A regular and reversible rotation type gas-lubricated conical grooved bearing is developed in this paper. Bearing characteristics of this new type of 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 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 mass of the stability limit) are decided. The bearing parameters, which improve both radial and axial characteristics in both directions of rotation. were decided.
