标准范围

本文件规定了尺寸和几何特征、与标称尺寸的偏差限制以及公差值，以定义径向滚动轴承的界面（倒角除外）。标称边界尺寸在ISO 15、ISO 355[2]和ISO 8443[4]中定义。本文件不适用于特定类型的某些径向轴承（例如滚针轴承）或特定应用领域（例如机身轴承）。此类轴承的公差在相关国际标准中给出。ISO 582[3]中给出了倒角尺寸限制。

This document specifies dimensional and geometrical characteristics, deviation limits from nominal sizes, and tolerance values to define the interface (except chamfers) of radial rolling bearings. Nominal boundary dimensions are defined in ISO 15, ISO 355^[2] and ISO 8443^[4].

This document 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). Tolerances for such bearings are given in the relevant International Standards.

Chamfer dimension limits are given in ISO 582^[3].
