Even when making regular shaft bearing clearance based on radial clearance: When there is no special requirements, under the condition of no load, radial clearance of 15 to 35 um, users select reasonably outer ring and the hole of the interference fit is very important, too large amount of interference will make bearing radial clearance, and destruction of bearing, make water pumps can't normal work, practical work, in addition to the above reasons, you also need to consider due to temperature rise caused by thermal clearance amount is reduced, so the general recommendation forms such as amount of interference.
