Differences between deep groove ball bearings and angular contact ball bearings

Deep groove ball bearings and angular contact ball bearings are typical rolling bearings, which are widely used to withstand radial load and bidirectional axial load, suitable for high-speed rotation and occasions requiring low noise and low vibration. Sealed bearings with steel dust cover or rubber seal ring are pre-filled with grease, and bearings with stop ring or flange on outer ring are easy to locate axially. The size of the maximum load type bearing is the same as that of the standard bearing, but the inner ring and the outer ring are provided with a filling groove, so that the ball loading quantity is increased, and the rated load is improved.

In the aspect of structure, deep groove ball bearings and angular contact ball bearings with the same inner and outer diameters and widths have the same inner ring size and structure, but the outer ring size and structure are different:

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

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

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

The deep groove ball bearing is suitable for bearing radial force, small axial force, combined axial and radial load and moment load, while the angular contact ball bearing can bear single radial load, large axial load (varying with the contact angle), and the duplex ball bearing can bear bidirectional axial load and moment load.  The limit speed of angular contact ball bearings with the same size is higher than that of deep groove ball bearings.
