Abstract

A bush of a radial rotary union joint including a hollow-cylindrical main body whose inner cylindrical surface forms a sliding sealing surface divided by a peripherally extending inner groove into a first and a second sliding sealing surface and having a cylindrical outside surface which is divided by a peripherally extending outer groove into a first and a second outside surface. The wall portion separating the inner and the outer grooves has at least one bore connecting the two grooves. The first and the second outside surface can be sealed off by a stationary sealing ring in relation to a housing embracing the bush. The side surfaces of the inner groove are of the same size within a tolerance threshold of +20% and −35% as the side surfaces of the outer groove. The stationary sealing rings are positioned at an axial spacing from the axially outer end of the oppositely disposed sliding sealing surfaces corresponding to at least 40% and at most 55% of the respective axial length of the sliding sealing surfaces.
