Bearing is an important part of a moving machine which is used for relative motion between the contact surfaces. Wear and tear of bearing is a common problem due to friction between the moving parts. A lot of researchers have done work for improving the life of the bearing. In the present work, traditionally used ball bearing has been modeled and analysed using FEM. Parameters such as Equivalent (Von-Misses) Stress, Maximum Principal Stress, Equivalent Elastic Strain, Maximum Shear Stress and Total Deformation have been found out. Analysis has also been carried for finding out the effect of material of bearing: steel, Structural Steel, Si3N4 and SiC on its performance along with elastic strain, stiffness and total deformation for various materials. It can be concluded that the Deformation and Elastic Strain induced in the SiC is less than the steel, structural steel and Si3N4 for the present investigation and the Stiffness of SiC is maximum as compared to steel, structural steel and Si3N4 hence SiC is the best material for ball bearing.
