ABSTRACT:
To support machinery subject to dynamic vibration in operation, such as sewing machines and the like, on a platform which is movable longitudinally with respect to a post (12), a carriage (14) has at least three or four rollers located thereon of essentially double-conical shape, engaging circular guide surfaces (24) formed on the post. The post (12) preferably is a hollow extruded aluminum rail (12), and the conical portions (46) of the roller form lateral portions having, in cross section, a concave contour which overlaps a projected contour of the guide surfaces of the rails adjacent the terminal ends. The rollers are of elastically deformable material so that, upon engagement with the rail, the terminal end portions will compress and place the guide surfaces under compressive force which is accepted by the rollers, acting in the direction parallel to the shaft axis of the rollers. The center portion of the rail (12) between the guide surfaces (24) where engaged by the roller (42) is relieved (28) so that the central portion (44) of the roller does not contact the post, to permit the compressive force to be fully effective.
