Installation method of angular contact ball bearings


Angular contact ball bearing, mainly used for high speed rotating occasions with light load, requires high precision, high speed, low temperature rise and low vibration and a certain service life of the bearing.It is often used as a supporting part of high speed motorized spindle in pairs.

Main technical indicators:

1. Bearing accuracy index: over GB/307.1-94 P4 accuracy

2. High speed performance index: dmN value of 1.3~1.8x 106 /min

3. Service life (average) : > 1500 h

The service life of high speed precision angular contact ball bearing is closely related to the installation

1. The bearing shall be installed in a clean and clean room. The bearing shall be carefully selected and matched.

2. The bearing should be cleaned before installation. When cleaning, the inner ring slope is up, the hand induction is flexible, and there is no sense of stagnation.

3. Special tools should be used for bearing installation, and the force should be even.

4. The bearing shall be stored with clean ventilation, no corrosive gas, and the relative humidity shall not exceed 65%. Long-term storage shall be regularly rust-proof.
