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.

Single row angular contact ball bearings can only bear the axial load in one direction, when bearing the radial load, will cause additional axial force, must apply to the corresponding reverse load, therefore, this kind of bearings are generally used in pairs.Double-row angular contact ball bearings can bear larger radial and axial bidirectional combined load and torque load, mainly radial load. They can limit the two-way axial displacement of the shaft or shell, and the contact Angle is 30 degrees.

Features:

1. Simple Design, be convenient when using

2. Low Friction coefficient

3. High limit speed

4. Short delivery time

5. Large stock
