BEARING BODY FOR AIR BEARING

摘要

An air bearing body has an air supply aperture opening in the center of a planar bearing surface. Shallow air circulation ducts extend spirally outwardly in the bearing surface from the air supply aperture balancing pressure in the air gap between the bearing surface and a mating bearing surface and preventing tilting forces on the bearing body. An annular air removal duct can surround the bearing surface and can be connected to a section line to contribute to the constancy of the height of the air gap between the bearing surface and a mating bearing surface.
