6、he International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical commit

7、tee 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 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotech

8、nical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member

9、 bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying

10、 any or all such patent rights. ISO 12043 was prepared by Technical Committee ISO/TC 4, Rolling bearings.

11、amfer dimensions for loose rib and non-rib sides 1 Scope This International Standard specifies the minimum chamfer dimensions for loose rib and non-rib sides of single-row cylindrical roller bearings of diameter series 0, 2, 3, and 4 (except dimension series 24) as specified in ISO 15. Indication is

12、 given for those minimum chamfer dimensions that are identical to those in ISO 15. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the
