The invention discloses an air floatation thrust bearing based on axial dense ball suction loading, and belongs to the technical field of gas bearings and gas lubrication. The device comprises an air floating shaft, an air floating sleeve, a thrust plate and a suction loading device, wherein the air floating shaft is in a T shape, the air floating shaft and the thrust plate are installed on the two sides of the air floating sleeve, and a steel ball in a retainer is located between the air floating shaft and the air floating sleeve so that the air floating shaft and the air floating sleeve can be in interference fit. The rotation precision is improved by utilizing the air bearing, the radial run-out of the bearing is reduced, and meanwhile, the axial bearing, the rigidity and the overall stability of the main shaft are improved by utilizing a dense ball shaft system. According to the invention, the dense ball shaft system is combined with an air floatation bearing technology, and the air floatation thrust bear
