This paper describes the effect of the shape of the air supply area in a circular aerostatic porous thrust bearing on the bearing characteristics. In the bearing design, the porous material with a smaller thickness has been used in order to reduce the bearing size. Reducing the thickness of the porous material results in decreasing the strength of the bearing surface. Especially when the diameter of porous material is large, it will be difficult to supply the air through the whole back area of porous material, considering the strength and the deformation of porous material. Therefore, the groove supply and the hole supply are adopted to avoid the deformation of the bearing surface. Furthermore, the bearing characteristics of the bearings with these supply methods are clarifined theoretically and experimentally.
