GPL Zero-Backlash Robotic Planetary Gearbox: The New Standard in High Precision Gearboxes
GAM’s revolutionary 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 applications.
Features
- Backlash ≤ 0.1 arcmin (6 arcsec), 10x better than other precision gearboxes
- Best-in-the-market torsional rigidity for ≤ 0.6 arcmin lost motion
- Operates vibration-free for superior positional accuracy and continuous controlled 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
- Industry-accepted proven performance
- Integrated motor adapter ready to mount your motor
- Replaces direct drive motors at significant cost savings
- Exceed the performance of a cycloidal gearbox in almost every application

Gearbox Construction
The GPL Series has three stages:
- Helical pinion and gear: high ratios and quiet operation
- Planetary spur: fixed ratio
- Conical spur: lifetime zero backlash
GPL Series Models
GPL gearboxes are available in component form or with cover and integrated input pinion with motor adapter

GPL Planetary vs. Cycloidal
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.
