Roller Pinion Gear System for Rotary Motion Control

Nexen offers an advanced new technology that revolutionizes rotary motion. The Roller Pinion Gear system (RPG) provides zero backlash, very high positional accuracy, 99% efficiency, high rigidity, 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.

The Roller Pinion System features a rack with patented tooth design combined with a pinion consisting of bearing supported rollers to ensure precision and reduce maintenance. Offering better performance and longer life than traditional rack and pinion or ball screw systems, the Nexen Precision Roller Pinion System has sizes ideal for a variety of linear motion applications.

Accurate Positioning

The RPG system features an innovative ring gear and roller pinion technology that provides extremely accurate positioning. The Roller Pinion Gear system also offers backlash-free performance in both directions by maintaining opposing contact with two or more teeth at all times.

High Speed Capability

The RPG system maintains accurate positioning at peripheral 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.

Unlimited Diameters

Nexen can provide solid ring gears up to one meter in diameter. Ring gears larger than this become segmented and can be virtually any diameter. Arc segments can also be
provided.
