Zusammenfassung:	A dynamic pressure bearing structure with double beveled edges is provided. The dynamic pressure bearing structure includes a bearing body, a shaft hole, and at least one oil guiding groove group. The shaft hole is disposed inside the bearing body and passes through two ends of the bearing body. The oil guiding groove group is arranged on an inner wall of the shaft hole. Two beveled edge portions are disposed on outer walls of the bearing body and forms an air escape structure. An outer diameter of the bearing body, an inner diameter of the shaft hole, and a height of the bearing body form an optimized size, with a thinnest position having a thickness being greater than or equal to 0.01 mm. The dynamic pressure bearing structure is manufactured using a metal cutting process or a powder metallurgy process.
