The utility model discloses a thin-wall oil cylinder casting, and belongs to the technical field of oil cylinder casting base bodies. The oil cylinder casting comprises an oil cylinder casting base body and a high-efficiency sealing mechanism, wherein the high-efficiency sealing mechanism is arranged on the surface of the oil cylinder casting base body; the efficient sealing mechanism comprises sealing rings arranged on the surface of the splicing position of the two oil cylinder casting base bodies in a sleeving mode, the bottom of the sealing ring at the top is fixedly connected with an insertion sealing ring, an annular sealing groove is formed in the top of the sealing ring at the bottom, and the insertion sealing ring is clamped into the annular sealing groove. A plurality of evenly-distributed jacking grooves are formed in the surface of the insertion sealing ring. According to the principle that like poles of magnetic force repel, the jacking piece can be driven to jack and be inserted into the inner s
