[Features] Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they 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 with increasing contact angle. [Single row angular contact ball bearings] Single row angular contact ball bearings can accommodate axial loads acting in one direction only. A single row bearing is typically adjusted against a second bearing. The standard assortment of 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. [Double row angular contact ball bearings] 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  acting in both directions. They provide stiff bearing arrangements and are able to accommodate tilting moments. The standard assortment of double row angular contact ball bearings comprises bearings in the 32 A, 33 A and 33 D series. [Four point contact ball bearings] Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads acting 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.
