Precision Roller Pinion System
Premium and Standard Models
Nexen offers an advanced new technology that revolutionizes
linear motion. The Roller Pinion System (RPS) provides zero backlash, very high positional accuracy, unlimited length, very high speeds, 99% efficiency, high rigidity, low noise, low maintenance, corrosion resistance, and long life. This opens up new design possibilities and provides the capability to achieve much higher levels of performance in machine designs. Precision Operation Maintains Accurate Positioning The RPS line features an innovative rack and roller pinion technology that provides extremely accurate positioning. This design eliminates the cumulative error and thermal expansion error problems experienced with
ball screw manufacturers systems. The Roller Pinion System also offers backlash-free performance in both directions by maintaining opposing contact with two or more teeth at all times. This design eliminates the costly and complex split and dual pinion systems required by most traditional
rack and pinion systems to achieve zero backlash. Patented Tooth Design Ensures Quiet Operation The RPS line is designed with
suppliers of bearing supported rollers that move smoothly along the face of each tooth. This reduces noise levels often associated with other linear motion systems like tooth slap or ball return noise. Segmented Rack Provides Easy Integration and Unlimited Travel Nexen offers the rack in segmented lengths, making it easy to accommodate your application requirements. Supplied in meter and half meter increments, length can also be custom cut as required. The basic system is comprised of just two parts, a rack and roller, making it easy to adapt to any application. Rugged Design Capable of High Speeds The Roller Pinion System maintains accurate positioning at speeds as high as 11 m/sec (36.1 ft/sec). Even at these speeds, the extremely-low friction design does not create heat or wear on components.
