Lanyu bearing Experts briefly explain the models, dimensions and specifications of double-row angular contact ball bearings

L&Y is a professional manufacturer of precision bearings. The company has passed ISO9001:2000 international quality management system certification and adheres to the principle of "quality as the root and quality as the basis". Products are produced with enterprise standards that are higher than national standards. As always, we provide the best quality products to new and old customers and carefully build a well-known brand in the bearing industry.

When installing double-row angular contact ball bearings, it should be noted that although the bearings can withstand bidirectional axial loads, if there is a ball-filling gap on one side, it should be noted that the main axial load should not pass through the groove edge on the side with the gap. When using the bearings, it should be noted that the raceway on the side without the ball-filling gap bears the main load.

Single-row angular contact ball bearings can only withstand axial loads in one direction. When bearing radial loads, additional axial forces will be caused. And the axial displacement of the shaft or housing in one direction can only be limited. The contact angle of the angular contact ball bearing is 40 degrees, so it can withstand a large axial load. Angular contact ball bearings are non-separable designs, and the shoulders on both sides of the inner and outer rings are of different heights. In order to improve the load capacity of the bearing, the shoulder on one side will be processed lower so that more steel balls can be loaded into the bearing.

Double-row angular contact ball bearings can withstand large radial loads, combined radial and axial loads and torque loads, and limit the axial displacement of the shaft in both directions. It is mainly used in components that limit the bidirectional axial displacement of the shaft and the housing, and can withstand radial loads and axial loads at the same time. It can work at a higher speed. The larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.

The tiltability between the inner and outer rings of double-row angular contact ball bearings is limited. The allowable tilt angle depends on the internal clearance of the bearing, the bearing size, the internal design, and the force and torque acting on the bearing. The maximum allowable tilt angle should ensure that no excessive additional stress is generated in the bearing. If there is a tilt angle between the inner and outer rings of the bearing, it will affect the life of the bearing, and at the same time cause the bearing to have a reduced operating accuracy and increased operating noise. Double-row angular contact ball bearings generally use nylon cages or brass solid cages.
