This paper presents numerical solutions of static characteristics for a hybrid hydrostatic journal bearing which is able to change working fluid (air/water) according to load capacity. The numerical model considers misalignment of journal due to the offset loading. The Reynolds equation and the equilibrium equations of force and momentum were calculated simultaneously by the Newton-Raphson method. When the working fluid of the hybrid bearing was air, the shaft was declined in the loading direction and moves greatly. On other hand, When the fluid was water, the shaft was tilted in a direction perpendicular to the loading direction and traveled slightly in comparison with that in the air lubricated conditions.
