The work of preparing International Standards is normally carried out through IsO non-governmental,inliaisonwithIsO,also take partin the work.Iso collaborates closely withthe International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEc 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 bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. rights. IsO shall not be held responsible for identifying any or all such patent rights. ISO 10285 was prepared by Technical Committee ISO/TC 4, Rolling bearings, Subcommittee SC 11, Linear motion rolling bearings. This second edition cancels and replaces the first edition (IsO 10285:1992), which has been technically revised. iv @ ISO 2007 - All rights reserved ISO 10285:2007(E) Introduction Linear motion rolling bearings provide for linear motion as opposed to rotational motion. The sleeve type linear ball bearing described in this International Standard uses balls which circulate in a number of closed loops in the cylindrical bearing that surrounds the shaft. a) b) low force required to produce relative linear motion between the bearing and the shaft. bearing type and specification is to be established between the manufacturer and the user. @ISO2007-All rights reserved INTERNATIONAL STANDARD ISO 10285:2007(E) Rolling bearings Sleeve type linear ball bearings Boundary dimensions and tolerances Scope This International Standard specifies the boundary dimensions, tolerances and definitions for sleeve type linear motion ball bearings. It is applicable to the size ranges covered by Table 1. 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 reference document (including any amendments) applies.
