Wemmel, Belgium, March 2017. Nexen Group, Inc. introduces a stainless steel version of its patented precision roller pinion system RPS. The RPS engages two teeth simultaneously to achieve superior accuracy with zero backlash at any length. The system is quiet and efficient. Stainless steel makes it extremely corrosion resistant, with a long life of up to 36 million meters. Nexen’s RPS provides a low maintenance, durable alternative to rack and pinion, ball screw and belt drive technology. The RPS is used for a wide range of applications including laser and plasma cutting machines and gantry machining centers.
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.
Nexen produces roller pinion systems, industrial brakes, clutches, torque limiters, overload protection devices and control systems. The company holds 120 US and international patents. 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.
