The history of people using screws for transmission is actually not very long. Traditionally, screws have always had problems with poor positioning and easy damage. It was not until 1898 that people first tried to place steel balls between the nut and the screw to replace sliding friction with rolling friction to improve its poor positioning and easy damage.

Ball screws are ideal products for converting rotary motion into linear motion, or converting linear motion into rotary motion.

Linear guides are also called linear guides, guide rails, slides or rails.
