Zero-Backlash Precision for Robotic Motion Control
AIMRSE precision robot gearboxes deliver exceptional torque density, positioning accuracy, and torsional rigidity for the most demanding automation applications. Our portfolio includes high-precision RV gearboxes and harmonic drive strain wave gears engineered for articulated robots, collaborative robots (Cobots), CNC rotary axes, and semiconductor manufacturing equipment. With backlash as low as 0.5 arc-min and reduction ratios up to 200:1, we enable smooth, repeatable motion in compact form factors.
Every gearbox undergoes rigorous testing for transmission error, lost motion, and torsional stiffness. We offer standard and custom input shaft configurations, integrated motor mounting interfaces, and sealed designs for food-grade or cleanroom environments. Whether you're designing a six-axis industrial robot or a high-speed delta picker, our application engineers will help you select the optimal precision gearbox solution.

Typical Applications by Industry
AIMRSE precision gearboxes power critical motion axes across automation and robotics.

Industrial Robotics
RV gearboxes for 6-axis articulated robots, welding robots, palletizers, and heavy payload handling.

Collaborative Robots (Cobots)

Medical & Surgical Robotics
Compact, low-backlash harmonic gearboxes for surgical robots, diagnostic imaging, and patient positioning.

AGV / AMR & Logistics
Compact planetary and harmonic gearboxes for autonomous mobile robot wheel drives and lifting actuators.
Performance Validation & Field-Proven Reliability
We standardized on AIMRSE RV gearboxes for the major axes of our high-speed palletizing robots. Over 20,000 operating hours, the backlash remains within 0.5 arc-min without any adjustment. The gearboxes run cooler and quieter than previous suppliers, which has been a key selling point for our end customers.
Our Cobot joints require extremely smooth torque output to achieve safe force limiting. Switching to AIMRSE harmonic gearboxes reduced our joint torque ripple by over 30% and improved the overall haptic response. The custom input shaft design simplified our motor integration and reduced assembly time.
