In the various production phases of the bearing rollers, multiple collisions occur, which lead to defects in the finite product. These small defects (dents) have a negative effect during exploitation: they can be the initiation point in fissure spreads which lead to vibrations and a high level of noise. Thus, the bearing is degrading. For the current study various analytical calculations have been performed in order to highlight the energy transfer between the two elements. They have been validated through the finite element method (FEM).The results obtained emphasize that critical areas may appear in the test piece. In those areas the equivalent stress is close to the yield point of the material used in bearing rollers manufacturing.
