• Angular Contact Ball Bearings


Angular Contact Ball Bearings

Angular contact ball bearings are widely used bearings, which are Ultraior in their ability to withstand axial loads and are more suitable for high-speed operation. The axial load carrying capacity of angular contact ball bearings is related to the contact angle. The larger the contact angle, the greater the axial load that can be carried. The contact angle is controlled by the radial clearance of the bearing.


Angular contact ball bearing function

  1. Under load, a contact angle will naturally form, which can bear radial load and unidirectional axial load at the same time. The load bearing capacity changes with the size of the contact angle. The larger the contact angle, the greater the axial load capacity. The contact angle is divided into 15°, 30° and 40°.
  2. Increase the number of steel balls to obtain better bearing strength. At the same time, a rib of the inner ring or outer ring is processed into a slope form. The separate type does not need to be locked, and the non-separated type must be designed with a certain amount of lock. Make sure not to fall apart. This kind of bearing is often used in high-speed operation places. In order to balance the axial force, paired installation is often used, so there are three forms of face-to-face, back-to-back and the same direction. With the advancement of science and technology and the different working conditions of the bearing, angular contact ball bearings have a variety of structural forms.
  3. Angular contact ball bearings mainly bear larger unidirectional axial loads. The greater the contact angle, the greater the load-bearing capacity. The material of the cage is steel plate, brass or engineering plastic, and the forming method is stamping or turning, depending on the bearing form or use conditions.
  4. It can support the work of the motor. The essence of support is to be able to bear the load in the corresponding direction. It can also be understood as it is used to fix the shaft. Another understanding is to fix the shaft so that it can only achieve rotation, while controlling its axial and radial movement. The motor cannot work at all without bearings. Because the shaft may move in any direction, and the motor is required to only rotate when it is working.

Angular contact ball bearing features

  • 1. Unique structure

    The shape of angular contact ball bearings is similar to that of deep groove ball bearings. One ring has only one rib and the other side is sloped. Unlike deep groove ball bearings, there are more steel balls in the cage and assembly.

  • 2. Sophisticated components

    The cages used in angular contact ball bearings include iron cages, copper cages, aluminum alloy cages and plastic cages in terms of materials. The cages are solid or stamped and do not require rivets.

  • 3. The speed is very high

    The higher speed of angular contact ball bearings refers to the limit value that does not produce frictional heating that causes burns and can rotate continuously, which is higher than other types of bearings of the same size.

  • 4. Two-way load

    In addition to being able to bear radial loads, it can also bear larger unidirectional axial loads. Its axial load capacity is determined by the contact angle and increases with the increase of the contact angle.

  • 5. Use in pairs

    Generally, angular contact ball bearings are used in pairs, because the outer rings of a pair of bearings can be opposed, that is, the wide end faces the wide end face, and the narrow end faces the narrow end face. In this way, additional axial force can be avoided, and the shaft or housing can be restricted to the axial clearance range in both directions.

  • 6. Excellent accuracy

    During operation, the angular contact ball bearing can eliminate the internal clearance of the angular contact ball bearing due to the axial load after installation, which also relatively improves the rotation accuracy of the angular contact ball bearing.

  • 7. High bearing capacity

    When angular contact ball bearings are used in pairs, they can withstand bidirectional axial loads and increase the carrying capacity of unilateral axial loads.

  • 8. Good rigidity

    Because of the clearance of angular contact ball bearings, the inner and outer rings must move relative to each other under load, which will reduce the rigidity of the bearing. In order to reduce vibration, the angular contact ball bearings are often installed with preloading methods to eliminate the original Clearance, greater rigidity can be obtained and the original accuracy characteristics can be maintained for a long time.
