GB/T 307.4-2017 (English Version) PDF

Scope: This part of GB/T 307 specifies the dimensional characteristics of thrust bearings, the limit deviations from the nominal dimensions and tolerance values to limit the interface of thrust bearings (except for chamfers). Nominal dimensions are given in ISO1045. It can be divided into thrust bearings (such as special thrust precision bearings) that can be used for the failure of the basic character (such as the outer shaft) and the special combination. Tolerances for these bearings are given in the corresponding standards for chamfer size limits given in ISO 582 [9]. The nominal inner diameter of the shaft ring of double direction bearings da Ad2mp SCS | In any cross-section, the average size of the inner diameter of the shaft ring (from two-point dimensions) and its nominal size Vd2sp In any cross-section of ACS, the range of the two-point dimensions of the inner diameter of the shaft ring 1 354 Nominal outer diameters of seats 1 2, 3, 4 ADmp In any section of ACS, the deviation of the average size of the outer diameter of the seat ring (from two points) from its nominal size 1, 233 VDsp In any section of ACS, the deviation of the outer diameter of the seat ring Range 2,3,4 for two point sizes
