4、.See Explanatory notes for relationship to International Standard ISO 5753 : 1991, published by the Interna-tional Organization for Standardization.AmendmentsThis standard differs from the August 1987 edition as follows:a) The radial internal clearance values have been harmonized with those specifie
5、d in ISO 5753.b) The number of bore diameter ranges has been extended.c) The standard has been editorially revised.Previous editionsDIN 620: 1932-11, 1936-03; DIN 620-1: 1942-08, 1963-03, 1978-01, 1982-06; DIN 620-4: 1962-03, 1968-10,1983-09, 1987-08.All dimensions are in millimetres.1 ScopeThis sta
6、ndard specifies radial internal clearance values for radial contact groove ball bearings, self-aligningball bearings, cylindrical roller bearings, needle roller bearings and self-aligning roller bearings. These valuesare given for all five types of bearing with cylindrical bore, and also for self-al
7、igning bearings (ball or rollerbearings) and cylindrical roller bearings with tapered bore.The values given apply to bearings which are not mounted and are under no load condition (i.e with nomeasuring load applied).Since measurements of radial clearance can only be made with a measuring load applie
8、d, the radial displace-ment resulting from the elastic deformation of the rings and rolling elements shall be added to the valuesspecified in this standard, the magnitude of these values depending on the number and diameter of the rollingelements and on the extent of contact between rolling elements
9、 and raceway. As these design features arenot standardized, the magnitude of any additional displacement under the effect of a measuring load cannotbe allowed for in this standard. It is recommended that these data be requested from the bearing manufac-turer. The relevant measuring methods are descr

However, the responsible technical committee has notadopted the C5 clearance values, since bearings with a
47、radial internal clearance greater than the C4 range aregenerally not required in general applications.The normal clearance (CN) is the clearance usually adopted in the majority of cases. Bearings manufacturedto have such a clearance, as specified in this standard, will run satisfactorily under norma
48、l operating conditions.Other relevant standardsDIN 616 Rolling bearings General plan for boundary dimensionsDIN 620-1 Gauging methods for dimensional and running tolerances for rolling bearingsDIN 620-2 Tolerances for radial ball bearingsDIN 620-3 Tolerances for thrust bearingsDIN 620-6 Chamfer dimension limits for rolling bearings
