First, the selection of mutual cooperation
The inner diameter specifications and diameter specifications of rolling angular contact ball bearings are manufactured according to the accuracy class, and the tightness level of the inner bore and shaft and the outer side and the housing bore of angular contact ball bearings is only completed according to the dimensional tolerance of the motor shaft and the dimensional tolerance of the housing bore. The base shaft system is selected for the interaction between the inner bore and the shaft of the angular contact ball bearing, and the base shaft system is selected for the interaction between the outer side of the angular contact ball bearing and the housing bore.
To properly select a suitable fit, it is important to understand the specific load standards, operating temperatures and other regulations of angular contact ball bearings, which can be difficult. Therefore, most of the conditions are selected according to the application of fine grinding.
Second, the load size
The amount of win between the throwing ring and the shaft or casing lies in the size of the load, and the heavier load is selected with a large amount of win, and the lighter load is selected with a smaller override.
