Main technical indicators:
1. Bearing accuracy index: over GB/307.1-94 P4 grade accuracy
2. High-speed performance index: dmN value: 1.3~1.8x 106 /min
3. Service life (average) : >1500 h
The service life of high-speed precision angular contact ball bearing has a great relationship with the installation:
1. The bearing shall be installed in a dust-free and clean room. The bearing shall be carefully selected and the bearing spacer shall be ground.
2. The bearing should be cleaned before installation. During the cleaning, the inner ring slope is facing upward with flexible hand induction and no sense of stagnation.
3. Special tools shall be used for bearing installation, and the force is uniform. Knocking is strictly forbidden.
4. Bearing storage should be clean and ventilated, without corrosive gas, relative humidity should not exceed 65%, long-term storage should be regularly rustproof.
1. Simple Design, be convenient when using
2. Low Friction coefficient
3. High limit speed
4. Short delivery time
5. Large stock
