Single Row Angular Contact Ball Bearing
Single row angular contact ball bearings feature offset raceways that create a contact angle, enabling them to carry significant axial load in one direction in addition to radial load. They are ideal for high-speed spindles, pumps, and precision machinery where rigidity and accuracy are critical. Typically used in matched pairs to handle axial loads in both directions, these bearings deliver excellent running accuracy, high stiffness, and reliable performance under demanding operating conditions.
