Analytical solutions of the Reynolds equation for the porous journal bearings are not generally achievable and numerical methods must be involved. This paper presents an approximate mathematical model for the one-dimensional lubrication equation for the infinitely long porous journal bearing, obtaining a good agreement over the ranges of operating conditions of this tribological component.
