27、for additional sale or distribution.Rolling bearings Thrust bearings Geometrical product specification (GPS) and tolerance values1 ScopeThis International Standard specifies dimensional characteristics, limit deviations from nominal values, and tolerance values to define the interface (except chamfe
28、rs) of thrust rolling bearings. Nominal boundary dimensions are defined in ISO 1041.This International Standard is not applicable to certain thrust bearings (e.g. thrust needle roller bearings) or for particular fields of application (e.g. special thrust precision bearings). Tolerances for such bear
29、ings are given in the relevant International Standards.Chamfer dimension limits are given in ISO 5823.2 Normative referencesThe following documents in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited
30、 applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 5593, Rolling bearings VocabularyISO 14405-1, Geometrical product specifications (GPS) Dimensional tolerancing Part 1: Linear sizesISO/TS 17863, Geometrical product specification (G
31、PS) Geometrical tolerancing of moveable assemblies3 Terms and definitionsFor the purposes of this document, the terms and definitions in ISO 5593, ISO 14405-1, and ISO/TS 17863 apply.4 SymbolsTo express that the ISO/GPS system, ISO 8015 7is applied, the dimensional characteristics shall be included
32、in the technical product documentation (for example on the drawing). The dimensional specifications, associated to these characteristics, are described in Table 1 and Figures 1 to 4.Descriptions for symbols are in accordance with GPS terminology; relationships with traditional terms are described in
33、 Annex A.A tolerance value associated to a characteristic is symbolized by t followed by the symbol for characteristic, for example, tdmp.In this International Standard, the ISO default specification operator for size is in accordance with ISO 14405-1, i.e. the two-point size is valid. Some specific
34、ation modifiers are described in Annex D.The detailed definitions for terms in ISO 14405-1 and traditional terms in ISO 1132-14are not fully equal, for differences, see Annex C.INTERNATIONAL STANDARD ISO 199:2014(E) ISO 2014 All rights reserved 1Copyright by ISO.
