearings correspond to tolerance class P4, the running tolerances correspond to tolerance class P2 to DIN 620-2.

The actual value codes for the bore and outside diameter as well as the nominal value deviation for the bearing width are indicated on the end faces of the inner and outer rings as well as on the packaging, where they are stated in the sequence “bore/outside diameter/bearing width”.
