Computer simulations of the dynamics performance of roller bearings, as obtained by the computer code ADORE, are used to model the infuence of race out-of-roundness, race taper and centrality of land on partly crowned rollers. Both oil and solid lubricated high-speed roller bearings are considered and the overall performance parameters, such as, bearing life, heat generation, cage interactions and race flange wear due to roller skew and tilt, are correlated to the magnitude of the various geometrical imperfections. Thus the strength of computer modeling approach to optimization of geometrical tolerances in cylindrical roller bearings is demonstrated.
