A planetary gear is a gear system with a central sun gear, orbiting planet gears, and an outer ring gear. It provides high torque, compact design, and versatile gear ratios. It ensures efficient power transfer and precise motion control.

Wu Hung’s Planetary Gears deliver high torque density and efficiency through a compact sun gear, pinions, and ring gear system. Ideal for robotic arms, e-bikes, and industrial gearboxes, they offer minimal backlash and precise motion. We provide reverse engineering, motor integration, and custom modules with dimensional, hardness, and profile test documentation. Patent-compliant or NDA-based manufacturing available. Please do not hesitate to contact us for further details.
