Harmonic Drive is your one-stop headquarters for miniature speed reducer products designed for applications requiring smaller, space-saving components. These devices decrease a motor's rotational speed while increasing output torque and generating zero backlash. Options include mini compact gearheads and miniature actuators. Our mini gearheads, also referred to as miniature gearboxes, are the ideal choice in confined areas where maximum precision is essential. Key features include a compact four-point contact ball bearing mounted to the main shaft, outline dimensions up to 13 mm and precision-matched motors and encoders. Our compact gearboxes come in five sizes, four ratios and flange or shaft outputs.
