Differences in structure:

Deep groove ball bearings and angular contact ball bearings with the same inner and outer diameter and width dimensions have the same inner ring size and structure, but the outer ring size and structure are different

1. Deep groove ball bearings have double shoulders on both sides of the outer ring groove, while angular contact ball bearings generally have single shoulders;

2. The curvature of the outer ring of deep groove ball bearings is different from that of angular contact balls, the latter is often greater than the former;

3. The position of the outer ring of the deep groove ball bearing is different from that of the angular contact ball bearing. The specific value of the non-central position is considered during the design of the angular contact ball bearing and is related to the degree of contact angle;

Difference in using:

1. The two uses are different. Deep groove ball bearings are suitable for bearing radial force, smaller axial force, combined radial load and moment load, while angular contact ball bearings can bear single radial load and larger shaft Directional load (different with different contact angles), double pairing (different with different pairing methods) can bear bidirectional axial load and moment load.

2. The limiting speed is different. The limiting speed of angular contact ball bearings of the same size is higher than that of deep groove ball bearings.
