A sealing arrangement on a rotor shaft peg of a dry-running rotation screw compressor for establishing a seal between the rotor (1) and the oil-lubricating bearing (7) of the shaft peg (3) has a labyrinth slit seal (11), located closer to the rotor, and a lip seal ring (13), located closer to the bearing, and in between an annular space (27) with ventilation opening (29) towards the bottom. The shaft peg bears a bearing race (25) made of a hardened material, which acts in cooperation with the lip sealing ring (13), and which can also extend above the area of the labyrinth slit seal (11).
