PRE090 Series Precision Planetary Gearbox

Product Overview

This IP65 Precision Planetary Gearbox is designed with straight teeth and is available in three stages. At one stage, it offers a gear ratio of 3, 4, 5, 7, and 10 with a backlash lower than 10 arcmin and an efficiency higher than 97%. At two stage, this planetary reducer provides a wide range of ratios of 12, 15, 16, 20, 25, 28, 35, 40, 50, 70. Meanwhile, the efficiency is higher than 94%, and the backlash is lower than 18 arcmin. If requiring large torque, Opting for the three-stage planetary gearbox provides ratios (100, 125, 140, 175, 200, 250), ensuring minimal backlash of ≤ 25 arcmin while maintaining an efficiency of ≥ 90%. This versatile planetary reducer caters to different application needs with precision, reliability, and varying efficiency levels across its one, two, and three-stage configurations.
