A carrier is suspended and moves on two shafts. The carrier includes a plurality of sealed roller bearings which form openings approximately equal to the dimensions of the shaft. One or more of the bearings is mounted on a leaf spring to provide a predetermined contact pressure between the bearings and the shaft. In addition, damping elements may be substituted for one or more of the sealed roller bearings to minimize interference from vibrations.
