Abstract
The present theoretical study is concerned with the analysis of surface roughness effects on the steady state performance of stepped circular hydrostatic thrust bearings lubricated with non-Newtonian Rabinowitsch fluids. To take the effects of surface roughness into account, Christensen theory of rough surface has been adopted. Expression for pressure gradient has been derived by means of energy integral approach. Results for film pressure, load carrying capacity and lubricant flow rate has been plotted and analysed on the basis of numerical results. Significant variations in the theoretical results of these properties have been observed.
