Abstract
An air bearing with a rotor and a static land forming a clearance gap, the rotor including a compressible fluid supply channel to supply fluid to the bearing, and the rotor including a bearing inner race rotatably secured to the rotor, the inner race having an outer surface with a plurality of pockets opening outward and connected to a high pressure reservoir on the inner surface of the inner race through a plurality of radial extending supply channels that function as centrifugal pumps when the inner race is rotating to increase the bearing fluid pressure within the air bearing and increase the bearing stiffness. The inner race pockets extend around the full annular surface.
