Angular contact ball bearings

The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane along which the combined load is transmitted from one raceway to another and a line perpendicular to the bearing axis ()

The Anatomy of Angular Contact Bearings

The shoulder design of the outer raceway is the first noticeable difference you'll see in an angular contact bearing It creates two intersecting lines one that's formed at the point of contact between the ball and the two raceways and the other line that's formed from the perpendicular plane to the bearing
