This paper investigates leakage from three types of shaft surfaces, finished using different manufacturing processes. The measurement of surface topography is conducted in order to determine the pertinent roughness parameters which correspond to the observed sealing performance in real practical applications. It is found that the skewness of the surface topography correlates well with the anecdotal leakage failure rate. To quantify this association, a hydrodynamic model, accounting for shaft roughness in a deterministic manner is
developed. The results from the numerical analyses confirm that the lubricant mass flow rate is
reduced in the case of negatively skewed surface height distributions, when compared with the
positively skewed profiles.
