Abstract

The invention relates to a radial bearing, comprising a housing, a housing bore extending along a bearing axis, several tilting segments that are arranged around the bearing axis in order to support a shaft and each have a radially outer bearing surface, by means of which the tilting segments are supported on a supporting surface on the housing. The radially outer bearing surface of each tilting segment and the supporting surface are arranged facing each other. Each tilting segment is movably arranged relative to the housing. The invention is characterized by the following features: a first one of the surfaces forms a first section curve with a first section plane perpendicular to the bearing axis; the first section curve is convexly curved and has a first main radius of curvature, and the second surface forms a second section curve with the section plane perpendicular to the bearing axis; the second section curve is correspondingly concavely curved and has a second main radius of curvature, wherein the magnitude of the first main radius of curvature of the first surface is smaller than the magnitude of the second main radius of curvature of the second surface; the first surface fo…
