(1) Among the bearing parameters, the contact angle has a greater influence on the change in axial clearance.
(2) Among the influences of interference fit, centrifugal effect, and temperature rise on bearing clearance, interference fit has the greatest impact.
(3) In practical applications, if the bearing has an interference fit, the influence of the fit interference on the bearing clearance needs to be taken into account, and a certain amount of clearance should be reserved to avoid excessive pre-tightening force and premature failure of the bearing. When the angular contact ball bearings are actually paired, the change in radial clearance should be converted into the change in axial clearance for consideration
