Tapered roller bearings used in railcar application are frequently subjected to severe loading conditions and environment. If environmental conditions are ignored, the bearing life and failure is solely dependent on surface and sub-surface stresses arise in the bearing surface. In this research Hertzian contact was modeled for tapered roller bearing by using commercially available Finite Element packages. Hertzian contact stresses arises when two non-planer bodies come in contact under the influence of force. High localized stresses occur near area of contact of bodies and thus it is important to evaluate these stresses during designing of tapered roller bearings. For this research, analysis was carried out for two different bearing materials viz. steel bearing & multi layered carbide bearing. The models were preprocessed by using ABAQUS and results of both materials were studied and compared. From the obtained results, feasibility of replacing steel bearing with carbide layered bearing was studied as carbide layered bearing were economical to manufacture.
