1) Except tapered bore. 2) Diameter series 7 and 8 not covered by ISO 492. 3) Applies to inner rings and outer rings of bearings of matched bearing sets consisting of two or more bearings. Does not apply to universally matchable angular contact ball bearings. 4) Applies to bearings prior to mounting and after removal of internal or external snap ring. 5) Capped bearings are sealed or shielded bearings.
