- Tolerances for tapered bores.
- Diameter series 7 and 8 not covered by ISO 492:2014.
- 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.
- Applies to bearings prior to mounting and after removal of internal or external snap ring.
- Capped bearings are sealed or shielded bearings.
