ABSTRACT:
A linear slider may be formed essentially from a block and two parallel shafts mounted through the block. The first shaft runs on coaxial bushings, while the second shaft runs in a single floating bushing. The floating bushing slides perpendicular to the first shaft. The first and second shafts are then coupled to slide as a pair. The first shaft is then free to run back and forth. The second shaft also runs back and forth, but prevents the first shaft from rotating, without binding between the two shafts. Seals and a lubrication system are added to assure a smooth, durable action.
