Among other things, it discloses in one embodiment a device for supporting a cylinder in a side frame, wherein an inner ring of a radial bearing is provided for receiving a pin of the cylinder, which is mounted on rolling elements in an intermediate ring, which in turn is mounted via rolling elements in an outer ring. In order to enable a pressure on / off adjusting movement, the inner ring is arranged eccentrically with respect to the circumferential line of the intermediate ring. So that the radial bearing can expand unhindered when heated, it is arranged in a region of the intermediate ring, which protrudes from a frame alignment of the side frame to the side of the cylinder. The storage between the outer and intermediate ring is arranged axially offset in the frame alignment, so that the radial bearing can expand when heated, without being clamped by the outer ring.
