Angular contact ball bearings are precision-engineered bearings designed to support combined radial and axial loads while operating at high speeds. Here's a description of angular contact ball bearings:

1. Angular Contact: Angular contact ball bearings have raceways in the inner and outer rings that are designed to accommodate angular misalignment between the shaft and housing. This angular contact allows the bearing to support both radial and axial loads simultaneously.

2. Single and Double Row Configurations: Angular contact ball bearings are available in single-row and double-row configurations. Single-row bearings have one row of balls and are suitable for applications with relatively light loads, while double-row bearings have two rows of balls and can handle higher loads.

3. Contact Angle: Angular contact ball bearings have a contact angle, which is the angle formed by the line of contact between the balls and the raceways in the radial plane. Common contact angles include 15°, 25°, and 40°, each offering different load-carrying capacities and stiffness.

4. High-Speed Capability: Angular contact ball bearings are designed for high-speed applications where precise rotation and low friction are critical. The design minimizes internal friction and enables smooth operation at high rotational speeds.

5. Variety of Cage Designs: Angular contact ball bearings may feature different cage designs, including pressed steel, machined brass, or synthetic materials. The cage serves to retain and separate the balls, ensuring proper spacing and alignment.

6. Preload: Angular contact ball bearings can be preloaded to enhance rigidity and reduce clearance in the bearing assembly. Preloading involves applying a controlled axial force to the bearing during installation to eliminate any internal clearance, improving accuracy and responsiveness.

7. Lubrication: Proper lubrication is essential for optimal performance and longevity of angular contact ball bearings. They are often supplied with grease or oil lubrication, and some may have lubrication holes and grooves to facilitate the distribution of lubricant.

8. Mounting Arrangements: Angular contact ball bearings can be mounted in various arrangements, including back-to-back, face-to-face, or tandem configurations, to accommodate different load directions and moments.
