The utility model relates to sealing detection equipment, in particular to an air tightness test device for a hub bearing sealing ring, and belongs to the field of sealing detection. The technical problem to be solved by the utility model is to provide an air tightness test device for a hub bearing sealing ring so as to improve the detection precision of the sealing performance of a hub bearing. The utility model relates to an air tightness test device for a hub bearing sealing ring. The device comprises a sealing plate, a pre-tightening block and an air pump, a to-be-tested bearing is locatedbetween the sealing plate and the pre-tightening block, the sealing plate, the pre-tightening block and the to-be-tested bearing form a sealing cavity, the air pump inflates the sealing cavity, the whole device is immersed in liquid, the air pump inflates the sealing cavity, and whether the sealing performance of the hub bearing is qualified or not can be judged by observing whether bubbles emerge at a hub bearing sealin
