Roller Pinion System, A Ball Screw Alternative

(Vadnais Height, Minn. - February 14, 2005) Nexen Group Inc., has announced their new Precision Roller Pinion System (RPS). This advanced technology converts rotary motion into very precise, backlash-free linear motion, while operating at high speeds over long distances. The RPS features a patented tooth design, combined with a pinion consisting of bearing-supported rollers that move smoothly along the face of each tooth, the RPS offers better performance and longer life than traditional rack and pinion or ball screw systems. Using segments of rack, the system can be configured to any distance the customer requires. The Precision Roller Pinion System maintains accurate positioning at speeds as high as 660 meters per minute (36 feet per second). Even at these high speeds, the low friction design does not create heat or wear on components - ensuring long life and low maintenance. The Nexen Precision Roller Pinion System is ideal for machine tools, gantry systems, precision servo-controlled fixtures, and large precision grinding and milling machinery - any application where high speed, high accuracy, long distances, reduced maintenance, or extended life are important. Nexen is a leading manufacturer of brakes, clutches, servo motor and linear motion control devices, torque limiters, overload protection devices, and web tension control systems for a variety of industrial applications ranging from motion control and robotics to packaging and material handling. With headquarters in Vadnais Heights, Minn., Nexen has more than 40 worldwide sales offices and more than 1,500 worldwide distributor sales outlets.
