Angular contact ball bearings are bearings that can withstand radial and axial loads. It has a higher rotational speed than a normal bearing. The contact angle of the angular contact ball bearing is the angle between the line connecting the contact points of the ball and the vertical line of the raceway and the bearing shaft in the radial plane. The larger the contact angle, the higher the axial load carrying capacity. High precision and high speed bearings typically require a contact angle of 15 degrees. Under axial force, the contact angle will increase.
Structure and classification
Angular contact ball bearing have raceways in the inner and outer rings, and the inner and outer rings can be displaced relative to each other along the axial direction of the bearing. These bearings are particularly suitable for withstanding composite loads, ie loads that act simultaneously in both radial and axial directions. The contact angle of the angular contact ball bearing is the angle between the line connecting the contact point of the ball and the raceway in the radial plane and the vertical line of the bearing axis. The axial load-bearing capacity of the angular contact ball bearing increases as the contact angle α increases.
Angular contact ball bearing are generally classified into single row angular contact ball bearings and double row angular contact ball bearings. Bearing typically use a 15-degree contact angle.
