Tolerance classes and the corresponding values for certain tolerance characteristics are specified in ISO 492 (for radial bearthese standards were aligned with general ISO GPS (Geometrical Product Specification) standards such as ISO 1101 and ISO 5459.
ISO 492:2014 specifies dimensional and geometrical characteristics, limit deviations from nominal values, and tolerance valuesace (except chamfers) of radial rolling bearings. The nominal boundary dimensions are defined in ISO 15, ISO 355 and ISO 8443.
