1. When installing the angular contact ball bearing, the force should be uniform, and it should not be hammered directly. For example, if the interference is large, the bearing should be heated in an air heating furnace or oil furnace with automatic temperature control, and the heating temperature should be strictly controlled below 100°.

2. Angular contact ball bearings equipped with nylon cages can work continuously and stably for a long time at -40°-120°, and should not work for more than 4 hours at 150°, and the short-term temperature peak can reach 180°.

3. The warehouse where the angular contact ball bearings are stored should be clean, dry and not allowed to be stored in the same warehouse with chemical products; the relative humidity should not exceed 65%, and the bearings are not allowed to be stored on the ground.
