One of the simplest way to improve the stiffness of externally pressurized gas bearings is to increase the supply pressure. The purpose of this study is to examine the possibility and practicality of high supply pressure. In the preliminary test with simple circular thrust bearings with a slot restrictor, it proves that the bearing stiffness increases almost linearly with supply pressure as predicted by the theoretical calculation. Bearing stiffness is far improved with a stepped clearance. Pneumatic hammer instability and gas flow rate are not so critical problems for the high stiffness bearings with a small clearance. The effect of deformation of the bearings by high supply pressure can not be recognized in those experiments. It is confirmed that the increase in supply pressure is the simplest and most practical way to improve the stiffness of externally pressurized gas bearings.
