Comparison Study between Theoritical and Numerical Analyses for Ball Bearing

In this paper, a comparison study has been presented to see the difference between the theoretical and finite element analysis for ball bearing. Throughout that study, a finite element analysis is performed to determine the maximum contact pressure and maximum stresses induced in the bearing components; rolling elements and rings. Another purpose of this analysis is to validate the most critical zones in the bearing for knowing the scenario of generating this stress and pressure which enabling the specialists to determine the initiation point for failure in the bearing. The comparison between the results of the numerical study with theoretical one has showed the good agreement outputs of this numerical study. In addition, this analysis could give the displacements and deformations that raised in the bearing elements at the highest critical zones.
