Q: What are the advantages and disadvantages of the angular contact ball bearing?
Angular contact ball bearings can bear both radial and axial loads. It can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. The contact angle is the angle between the contact line of the ball and raceway in the radial plane and the vertical line of the bearing axis. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of the axial force, the contact angle will increase. Angular contact ball bearings are divided into double-row angular contact ball bearings and single-row angular contact ball bearings.
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 forces and moments acting on the bearing. There will be no excessively high additional stress in the bearing. If there is an inclination 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's running accuracy to decrease and the running noise to increase
Double-row angular contact ball bearings should be installed with attention. Although the bearings can withstand two-way axial loads, if there is a ball gap on one side, care should be taken not to let the main axial load pass through the groove side of the gap. When using the bearing, care should be taken to make the side raceway without the ball loading notch bear the main load.
