In this paper, the stability of a rigid rotor supported by externally pressurized gas journal bearings with a circular slot restrictor is theoretically determined by the use of the small perturbation method with respect to whirling amplitude. In the theoretical analysis, influences of the inertia forces of the gas film on the dynamic properties of this kind of bearing are investigated and theoretical results are compared with experimental data. Good agreement between the theoretical and experimental results is obtained and it is found that the effects of various factors which affect the stability of a rigid rotor supported by this kind of bearings can be accurately predicted by the present method.
