An arrangement of a shaft with a slip-ring seal mounted thereon is disclosed. The slip-ring seal ( 3 ) comprises a pair of cooperating slip rings ( 4,5 ), the sealing faces of which define a sealing gap ( 6 ) between them. One of the slip rings is mounted on the shaft ( 2 ) with torque transmission from a drive element ( 9 ) mounted on the shaft, whilst the other slip ring is provided for fixed mounting on a stationary component. The arrangement is characterised in that the drive element ( 9 ) comprises a tubular drive housing ( 11 ), extending over the external circumference of the slip ring ( 4 ) with a radial gap ( 12 ) and a passage ( 13 ) for introduction of a flow medium is provided, opening out at one end in a chamber (A), defined by the drive housing ( 11 ), which drains out through the radial gap ( 12 ), whereby the radial gap forms a flow path for the flow medium which terminates at or near the sealing gap ( 6 ).
