PMI Ball Screw

Product Description

PMI Ball Screws are high-precision linear motion devices developed to deliver exceptional accuracy, efficiency, and durability in a wide range of industrial applications. Manufactured by Precision Motion Industries, Inc. (PMI), these ball screws are designed to convert rotary motion into linear motion with minimal friction, ensuring smooth performance and long service life. They are widely used in CNC machine tools, robotics, semiconductor equipment, packaging systems, and automation machinery.

PMI offers both ground ball screws for applications requiring ultra-precise positioning and rolled ball screws that provide an economical yet reliable solution for general automation. The ball screw assembly consists of a screw shaft, a precision nut, and a circulation system of hardened steel balls. This design enables high load-carrying capacity, excellent repeatability, and reduced energy loss compared to conventional lead screws.

One of the key strengths of PMI ball screws is their rigorous manufacturing process. By using advanced grinding, rolling, and heat-treatment technologies, PMI ensures tight dimensional tolerances, excellent surface finish, and superior wear resistance. They also offer various preload designs and accuracy grades, which help eliminate backlash and improve positioning precision. Additionally, options with special surface treatments and customized configurations are available to meet diverse customer requirements.

With their proven reliability, cost-effectiveness, and adaptability, PMI ball screws have become a trusted choice for industries seeking efficiency, stability, and long-term performance in demanding environments.
