The invention discloses a PDC anti-thrust ring of a slide thrust bearing, and belongs to the technical field of engineering components. The PDC anti-thrust ring of the slide thrust bearing comprises an annular base body and a PDC composite sheet, wherein a group of blind holes is uniformly arranged in the end surface of the annular base body along a circumferential direction; the PDC composite sheet is of a cylindrical structure, and composed of a diamond layer and a PDC composite sheet base layer, the PDC composite sheet base layer is assembled in the blind holes in a manner of interference fit, and an exhaust structure is arranged on the outer cylindrical surface of the PDC composite sheet base layer. According to the PDC anti-thrust ring of the slide thrust bearing, which is disclosed by the invention, because the exhaust structure is arranged on the outer cylindrical surface of the PDC composite sheet base layer, air in the blind holes can be timely and effectively discharged during a process of pressing the PDC composite sheet into the blind holes of the annular base body, thus a risk brought by ejection for the PDC composite sheet by a high-pressure gas in the blind holes under a high-temperature environment due to retention of air in the blind holes during a press-fitting process is avoided.
