Details
Angular contact ball bearings are designed to handle radial and axial loads simultaneously. Due to their contact angle and construction, they offer higher axial load-carrying than standard deep groove ball bearings. It features a contact angle between the balls and the raceways, allowing it to distribute the loads more evenly and efficiently.
