ABSTRACT:
A lathe bed scanner having a lead screw that is substantially prevented from axial movement, the scanner comprises a first magnet integrally attached to the lead screw. A second magnet disposed opposite said first magnet for attracting the first magnet, which attraction permits the first magnet to prevent axial movement of the lead screw. A ball bearing disposed between both the first magnet and the second magnet for permitting the lead screw to rotate while maintaining the prevention of axial movement.
