Internal Radial Clearance of ball and roller bearings is an important parameter in obtaining proper machine operation, optimal bearing life, and a reasonable operating temperature. With radial bearings of the deep groove ball, cylindrical roller, and spherical roller types, the term Internal Radial Clearance - IRC - is commonly employed.

The tolerances for the dimensions and running accuracy of bearings are set out in ISO 492/199/582. This largely corresponds to DIN 620. Accuracy of rolling bearings › Tolerances for bore and outside diameters, ring and bearing width › Tolerances for inscribed and circumscribed circle diameters of rollers › Tolerances for chamfer dimensions

2) Refer to Appendix Table 11 on page C22 for the values of standard tolerance grades IT. (3) Refer to Tables 9.13.1 and 9.13.2 for the recommended fits of shafts used in electric motors for deep groove ball bearings with bore diameters ranging from 10 mm to 160 mm, and for cylindrical roller bearings with bore diameters

286 and JIS B 0401 (dimension tolerances and fits). Accordingly, bearing fits are determined by the precision (dimensional tolerance) of the shaft diameter and housing bore diameter. Widely used fits for various shaft and housing bore diameter tolerances, and bearing bore and outside diameters are shown in Fig. 7.1.
