気回転軸受装置。 Plates are attached to both end faces of the rotating shaft inserted into the bearing member, and pressurized air is blown out from the bearing member between the inner circumferential surface of the bearing member and the outer circumferential surface of the rotating shaft to support the rotating shaft without contact. In a hydrostatic air rotary bearing device, a bearing member is provided with a rotary shaft, corners formed by plate-like bodies attached to both end faces of the rotary shaft, and a plurality of grooves carved in the rotary shaft. A hydrostatic air rotary bearing device characterized in that a pressurized air supply passage and a pressurized air discharge passage are provided in a bearing member facing the convex weir of the rotating shaft.
