GAM GPL Zero-Backlash Robotic Gearboxes: 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 .
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 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
- Industry-accepted proven performance
- Integrated Motor Adapter Plate 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
