1 Scope This Part of GB/T 307 specifies tolerances for boundary dimensions (except chamfer dimensions) and the running accuracy of radial rolling bearings specified in GB/T 273.1-2003, GB/T 273.3-1999 and GB/T 7217-2002. This 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). Tolerances for such bearings are given in the relevant Standards. Chamfer dimension limits are given in GB/T 274-2000. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this Part of GB/T 307.
