SKF angular contact ball bearings have raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. This means that angular contact ball bearings are designed to accommodate combined loads, simultaneously acting radial and axial loads.
The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. 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 load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.

SKF single row angular contact ball bearing
SKF single row angular contact ball bearings can accommodate axial loads in one direction only. A single row bearing is typically adjusted against a second bearing. These SKF bearings are non-separable and the bearing rings have one high and one low shoulder. The low shoulder enables a large number of balls to be incorporated in the bearing, giving it a relatively high load carrying capacity. The standard assortment of SKF single row angular contact ball bearings comprises bearings in the 72 B(E) and 73 B(E) series. Some sizes in the 70 B series are also available.
SKF double row angular contact ball bearings
SKF double row angular contact ball bearings correspond in design to two single row angular contact ball bearings arranged back-to-back, but take up less axial space. They can accommodate radial loads as well as axial loads in both directions. They provide stiff bearing arrangements and are able to accommodate tilting moments. The standard assortment of SKF double row angular contact ball bearings comprises bearings in the 32 A, 33 A and 33 D series.
SKF four-point contact ball bearings
SKF four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can be supported. These bearings take up considerably less axial space than double row bearings.
