Angular Conatact Ball Bearing

Angular contact ball bearings are specialized types of ball bearings designed to handle combined radial and axial loads simultaneously. They feature inner and outer ring raceways that are inclined relative to the bearing axis. This inclination enables them to support axial loads in both directions, allowing for higher axial load capacities compared to radial ball bearings. The contact angle between the balls and the raceways is typically around 15 to 40 degrees, which determines the bearing's ability to withstand axial loads. Angular contact ball bearings are commonly used in applications where high-speed rotation and precise axial positioning are required, such as machine tool spindles, pumps, gearboxes, and automotive applications.

These bearings are available in various configurations, including single-row, double-row, and four-point contact designs. Single-row angular contact ball bearings can accommodate axial loads in one direction only and are often paired in sets for applications requiring higher axial load capacity. Double-row angular contact ball bearings have two rows of balls separated by a central rib on the inner ring, providing increased radial and axial load-carrying capacity compared to single-row bearings. Four-point contact ball bearings have a unique design with four points of contact between the balls and the raceways, allowing them to withstand radial, axial, and moment loads simultaneously. Overall, angular contact ball bearings offer versatility and reliability in demanding mechanical systems.
