A tilting-segment radial bearing for a single-shaft turbomachine is provided, having a support ring, a tilting-segment mounting and a tilting segment, which in the installed state of the tilting-segment radial bearing is supported on the support ring such as to be seated on top and be radially displaceable by the tilting-segment mounting. The mounting has a preload device, by means of which the tilting segment is preloaded in the direction toward the shaft of the single-shaft turbomachine when the operating rotational speed of the single-shaft turbomachine is above a predetermined tilting-segment preload rotational speed, such that the tilting segment can be radially moved without preload when the operating rotational speed of the single-shaft turbomachine is below the tilting-segment preload rotational speed.
