Highest Precision Planetary Robotic Gearbox - GPL-V and GPL-H Series

The GPL-V (shaft) and GPL-H (hollow) are our lowest backlash (≤ 0.1 arc minute ) planetary gearboxes for horizontal and vertical robotic applications. A patented design guarantees that the backlash will not increase over the life time of the gearbox. Very high tilting rigidity results in excellent positioning accuracy with a rated 20,000 hours which is over 3x longer than comparable gearboxes in the market. The noise level of 65dB compared to 69dB of comparable models makes it ideal for MRI applications where low noise levels are critical. The efficiency is over 90% compared to 70 – 80% of other models allowing for lower power consumption which could result in choosing a smaller motor.
