Roller pinion system
Precision roller pinion system is an alternative to precision ballscrews, converting rotary motion into precise, backlash-free linear motion.
Features & benefits
Bearing-supported rollers mesh with optimized tooth profiles, achieving smooth, trouble-free motion
Accurate positioning speeds to 660 m/min
Low friction design minimizes heat and wear
Segments of rack allow the system to be configured for any length
