Linear Guide One is designed to provide smooth, accurate, and repeatable linear motion needed for precisely guiding those delicate thinner than a human hair magnet wires onto pickup bobbins. It consists of a 1605 screw spindle and a nut integrated with rolling elements that cycle through a return mechanism. The 1605 ballscrew convert rotary motion into linear motion. This highly efficient and highly precision ground ballscrew provide high positioning accuracy and repeatability, smooth movement and long service life. Linear Guide One can be purchase without its enclosure.
