A regular and reversible rotation type gas-lubricated conical grooved bearing is developed in this paper. Bearing characteristics of present new type conical bearing are analyzed by the narrow groove theory. As a result, it is clarified that the present new type conical bearing generates the axial and radial characteristics at both regular and reverse rotations and radial bearing characteristics are almost a half of conventional one directional type conical grooved bearings. The bearing parameters which maximize each bearing characteristic (the axial load capacity, the radial load capacity and the stability limit mass) are decided. The bearing parameters which improve both radial and axial characteristics at both rotations were decided.
