The paper examines the effects of surface roughness on film pressure in hydrodynamic slider bearings. The estimation of the effect of surface roughness has been done on the basis of the stochastic theory, which is developed by Christensen and Tonder model. Three different types of probability density functions have been used to evaluate the effect of the longitudinal surface roughness leading to a comparison of the bearing performances. After solving the Reynolds type equation the pressure distribution is obtained. This is then used to compute the load carrying capacity. Besides, friction has also been obtained using different models. This study studies various mathematical models for estimation of pressure distribution, which may be helpful to the engineers for better design of the bearing systems. ...
