The invention belongs to the technical field of bearing manufacturing, and provides a rear retainer ring of a wagon rolling bearing. The rear retainer ring (1) is provided with a rear retainer body (1-1). The inner surface of the rear retainer body (1-1) is an arc surface matched with the outer wall surface of a shaft shoulder. One side end face of the rear retainer body (1-1) is provided with an annular notch. One end of a sealing ring (1-2) is located in the annular notch in the rear retainer body (1-1), and the other end of the sealing ring (1-2) is arranged on a dust guard seat (4) in a sleeving mode. The inner diameter surface I (12) of the sealing ring is in interference fit with the outer diameter surface (14) of the dust guard seat. The inner diameter surface I (12) of the sealing ring is provided with a conical surface, and the conical surface is of a structure gradually drawing down inwards from the end, away from the rear retainer body, of the sealing ring. According to the rear retainer ring, axial movement, caused by deflection of a main shaft and a shaft neck, of the rear retainer ring is reduced, reutilization of the rear retainer ring is achieved, and the overhaul cost is lowered.
