According to the magnetic fluid model incorporating with the stochastic model, the performance characteristics of a magnetic fluid lubricated short journal bearing with rough surfaces are investigated. A stochastic magnetic fluid based Reynolds equation has been derived. Analytical expressions for the bearing performances are also obtained. From the results obtained, the effects of longitudinal roughness patterns result in an increased load capacity as well as a reduced friction parameter and attitude angle. The amounts of increased load and reduced friction parameter are more pronounced for the bearing operating at higher values of the volume concentration, magnetic parameter, roughness parameter and eccentricity ratio.
