Abstract
The present invention is directed to a self-compensating rotary seal member adapted to be used where a vertically directed shaft passes through an aperture in a casing or the like to prevent the passage through the aperture and consequent contamination of bearings, etc. disposed to the opposite side of (e.g. below) the casing. The seal assembly is characterized by the provision of a well member having upstanding cylindrical side walls and a generally horizontal floor portion formed of material having a low coefficient of friction, the shaft having keyed thereto a high density thrust washer which is gravitationally maintained in contact with the floor portion, the thrust washer being driven with the shaft.
