This investigation tries to examine the effect of magnetic fluid lubrication on the behaviour of a longitudinally rough rotating circular step bearing resorting to the stochastic model of Christensen and Tonder. The magnetic fluid flow model given by Neuringer Rosensweig is used here. The pressure distribution is obtained by solving the Reynolds type equation associated with the bearing system. Then the load carrying capacity is calculated. The graphical results presented here establish that the magnetic fluid lubrication offers significant help to the longitudinal roughness pattern to enhance the performance of the bearing system. This assistance of magnetic fluid became more favorable when the plates rotate in opposite direction.
