A face seal device for use with components rotating at a high rotational speed includes a non-rotating face seal ring ( ) and a rotary face seal ring ( ). The rotary face seal ring is mounted in a loose fit for common rotation with a rotating component and includes a sealing face ( ) which, in operation, is essentially radially aligned for cooperation with an opposite sealing face ( ) of the non-rotating face seal ring. A heavy-mass-contributing element ( ) is arranged to rotate in common with the rotating component and engages a portion of the rotary face seal ring. The center of gravity of the heavy-mass-contributing element is axially spaced from that of the rotary face seal ring, whereby, in operation, a torque directed towards the non-rotating face seal ring is applied to the rotary face seal ring. This torque arises from the centrifugal forces that correspond to the mass-contributing element and the spacing between the centers of gravity.
