VRL 090 Frame

The VRL Series is the all-rounder in the planetary gear reducer marketplace. With helical gearing, robust internal construction, smooth operation and high torque density, the VRL is truly best-in-class. 5 arc-min backlash allows the VRL to be applied to a wide range of applications where accuracy and dynamics are in play, but cost is of concern.
