Abstract: Contact pressure has a great influence on the realiability and the life of ball bearings. However, most of the previous contact and wear model mainly focussed on the elastic model. In this paper, considering the contact between ball bearing and inner ring, both elastic and elasto-plastic contact model are established to investigate the contact behaviour on ball bearing. Three types of materials have been used to compare the contact behaviour which are bearing steel, silicon nitride and aluminium oxide. Aluminium oxide experienced highest maximum contact pressure for elastic model while silicon nitride experienced highest maximum contact pressure for elasto-plastic model. The stress contour of elastic model was elliptical shape while elasto-plastic model was elliptical shape before the material yields.
