ABSTRACT:
Opposite side of the base section of the slide assembly are supported by two sets of ball bearings for reciprocable movement in an elongate recess formed in the slide section of the assembly. Each set of ball bearings is supported in an elongate retainer plate which extends between a pair of confronting grooves formed in the confronting surfaces of the base and slide sections at each side of the recess. Each set of ball bearings at opposite sides thereof has rolling engagement with a pair of spaced, parallel, longitudinally extending bearing rods that are mounted in each confronting groove. An elongate slot which is formed in the slide section opens at one side thereof on the bottom of one of the grooves in that section, and on the space which separates the pair of bearing rods mounted in that groove. A plurality of screws are adjustably mounted in the slide section to extend transversely across the slot, so that when the screws are adjusted the slot can be closed slightly, thereby reducing slightly the spacing between the associated pair of bearing rods, thus effecting preloading of the bearings.
