It supersedes BS5983-1:1989, BS5983-2:1982, BS5983-3:1982 and BS5983-4:1982, which are withdrawn. The UK participati

13、13BSISO12240-1:1998 BSI 06-1999 iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standard bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body in
14、terested 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 collaborates closely with the International Electrotechni
15、cal Commission (IEC) on all matters of electrotechnical standardization. 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 least75% of the member bodies casting a vote. In
16、ternational Standard ISO12240-1 was prepared by Technical Committee ISO/TC 4, Rolling bearings, Subcommittee SC7, Spherical plain bearings. This first edition cancels and replaces ISO6124-1:1987, ISO6124-2:1982, ISO6124-3:1982 and ISO6125:1982 of which it constitutes a technical revision. ISO12240 c
17、onsists of the following parts, under the general title Spherical plain bearings: Part 1: Radial spherical plain bearings; Part 2: Angular contact radial spherical plain bearings; Part 3: Thrust spherical plain bearings; Part 4: Spherical plain bearing rod ends. Descriptors: Bearings, plain bearings
18、, spherical bearings, radial bearings, form specifications, dimensions, dimensional tolerances, clearances.iv blankBSISO12240-1:1998 BSI 06-1999 1 1 Scope This part of ISO12240 specifies dimension series, tolerances and radial internal clearances for radial spherical plain bearings. The dimensions a
19、nd tolerances specified in this part of ISO12240 have been selected to permit the design of radial spherical plain bearings using a wide choice of sliding material combinations. The specified tolerance values apply to finished, radial spherical plain bearings before any coating, plating, ring splitt
20、ing or ring fracturing. In the case of surface treated radial spherical plain bearings, there may be slight deviations from the specified tolerance values. Radial spherical plain bearings need not conform to the designs illustrated but compliance is required as regards the dimensions, tolerances and
21、 radial internal clearances specified. NOTESpherical plain bearings for airframe applications are not covered by this part of ISO12240. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO12240. At the time
22、 of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO12240 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
