The shapes and thicknesses of the elastohydrodynamic oil films formed between a steel ball and a glass disk are measured using optical interferometry and compared with the established EHL theory. It is found that film profiles and thicknesses are markedly different from those predicted by the EHL theory, and their discrepancies depend upon the non-Newtonian response of oils and the difference in elastic moduli of contacting surfaces. As a result, it is concluded that in order to have a clearer understanding of the cause of surface failure and methods for its prevention, the EHL theory should be reconstructed by considering the solidification phenomenon of lubricating oils and pressure components parallel to the contacting surfaces.
