The invention belongs to the field of ultra-precision manufacture devices, specifically relates to a radial thrust combined closed type aerostatic rotary table, and particularly relates to a high-thrust closed type aerostatic rotary table comprising a gas bearing stator, an upper thrust plate, a workpiece rotary plate, a radial bearing, an outer shell, a lower thrust bearing, a rotor rotating shaft, a sealing bottom plate, dampers, restrictors I and restrictors II. The gas bearing stator is fixedly connected to the upper end of the inner side of the outer shell. The lower end of the outer shell is fixedly connected with the sealing bottom plate. The radial bearing is connected in the gas bearing stator in an interference fit manner. The upper end and the lower end of the radial bearing arefixedly connected with the upper thrust plate and the lower thrust plate correspondingly. The upper end of the upper thrust plate is fixedly connected with the workpiece rotary plate. The lower end of the lower thrust plate is fixedly connected with the rotor rotating shaft. By means of the high-thrust closed type aerostatic rotary table, certain rigidity can be ensured while the bearing capacityof the aerostatic rotary table is improved, and use requirements of high-bearing-capacity precision manufacture devices are met.
