The invention relates to a rotary union for supplying and/or discharging a medium under pressure into or out of an axial cavity of a rotating machine part, comprising a union part (12), which does not rotate and is fixed relative to the device, a rotary union part (15) and with bearing means as well as sealing components, which act in a radial sealing plane between the rotary union part (15) and the union part (12) fixed relative to the device. The rotary union is characterized in that the bearing means comprise individual step bearings (13, 14), which fix the radial distance between the union part (12) fixed relative to the device and the rotary union part (15). |
