The load capacity and stiffness of double-pad circular and rectangular porous gas bearings are analytically studied. Design curves for load capacity and stiffness versus static bearing numbers, for different supply pressures and eccentricity ratios, are given. The load capacity and stiffness of both bearings reach a maximum value at some bearing numbers and then decrease. A comparison between the load capacity and stiffness of single and double-pad gas bearings is made.
