The work of preparing International Standards is normally carried
10、out 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
11、collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical 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 Internationa
12、l Standards. Draft International Standards adopted by the technical committees are circulated to the member 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 eleme
13、nts of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12090-1 was prepared by Technical Committee ISO/TC 4, Rolling bearings, Subcommittee SC 11, Linear motion rolling bearings. ISO 12090 consists of the followi
14、ng parts, under the general title Rolling bearings Profiled rail guides for linear motion rolling bearings: Part 1: Boundary dimensions and tolerances for series 1, 2 and 3 Part 2: Boundary dimensions and tolerances for series 4 and 5 BS ISO 12090-1:2011INTERNATIONAL STANDARD ISO 12090-1:2011(E) ISO
15、 2011 All rights reserved 1Rolling bearings Profiled rail guides for linear motion rolling bearings Part 1: Boundary dimensions and tolerances for series 1, 2 and 3 1 Scope This part of ISO 12090 establishes the boundary dimensions and tolerances for series 1, 2 and 3 of linear motion rolling bearin
16、gs, profiled rail guides. These bearings consist of profiled rails with carriages, which can support forces from all perpendicular directions and moments around all axes and consist of recirculating rolling elements. The internal design of these profiled rail guides is at the discretion of the manuf
17、acturer. An assembly, as specified by the manufacturer, can comprise one or more carriages on a profiled rail. Therefore, the interchange or combination of these elements can only be carried out within the limits permitted by the manufacturer. 2 Normative references The following referenced document
