GAM GPL Zero-Backlash Robotic Planetary Gearbox

The New Standard in High Precision Gearboxes

GAM’s GPL Series Robotic Planetary Gearbox combines the lowest backlash and high tilting rigidity with vibration-free motion for smooth, controlled motion in robotics and motion control.

Why use the GPL Robotic Planetary instead of a cycloidal? The GPL Robotic Planetary exceeds the performance of a cycloidal gearbox in almost every application.

GPL Features
  • Backlash ≤ 0.1 arcmin (6 arcsec), 10x better than other precision gearboxes
  • Operates vibration-free for superior positional accuracy and control throughout the motion
  • No adjustment required: Patented design guarantees backlash will not increase over the life time of the gearbox
  • Operating life of 20,000 hours
GPL Gearbox driving trunnion

The GPL is ideal for driving the head stock in welding applications providing vibration-free, continuous coordinated motion between trunnion and robot.
