Angular contact ball bearings
Overview

Angular contact ball bearings from Western Bearing House

Angular contact ball bearings have raceways offset along the axis, so loads pass through the balls at a contact angle. This lets them carry heavy axial loads in one direction together with radial loads. They are used singly, in matched pairs, or as double row bearings for loads in both directions.
