The utility model relates to the technical field of automobile hubs, in particular to a high-
corrosion-resistance automobile hub unit which comprises an outer ring, an inner ring is installed in the outer ring in a pressed mode, a
flange plate is fixedly installed at the end, away from the inner ring, of the outer ring, a plurality of steel balls are movably installed in the outer ring, and a
retainer is fixedly installed on the outer sides of the steel balls. An upper sealing piece is installed in the inner gap of the end, close to the inner ring, of the outer ring, a lower sealing piece is installed in the inner gap of the end, close to the
flange plate, of the outer ring, and a magnetic reverse gland is fixedly installed on one side of the upper sealing piece. The special lubricating
grease is coated between the magnetic
back pressure cover and the upper sealing piece, so that the sealing effect of the hub is improved, the
coating protection effect on the hub is achieved, meanwhile, the friction resistance between the magnetic
back pressure cover and the upper sealing piece is reduced, the
corrosion resistance of the hub is improved, and the service life of the hub is prolonged.
