What is the structural difference between angular contact bearings and deep groove ball bearings?

Deep groove ball bearings and angular contact ball bearings are representative rolling bearings. They are widely used and can withstand radial loads and bidirectional axial loads. They are suitable for high-speed rotation and situations requiring low noise and low vibration. They are equipped with steel plate dust covers. Sealed bearings with rubber seals or rubber seals are pre-filled with grease. Bearings with snap rings or flanges on the outer ring are easy to axially position and install in the shell. The dimensions of the maximum load bearing are the same as standard bearings. , but there is another filling groove in the inner and outer rings, which increases the number of balls and increases the rated load.

1.Different types and load directions:

Deep groove ball bearings:

Deep groove ball bearings are the most common type of rolling bearings. It mainly bears radial load, but can also bear radial load and axial load at the same time. When it is only subjected to radial loads, the contact angle is zero. When deep groove ball bearings have large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small and the limit speed is also very high.

Angular contact ball bearings:

There is a contact angle between the ferrule and the ball. The standard contact angles are 15/25 and 40 degrees. The larger the contact angle, the greater the axial load capacity. The smaller the contact angle, the more conducive to high-speed rotation. Single-row bearings can withstand Radial load and one-way axial load. DB combination, DF combination and double row angular contact ball bearings can withstand radial load and two-way axial load. DT combination is suitable for larger one-way axial load and the rated load of a single bearing. Where insufficient, ACH type bearings are used for high speed, with small ball diameter and large number of balls, and are mostly used for machine tool spindles. In general, angular contact ball bearings are suitable for high-speed, high-precision rotation applications.

2.Differences in 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 shoulders on both sides of the outer ring channel, while angular contact ball bearings generally have single shoulders;

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

3.The outer ring channel position of deep groove ball bearings is different from that of angular contact ball bearings. The non-center position, its specific value is considered when designing angular contact ball bearings, and is related to the degree of contact angle;

3.In terms of uses:

The two have different uses. Deep groove ball bearings are suitable for bearing radial forces, small axial forces, shaft-radial combined loads and moment loads, while angular contact ball bearings can bear single radial loads and large axial loads. (Varies with different contact angles), double pairing (varying with different pairing methods) can withstand bidirectional axial load and moment load.

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