These gearboxes utilize high-quality metal gearbox construction with gear modules under 1mm, ensuring durability, minimal backlash, and superior torque transmission. Each gearbox stage is composed of a sun gear, planetary gears, an internal ring gear, and a carrier that enables both rotation and revolution of the gears. The result is a highly efficient, space-saving cylindrical gearbox with coaxial input and output shafts — a perfect match for micro motors in robotic, medical, and wearable technology sectors. Our gearboxes offer key advantages: Compact size with high torque output Excellent transmission efficiency Long service life under continuous use Low noise and reduced mechanical wear Keywords: 6mm metal gear motor, metal gearbox, high precision motion, dexterous hand, planetary gear motor, micro gear motor, small gearbox motor, precision micro motor, compact actuator, robotic hand motor
