Materials used for manufacturing sintered bearings shall conform to ISO 5755.
5 Cylindrical bearings
Dimensions for cylindrical bearings are shown in Figure 1, Table 1 and Table 2.
The tolerances for the bearings after fitting and the tolerances for the housing and insertion pin are given below. In addition, the tolerances for the inside and outside iameters of the bearings before fitting are given.
Since the actual tolerances and combinations of tolerances in the as-delivered state depend upon the characteristics of the materials and the manufacturing methods, they should be discussed with the manufacturer.BS ISO 2795 pdf download.
