Axial (thrust) bearings support loads parallel to the axis of the shaft, such as those exerted by a table supporting a weight. Radial bearings support rotating wheels and other applications where the force of the load is perpendicular to the shaft. Ball bearings are used with applications that have high axial loads and low-to-moderate radial loads.
