Defines dimensional and geometrical characteristics, limit deviations from nominal sizes, and tolerance values to define the interface (except chamfers) of radial rolling bearings.

This International Standard specifies dimensional and geometrical characteristics, limit deviations from nominal sizes, and tolerance values to define the interface (except chamfers) of radial rolling bearings. Nominal boundary dimensions are defined in ISO15 , ISO355 [2] and ISO8443 [9] . This International Standard does not apply to certain radial bearings of particular types (e.g. needle roller bearings) or for particular fields of application (e.g. airframe bearings and instrument precision bearings). Tolerances for such bearings are given in the relevant International Standards. Chamfer dimension limits are given in ISO582 .
