A bearing is a machine part whose function is to support another moving machine element. It is also used to guide the motion of the element while preventing motion in the direction of applied load. Bearing takes up the radial and axial loads imposed on the moving element they carry and transmit these to the machine frame. Rolling-element bearings consist of balls or rollers positioned between raceways that conform to the shape of the rolling element. Depending on the bearing design, the loads acting on the bearing may be radial or axial loads. These loads may leads to elastic deformation at the contact between the rolling elements and the raceways. The aim of this work is to analyze the pressure distribution acting at the contact area and various stresses on the rolling elements by considering bearing parameters such as curvature and roller. The design and the analysis of bearing are carried out using Mechanical Desktop and ANSYS Work Bench respectively. The result of this study reveals that as the curvature and diameter of the roller has profound influence on the pressure and frictional stress acting at the contact area. Hence, the curvature and diameter of the roller are important parameters for effective design of any bearing. Apart from the above bearing parameters number of rollers of the bearing also have signification role in minimizing the pressure and frictional stress at the contact area.
