NF ISO 492, E22-335 (09/2023)

This document specifies dimensional and geometric characteristics, deviation limits from nominal sizes and tolerance values for defining the interface (except rounding) of radial roller bearings. Nominal overall dimensions are defined in ISO 15, ISO 355[2] and ISO 8443[4]. This document does not apply to certain particular types of radial bearings (e.g. needle roller bearings) or to certain particular areas of application (e.g. airframe bearings). Tolerances for such bearings are given in the relevant International Standards. Limits for rounding dimensions are given in ISO 582[3].
