ABSTRACT: The prevailing cumulative failure curves of Rolling Contact Bearings
(RCB) have two main drawbacks: they begin at the origin and have a large
dispersion. The purpose of this study is to develop an ideal failure curve and
overcome the present drawbacks. The ideal failure curve of RC bearings is
obtained by applying a water-free lubricant to the tested bearings. This
eliminates the cavitation erosion from the Bimodal failure mechanism and the
synergistic effect with the mechanical failure mode. This new concept considers the fatigue process involved
in the failure mechanism and suggests decreasing the dispersion of bearing
life.
