ABSTRACT:
A face seal device for sealing a shaft relative to a casing includes a pair of co-operating seal rings, one of said seal rings serving for non-rotational mounting on the casing and the other for common rotation with the shaft. The seal rings include bores through which the shaft is extended when in operation, and which are held in radial alignment with the shaft by a mounting member which can be inserted in the bores and withdrawn from engagement with the bores by an axial force which can be applied to the mounting member. The seal rings are held in the operational positional relationship of each other by a pair of axially spaced axial stops on the mounting member between which the seal rings are disposed. One of the stops engages the non-rotational seal ring and the other the rotating seal ring. The axial stop engaging the rotating seal ring is held radially resiliently.
