Deep groove ball bearings and angular contact ball bearings are different

Deep groove ball bearings are a very common bearing. The bearings can carry loads in the longitudinal and axial directions, so the current industrial applications are still very widespread. Correspondingly, there are some similarities between the use range of this part and angular contact ball bearings, so what are the differences between the two? Let's give a blow introduction:

I. Deep groove ball bearings and angular contact ball bearings with the same inner and outer diameters 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 channel, while angular contact ball bearings are generally single shoulders;

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

3. The position of the outer ring channel of a deep groove ball bearing is different from that of an angular contact ball bearing, and its non-central position is a specific value that is taken into consideration when designing an angular contact ball bearing, which is related to the degree of contact angle.

In terms of use:

1. They are used for different purposes. Deep groove ball bearings are suitable for bearing radial forces, small axial forces, combined axial radial loads and moment loads, while angular contact ball bearings can withstand single radial loads and large axial loads (depending on the contact angle) Differing), double-pairing (different with different matching methods) can withstand bidirectional axial load and moment load.

2. Different speeds. The rotational speed of angular contact ball bearings of the same size is higher than that of deep groove ball bearings.

3. Different shoulders. Deep groove ball bearings have double shoulders on both sides of the outer ring channel, while angular contact ball bearings are generally single shoulders.

4. The outer ring channel curvature is different. The groove curvature of the outer ring of a deep groove ball bearing is different from that of an angular contact ball, and the latter is often larger than the former.
