A lead screw combines a screw and nut, with the screw thread in direct contact with the nut thread, to transform rotary action into linear motion. The rollers, not the nut, are in direct contact with the thread in roller screws, which increases efficiency. Lead screw assemblies provide an economical solution for the transfer of rotary motion to linear motion. Berg is a pioneer in the development of lead screws; a cost effective solution to linear actuation problems. More Information... URL : https://www.caddstock.com/
