A sealing device including a seal ring (38) having an inner surface extending around a shaft (12) in a spaced relation to the shaft (12). A coating is disposed on the inner surface of the seal ring, and oil extends in the space between the coating (40) and the inner surface of the seal ring (38). The coating is of a material that is harder than that of the seal ring (38) and maintains its structural integrity and geometry during rotation of the shaft (12). <IMAGE> |
