Data required to ensure selection of correct fit. • Nature magnitude and direction of the load applied to the bearing. • Dimensions and internal clearance of the bearing. • Operating temperature. • Material, wall thickness and surface finish of bearing housing and shaft. • Ease of assembly and disassembly. • Type of machinery and degree of precision required. Standard recommendations for fits are shown in Tables 12 and 13 as a guide to correct selection. For ease of mounting and dismounting, large. selfaligning bearings are usually mounted by means of a tapered adapter sleeve or withdrawal sleeve, which provides an interference fit. Alternatively, cylindrical bore bearings can be used, but great care must be taken in the selection of a fit suited to the operating conditions, and also giving the optimum ease of mounting and dismounting. Under no circumstances must the interference exceed 1/1000th of the inner ring bore or outer ring diameter. The recommended shaft roundness tolerance is to be less than half the bearing bore tolerance, and the housing roundness tolerance is to be less than half the bearing outer ring tolerance. When using an adapter or withdrawal sleeve a somewhat wider diameter tolerance is acceptable on the shaft (h9), but the roundness tolerance should not be increased. Shaft and housing precision The degree of precision required for normal operating conditions are given in the following table. The use of bearings in excess of these limits may decrease bearing life, damage the cage etc. ITEM SHAFT HOUSING D imension precision I T6 (IT5) IT7 (IT5) Circularity (max) Cylindricity IT3 IT4 Shoulder runout tolerance IT3 IT3 Fit surface roughness Small bearings Medium to large bearings 0.8a 1.6a 1.6a 3.2a Note: In the case of precision bearings, precision must be kept to approximately 1/2 for circularity and cylindricity. 189
