Angular contact ball bearing has high limit rotational speed, they can carry radial load and axial load simultaneously, they can also withstand purely radial load. The axial load carrying capacity depends on the magnitude of contact angle and increases with increasing contact angle. Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools, for which high running accuracy is required.Single row angular contact ball bearings can carry axial load acting in one direction only.

Aligning roller bearings have two rows of rollers, mainly bearing radial loads, but also can withstand axial loads in either direction. It has high radial load capacity, especially suitable for heavy loads or dynamic loads, but cannot withstand pure axial loads. This kind of bearing outer ring raceway is spherical shape, so its aligning performance is good, can compensate for the coaxial error.Self-aligning roller bearings are divided into two different structures according to the roller cross section shape: symmetrical spherical roller bearings and asymmetric spherical roller bearings.
