In the course of this study, the run-out characteristics of the externally pressurized gas journal bearings will be analyzed theoretically to establish the fundamental concept of precision design of the gas journal bearing, with special attention paid to the relation between the run-out of the rotor and the machining errors of the bearing. For the first step of the study, the modified divergence formulation (DF) scheme to calculate the exact solution of pressure distribution in the bearing clearance is introduced in this paper, in which the conventional DF scheme is improved to be applied to the case with point-sources of supply holes. As examples of the application of this scheme, the effects of machining errors such as out-of-roundness of the rotor to the bearing characteristics are discussed.
