Double row angular contact ball bearings are specialized rotating components designed to accommodate both radial and axial loads by incorporating two rows of balls set at an angle to the bearing axis. This unique design enhances their ability to handle combined loads and provides improved rigidity. The arrangement of the inner and outer rings and the double-row configuration allow these bearings to achieve higher axial load-carrying capacity compared to single-row angular contact ball bearings. This makes them suitable for applications where both radial and axial forces are present, such as in machine tool spindles, pumps, and gearboxes. The contact angle between the balls and the raceways provides the bearings with excellent axial rigidity, contributing to their precise positioning capabilities. Double row angular contact ball bearings are valued for their versatility, reliability, and efficiency in various industrial contexts, where the need for handling multiple types of loads is paramount.
