14、olling Bearings Standards Committee). It is basedon the International Standards listed in Annex A.AmendmentsThis standard differs from the June 1994 edition as follows:a) Specifications for the extension of the general plan have been included.b) For radial bearings, dimension series 27, 51, 52, 61 a

15、nd 62 have been included.c) Tables 10 to 20 listing the dimension series for needle roller bearings, radial needle roller and cageassemblies, and open end and closed end drawn cups have been included.d) The dimension plans for radial ball bearings and radial roller bearings of diameter series 7 and

16、for single-direction deep groove thrust ball bearings with flat housing washer, cylindrical roller thrust bearings and self-aligning thrust bearings of diameter series 2, 3 and 4 have been extended.e) Dimension plans for the chamfer dimensions of angular contact radial ball bearings have been includ

17、ed(cf. tables 29 and 30).f) Dimension series 10 has been included in the dimension plan for thrust collars for standard type cylindricalroller bearings. Series 24 has been dropped.g) The standard has been editorially revised.Previous editionsDIN Kr 1965: 1938-09; DIN 71965: 1940-07; DIN 616-1: 1940-

Inaddition, it describes the system of di

19、mension plans and series making up the general plan.This standard does not provide information regarding the internal design of rolling bearings (e.g. bearing rings,rolling elements, cages, seals), nor does it specify which dimension series and plans are suitable for particularbearing types. These a

20、re given in the relevant product standards.The objective of this standard is to restrict the number of bearing sizes enough to ensure economic productionand yet to provide a sufficient number of sizes to satisfy present and future needs of bearing users.2 Normative referencesThis standard incorporat

27、er dimensions for outerring non-thrust side3 System of dimension series and plans3.1 GeneralThe general plan specifies the major boundary dimensions of rolling bearings, i.e. bore diameter, outsidediameter, width or height, and the chamfer dimension, r, which is equal to the minimum chamfer dimensio

28、n, rsmin(cf. ISO 104).For ease of reference, table 1 lists the bore diameters, d, ranging from 0,6 mm to 2000 mm, and the associatedcode numbers. As a rule, the nominal bore diameter can be determined by multiplying the code number with afactor of 5. For bore diameters of less than 20 mm and of 500

29、mm or more, the code numbers are identical tothe bore diameters. For bore diameters of 10 mm, 12 mm, 15 mm and 17 mm, code numbers are specified fromwhich the bore diameter cannot be derived as explained above.Table 1: Bore diameters, d, and associated code numbersdCodedCodedCodedCodedCodedCodenumbe

33、erived using certain calculation factors. For the differentwidths and heights to be assigned to one particular sectional width or height of each diameter series, width serieshave been set up for radial bearings and height series for thrust bearings, where B and T values are given whichhave also been

34、 derived using certain factors.The values for the minimum chamfer dimension, r, have been derived from the sectional width or height of thebearing or from the specified B and T values.The values for the other boundary dimensions have been obtained by calculation or specified on a case-by-casebasis.T

35、he combination of a diameter series with a width series forms a dimension series for radial bearings and thecombination of a diameter series with a height series forms a dimension series for thrust bearings. A dimensionplan is made up of the boundary dimensions assigned to a dimension series.Diamete

36、r, width and height series are identified by codes.For diameter series, the following codes are used: 7, 8, 9, 0, 1, 2, 3, 4 and 5 for radial and thrust bearings; 7C, 8C, 9C, 0C, 1C, 2C, 3C, 4C, and 5C for radial needle roller and cage assemblies; 7D, 8D, 9D, 0D, 1D, 2D, 3D, 4D, and 5D for open end

37、and closed end drawn cup needle roller bearings; 7E, 8E, 9E, 0E, 1E, 2E, 3E, 4E, and 5E for thrust collars (reinforced type only).Page 4DIN 616 : 2000-06The arrangement of series is such that the outside diameter, and thus the sectional height or width of the bearingrelated to one particular bore di

38、ameter, increases from left to right.For width and height series, the following codes are used: 8, 9, 0, 1, 2, 3, 4, 5, 6 and 7 for radial bearings; 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 for radial needle roller and cage assemblies and for open end and closed enddrawn cup needle roller bearings; 7, 8, 9,

39、 0, 1, 2, 3, 4, 5, and 6 for thrust bearings.The arrangement of series is such that the width or height related to one particular sectional width or height orto one particular bore diameter increases from left to right.Figure 1: System of dimension seriesThe dimension series and plans depend on the

40、bearing type for which they are specified. Plans which cover thesame dimension series but relate to different bearing types do not necessarily include the same boundarydimensions.Where in product standards dimensions are to be specified, this shall be done by choosing the relevantdimension series fr

41、om the general plan relevant to the particular bearing type. Dimension series may be adoptedfully or in part and may be supplemented where necessary.3.2 Rules for the extension of the plan3.2.1 GeneralFor any new dimension not specified in this standard, the following rules shall serve as a guide.
