Zero-Backlash Planetary Robotic Gearbox - GPL Series
GAM’s GPL Series Robotic Planetary Gearboxes provide the lowest backlash and high tilting rigidity for horizontal and vertical robotic and motion control applications.
Features
- With a backlash of ≤ 0.1 arcmin, the GPL Series can be considered a zero backlash gearbox
- Best-in-the-market torsional rigidity for ≤ 0.6 arcmin lost motion
- Patented design guarantees the backlash will not increase over the life time of the gearbox
- Industry-accepted proven performance
- Seven sizes with nominal output torque of 445 to 3505 Nm and ratios of 50:1 to 200:1
- Flanged solid shaft output (GPL-F) or flanged hollow shaft output (GPL-H) (up to 75 mm through hole)
- Integrated Motor Adapter Plate ready to mount your motor
- Right angle GPR available

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
