Rolling bearings - Radial bearings - Tolerances

ISO 492 specifies tolerances for boundary dimensions (except chamfer dimensions) and the running accuracy of radial rolling bearings specified in ISO 15, ISO 355 and ISO 8443.This International Standard does not apply to certain radial bearings of particular types (e.g., drawn cup needle roller bearings) or for particular fields of application (e.g., airframe bearings and instrument precision bearings).
