Nexen Group: Nexen Group: Ball screw alternative

Nexen Group has introduced the Precision Roller Pinion System (RPS), with advanced technology that converts rotary motion into precise, backlash-free linear motion, while operating at high speeds or over long distances.
FILED IN:  Controls  > Motors  > Linear

Features a patented tooth design combined with a pinion consisting of bearing-supported rollers that move smoothly along the face of each tooth. Said to offer better performance and longer life than traditional rack-and-pinion or ball-screw systems the RPS can be configured to any distance required using segments of rack. RPS maintains accurate positioning at speeds as high as 36’/sec and even at high speeds the low-friction design does not create heat or wear on components. Ideal for machine tools gantry systems and precision servo-controlled fixtures.
