This study presents an analysis of eccentricity ratio of dynamically loaded-journal bearing using mobility method. Computational calculation has been done by using solution of Ocvirk and Goenka's curve fit. And we investigate influences of design parameters on bearing load and eccentricity ratio.(maximum film pressure, min. oil film thickness, and radial clearance) and calculate the absolute viscosity of oil film with the relation of pressure-viscosity and temperature-viscosity. The results show that we must consider variation of temperature and pressure on the analysis of oil film lubrication.
