ABSTRACT:
A gas bearing including a support having a longitudinally extending cylindrical bore, of a predetermined diameter and an elongated generally cylindrical shaft rotatable within the bore of the shaft being of a predetermined diameter less than the diameter of the bore in the support. The outer surface of the shaft is uniquely provided with a plurality of circumferentially spaced, longitudinally extending recesses of a predetermined depth, each of which defines an elongated, generally radially outwardly extending step of a predetermined height. The outer surface of the shaft is also provided with a plurality of circumferentially spaced, longitudinally extending grooves of a predetermined depth disposed proximate the steps. At least one end of each of the grooves is in communication with a source of gas at a predetermined pressure so that as the shaft rotates the gas will be drawn into the space between the inner walls of the cylindrical bore and the outer surfaces of the shaft and will function to maintain concentricity of the shaft.
