ABSTRACT:
In a mechanical seal, a rotating seal member is secured in position in a spring carrier ring by being engaged by a bayonet joint action behind the crossbars of T-shaped dimples. The rotating seal member is suitably peripherally slotted for this purpose and is urged against the crossbars by a spring loaded pressure plate. When this assembly is incorporated in a mechanical seal with a stationary seal member in running face contact with the rotating seal member the latter and the pressure plate are urged axially inwardly of the cross bars and the springs put under compression.
