The present paper proposed a quantitative calculation of slider bearings using the analytical solutions of energy equation and of the Reynolds differential equation. The model consists in the transformation of the slider bearing pad into a journal bearing bush. The validation consists in comparing the pad's hydrodynamic parameters, calculated by means of numerical methods, with those of the proposed journal bearing, calculated analytically. The simplicity and accuracy of the method and the computing times of the order of seconds necessary for bearing estimation constitute important advantages of this model over the numerical methods.
