The RPS system uses needle bearings to support the rollers that engage the teeth. This eliminates the sliding friction found in many other motion control systems, leading to an efficiency greater than 99 percent. This high efficiency means little is lost to friction, heat, and wear, providing a long life of 60,000,000 pinion revolutions or up to 36 million meters. Further key features include high speeds of up to 11 m/s (36 ft/sec), superior accuracy of +- 50 µm, zero backlash, and unlimited length, with custom lengths and modular components available.

Headquartered in the USA and with the European office based in Wemmel, Belgium, Nexen products are available from over 40 sales offices and more than 1,500 distributor outlets worldwide.
