tolerance between shaft and bearing

3/3/2020· Higher operating accuracy requires smaller tolerance between shaft and bearing, such as higher tolerances than level 5. If the temperature of the inner ring of the FAG bearing is higher than that of the bearing during operation, the fit will loosen and exceed the allowable value. This requires a tighter fit, such as replacing m6 with k6.
