For example, the usual temperature, under the industrial and mining, small and medium-sized deep groove ball bearings working clearance recommended: 4-11um. (Note that not all bearings, not large deep groove balls.)

Secondly, you said that the change in bearing clearance, directly speaking the change in tolerance, in fact, there is one aspect to pay attention to, that is, temperature changes, thermal expansion and contraction caused by the change in play. This must be taken into consideration when calculating.

The method of selecting the clearance is to subtract the small gap between the original clearance and the tolerance caused by the tolerance, and then subtract the change of the clearance caused by the temperature change, and the obtained working clearance is in accordance with the basic operating conditions.
