Abstract
A seal assembly primarily for use with the stern bearing of a ship comprises inner and outer face seal elements mounted on a rubber body for rotation with the propeller shaft. Any oil from the bearing which leaks past the inner element, or sea water which leaks past the outer element, enters a void space formed by pockets in the rubber body. These pockets are separated by inclined vanes which act as a centrifugal pump to expel the leakage material through a passage in a seat for the seals. The assembly can also be used in other applications where the leakage material is corrosive or is likely to cause blockages.
