In this study, the subsurface stress field beneath the roller by fluid film pressure working on the roller surface has been calculated by using the rectangular patch solution. Main purpose of this study in view of engineering is to prove the validity of the profiling roller presented by Koo et al. Koo et al. obtained the fluid film pressure by EHL analysis of earn-roller mechanism. To prove the advantage of this study, we compared Koo's profiling with the existing Dub-off profiling roller. To obtain the subsurface stress field created by normal force, namely, fluid film pressure, Love's solution is used.
