Abstract
In a stern seal and bearing assembly for the stern shaft of a ship there is an oil seal assembly at the outboard end of the bearing and a sea water seal (preferably a face seal) axially spaced from it, with a drain from the space between the two, and the oil seal assembly comprises a pair of lip seals directed towards each other with a drain from the space between them. The oil supply to the bearing can be at low pressure, for example simply the static head from a tank slightly above the level of the bearing, and the last-mentioned drain may have a swan neck above the oil level.
