Nexen offers an advanced technology in linear motion.
The Roller Pinion System (RPS) provides zero backlash, high positional accuracy, huge length, high speeds, good 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.
The Roller Pinion System design eliminates many of the limitations of current linear drive systems like:
Ball screws: Limited by critical speed, maximum speed, cumulative error, vibration, thermal expansion, supplemental cooling, noise, low efficiency, maintenance, and life
Traditional rack and pinion: Limited by low accuracy and speed, backlash, tooth fatigue, noise, high cost of dual and split pinion systems, high maintenance, and short life
Belt drives: Limited by low accuracy, backlash, low load capacity, short lengths, belt stretch, and low rigidity
Linear motors: Limited by low load capacity, high cost, strong magnetic fields, and liquid cooling
The Roller Pinion System is available from Norman G Clark.
