7、 Teile, allgemeines Wlzlagerzubehr und Gehuse of the Normenausschuss Wlz- und Gleitlager (Rolling Bearings and Plain Bearings Standards Committee). Amendments This standard differs from DIN 628-4:1993-12 as follows: a) all axial internal clearance values have been “converted” so as not to take the m

8、easuring load into account; as a consequence the tolerances given in this edition of the standard are generally lower than those in the previous edition by the magnitude of elastic deformation of the ring and rolling element; b) in Table 2, a new class C4 has been added for the axial internal cleara

9、nce; c) values for bearings of dimension series 10 have been added; d) axial internal clearance values in all clearance classes have been harmonized as follows: 1) tolerances increase harmoniously with increasing size of bearing; 2) within each range of diameter, the range of tolerances between clea

10、rance classes is largely the same; e) the range of bore diameters has been extended from d = 240 mm to d = 260 mm; f) tolerances of retaining slots have been brought in line with ISO 20515; g) information on masses in Table 1 has been deleted; h) the normative references have been updated.
