A theoretical estimate is made to evaluate performance characteristics in terms of steady state and stability of two-layered externally pressurized porous gas journal bearings. Assuming only radial flow in the porous medium and considering two-dimensional flow in the bearing clearance, basic equations are solved to find load capacity and stability margin. It has been observed that a two-layered bearing gives higher stability when compared with a single-layered one.
