Automobile ball bearings experience severe contact stresses during vehicle manoeuvring near the contact with inner and outer races. The accurate prediction of the contact stresses and life estimation of ball bearings has always been challenging, following the complex nature of the contact involved and the resulting Rolling Contact Fatigue. The present paper describes the finite element analysis performed using a general finite element code, ABAQUS, on an automobile wheel hub ball bearings to predict accurate contact stresses, bearing loads and thereby life estimation of bearings in the form of ISO 281 (1990) life. Lundberg and Palmgren method is employed for the determination of the bearing life. RomaxDESIGNER, a bearing design software, is also employed to consider the various bearing life adjustment factors to be applied on the determined ISO life. Also an attempt has been made to develop a relation between the contact stress and the bearing life for the hub assembly ball bearings.
