A circular porous thrust pad, externally pressurized with a compressible lubricant and with predominantly axial flow in the bearing matrix, is analysed. Closed-form expressions are derived for pressure distribution, load capacity, mass flow rate and static stiffness of the bearing. It is concluded that optimum performance of the bearing is obtained when it operates close to the critical bearing number.
