Angular contact ball bearings are precision-engineered components designed to accommodate combined radial and axial loads. They feature inner and outer ring raceways with angular contact points, enabling them to support both axial and radial forces simultaneously. This design allows for high-speed rotation and excellent performance in applications where high precision and reliability are crucial, such as machine tool spindles, automotive transmissions, and robotics. Angular contact ball bearings come in various configurations, including single row, double row, and four-point contact, catering to different load and speed requirements across industries.
