An arrangement at rotating shafts with a wheel fixedly mounted to the shaft, which wheel rotates in a housing surrounding the wheel, an essentially pipe-shaped element surrounding the shaft, an with essentially axially sealing surface provided sealing device between the pipe-shaped element and the wheel and a passage in the housing for the shaft with a sealing device, which seals against the pipe-shaped element. There is mounted a fastening device on the shaft for axial displacement of the pipe-shaped element in order to cause a sealing effect by means of the sealing device between the pipe-shaped element and the wheel. The fastening device is fixed in sealing position by a locking device.
