Zusammenfassung:A rotary union for a tire inflation system includes an axle housing and a wheel axle rotatably mounted in the axle housing. The wheel axle has a flange for attachment of a wheel rim. The wheel axle is received by a passage socket that is connected for conjoint rotation to the wheel axle and supported by a radial bearing relative to a bearing seat within the axle housing. A compressed air duct is disposed inside a cylindrical wall of the passage socket such that the compressed air duct is connected at one end to a pressure connector mounted on the axle housing and at the other end to a tire connector mounted on the passage socket. The passage socket is sealed rotationally movably with respect to an adjacent inner side of the axle housing such that an enclosed chamber is formed between the pressure connector and the compressed air duct.
