This article presents a non-linear model of deep groove ball bearing and results of simulation. Vibrations of this bearing are studied for a wide range of clearance. An evolution from periodic to chaotic vibrations is visible due to increase of clearance. A number of phenomena associated with non-linear dynamics are observed, for instance: bistability, chaotic vibrations, windows of periodical vibrations, jump of amplitude, period-doubling cascade leading to chaos, bifurcation directly leading to chaos, and self-similarity of a Poincaré section. Moreover, amplitudes of vibrations are presented as functions of clearance. This provides an opportunity to select failure modes. Unfortunately, relations clearance amplitude and amplitude - clearance are ambiguous.
