The three dimensional EHL problem between two elastic rollers with finite width is analized numerically using finite element method and the Newton-Raphson method. The effects of side leakage flow on pressure distribution and fluid film profile are considered and the following results are obtained. (1) Near the center line of roller, pressure distribution and fluid film shapes are resemble to that of the infinite width cae. (2) The maximum pressure appears near the side edge of roller. (3) The minimum film thickness is smaller than that of obtained by infinite width roller model. The convergency is quite severe and the results obtained in this study are limited to several cases. Further numerical calculations are needed to analyze the finite width EHL problem.
