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.

SKF spherical roller bearings tolerances. SKF spherical roller bearings Boundary dimensions: ISO 15: , except for the width of sealed bearings with a BS2- prefix. Tolerances: Normal, P5 running accuracy on request (designation suffix C08). Except for: SKF Explorer bearings (d ≤ 300 mm): P5 running accuracy; width tolerance at least 50%

Tolerance is also an important criteria for running accuracy. SKF deep groove ball bearings up to 110 mm outside diameter have a tolerance equal to ABEC.

sure bearing is square on the shaft and then apply pressure using a hammer or arbor press. To mount larger bearings that are not easily pressed onto a shaft, heat the bearing to a maximum temperature of (250°F). The bearing may be heated in clean oil or in a 10% - 15% emulsion of soluble oil for 30 minutes to 1 hour depending on bearing size.

SKF bearing tolerances. Tolerances for the width variation of the outer ring of Class 5, 4, and 2 are shown in Table 8.2.2.
