There are three types of ball bearings: angular contact (which we'll discuss shortly), axial, and deep-groove. Regardless of the type of ball bearing, their purpose is to reduce rotational friction and all are able to support both axial and radial (or thrust) force.

Are angular contact bearings better?

Angular contact bearings have a much higher speed rating than radial bearings because of the nonstop contact of the balls to both rings. ... Angular contact bearings can carry both radial and axial loads.

What is the difference between angular contact bearing and ball bearing?

The difference between these and deep groove ball bearings is that the bearing cross-section is designed asymmetrically. Angular contact ball bearings are designed to support loads whose line of application is not perpendicular to the bearing axis but rather at a certain angle to the perpendicular axis (contact angle).
