A ball bearing is capable of withstanding radial and thrust loads. In addition, loads can be combined. Consider Fa and Fr as the axial thrust and radial loads, respectively, and Fe as the equivalent radial load that causes the same damage as the combined thrust and radial loads. What is the purpose of the rotation factor V in the equations?
