The invention relates to the technical field of mechanical parts, and provides a thrust wheel which comprises a thrust wheel body, a first side cover, a second side cover and a thrust wheel shaft, the thrust wheel shaft comprises a hollow shaft body, a first plug and a second plug, the hollow shaft body is a seamless steel pipe, the first plug and the second plug are plugged at the two ends of the hollow shaft body respectively, and the first plug and the second plug are connected with the thrust wheel body. The hollow shaft body is filled with lubricating oil, the outer surfaces of the two ends of the hollow shaft body are provided with grooves matched with the first side cover and the second side cover respectively, and the hollow shaft body is provided with an oil hole for the lubricating oil filled in the hollow shaft body to leak out of the outer surface of the hollow shaft body. The oil hole in the surface of the hollow shaft body is in a concave star shape, two corners of the concave star shape extend towards the two ends along the axis of the hollow shaft body to form an oil groove, the grooving width of the oil groove ranges from 2 mm to 4 mm, and the depth of the oil groove ranges from 0.8 mm to 1.2 mm. The problems that an existing thrust wheel is high in manufacturing cost and low in production profit are solved.
