This paper deals with the modeling and identification of a stationary eccentricity and attitude angle for a short journal bearing with horizontal point injection port. In modeling we use the Dirac spatial delta function which allows to obtain a pressure field in a close analytical form. After using the pressure force components in the oil film, which is the addition of the Ocvirck force in the classic case and pressure force we obtain a non linear equations system with respect to stationary eccentricity and attitude angle. We found the solution equation system by obtaining the roots using the program MATHEMATICA 6 and by iteration. We developed and analyzed the work by both point pressurizing ports π/2 and 3π/2 in the journal bearing. The results are presented in tables that show the relation between eccentricity, attitude angle and the Sommerfeld´s number S.
