The work of preparing International Standards is normally carried out

11、through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO coll

12、aborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approv

13、al criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the sub

18、hine element geometry standard as defined in the geometrical product specification (GPS) system as presented in the matrix model of ISO 146387.The fundamental rules of ISO/GPS given in ISO 80153 apply to this International Standard and the default decision rules given in ISO 14253-15apply to the spe

19、cifications made in accordance with this International Standard, unless otherwise indicated.The connection between functional requirements, measuring technique and measuring uncertainty is always intended to be considered. The traditionally used measuring technique is described in ISO 1132-22. For m

20、easurement uncertainty it is intended that ISO 14253-26should be considered.For small radial bearings, when D 30 mm, manufacturing a snap ring groove might distort the raceways. As such, it is recommended to use bearings with a flanged outer ring instead. Information about snap ring grooves and snap

21、 rings for these small bearings can be found in Annexes A and B.Annexes C and D contain informative information on snap ring material and an example of correct application.Annex E contains an example of a real drawing indication of a snap ring groove.
