<p>In a rotary coupling for conducting a medium under pressure from a stationary machine part to a rotating machine part, a radially movable bushing is provided between a housing and a rotatable shaft of the rotating machine part. The radial gap between the housing and the bushing is bridged or spanned by a plurality of elastic sealing members to provide radial adjustability. A ceramic coating to minimize radial differences due to thermal expansion during frictional heating can also be provided on the shaft.</p> |
