ABSTRACT:
The rotatable seal ring of a mechanical seal is attached to a plain shaft by a grip ring and a housing that includes a disc spring. The rotatable seal ring is pressed against the non-rotatable ring by the disc spring, the compression of which is uniquely controlled by the depth of a recess formed in the housing to receive the grip ring.
