The 72mm Planetary Gearbox features a compact metal planetary gear design with an allowable torque range of 15N.m to 85N.m. It supports 12V/24V configurations and offers flexible reduction ratios from 3:1 to hundreds:1 through single or multi-stage gearing. Its compact and lightweight design is ideal for space-constrained motion systems.
