Precision Angular Contact Ball Bearings

How to distinguish precision angular contact ball bearings from ordinary angular contact ball bearings?

1. The size values is not the same, and the dimensional deviation (inner diameter, outer diameter, ellipse, etc.) of products with high accuracy level is smaller than that of products with low accuracy level;

2. The required values of rotational accuracy are not the same, and the rotational accuracy of products with high accuracy level (inner radial runout, outer radial runout, end-facing raceway runout, etc.) is stricter than that of products with low accuracy level;

3. The required values of surface shape and surface mass are not the same, and the surface shape and surface mass (surface roughness of raceways or channels, circular deviation, groove deviation, etc.) of products with high accuracy level are stricter than the values required by products with low accuracy level;

4. The material properties of products with particularly high precision grade are more favorable than those of products with general accuracy grade.

The larger the contact angle of angular contact ball bearings, the greater the axial load they can withstand.

Conversely, the smaller the contact angle, the smaller the axial load that can be accommodated.

The smaller the contact angle, the more suitable it is for high-speed rotation and the greater the ability to withstand radial loads.
