The invention contemplates a plain bearing which is guided on a prismatic rail (9) and in which the bearing elements are rollers (25 to 28) having longitudinal axes oriented parallel to the guidance direction. These rollers (25 to 28) are resiliently retained on the guided part (4), as by means of an adhesive (33), thereby permitting all rollers to have an incrementally small range of rotational displaceability. In the circumstance of force which results in twisting of the bearing portion about the guide axis, the bearing members (25, 28) can roll within small ranges on the guide (9). After eliminating such a force, the bearing returns to its basic angular position with high precision, by reason of the relatively low coefficient of rolling friction, as compared with the relatively high coefficient sliding friction which would otherwise characterize the displacement.
