Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. 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. Single row angular contact ball bearings SKF single row angular contact ball bearings can accommodate axial loads in one direction only. This type of bearing is typically adjusted against a second bearing. Their bearing rings have an upper and a lower shoulder and are non-separable. Bearing Features: High load carrying capacity - The lower shoulder enables a large number of balls to be incorporated in the bearing, giving it a relatively high load carrying capacity. Good running properties - Rapid accelerations and decelerations are possible. Easy mounting of universally match able bearings - No adjustment is needed for correct internal clearance or preload.
