In angular contact bearings the motion of the ball on the race involves both rolling and spinning. Recent work provides theories of the generation of a lubricant film, by hydrodynamic mechanisms, for each of these motions considered in isolation. By comparison of these theories, and using knowledge of the kinematics of bearings, it has been possible to provide an estimate of the relative importance of the rolling and spinning motions for film generation in angular contact bearings.
