To solve the three-segment loop-like damage of sleeve under rolling load case, to quantitatively analyze bearing failure mechanism, a mathematical model of oil-film bearing for producing the 3-D contact pressure and shear stress distribution between sleeve and roll neck was developed by 3D elastic contact boundary element method. Some programs for automatically creating 3-D surface grid model have been developed to check data and display deformation, as well as to plot the deformation fields of roller and sleeve. Analytical results provide an effective way to decrease wear and adhesive damage of sleeve, and help to increase the load capacity of oil-film bearing and service life as well.
