The service life of high-speed precision angular contact ball bearings is closely related to the installation. The following items should be noted:
1. The bearing installation should be carried out in a dust-free and clean room. The bearing should be carefully selected and the spacer ring for the bearing should be ground. On the premise of keeping the same height of the inner and outer ring spacers, the parallelism of the spacers should be controlled below 1um
 2.The bearing should be cleaned before installation, the inner ring slopes upwards when cleaning, the hand feels flexible, and there is no sense of stagnation. After drying, Put in the specified amount of grease, if it is oil mist lubrication, put in a small amount of oil mist oil.
 3. Special tools should be used for bearing installation, and the force should be uniform, and no beating.
 4. The bearing should be stored in clean and ventilated, free of corrosive gas, and the relative humidity should not exceed 65%, long-term storage should be regularly rust-proof.
