Huxing Precision Robot Joint Reducers: High Torque, Low Backlash, Designed Specifically 

for Humanoid Robots


Features include:


✅ Ultra-High Precision Operation: Premium models have a backlash as low as 30 arcseconds

 while standard models are ≤1 arcminute, ensuring lag-free movement and adapting 

to various delicate movements of humanoid robots.


✅ High Torque Density, Lightweight Design: Torque density up to 120 N·m/kg

compact size, perfectly fitting into narrow joint spaces such as the shoulder, elbow

hip, knee, and wrist.


✅ Impact Resistant and Long Service Life: Utilizes alloy steel with enhanced heat treatment

capable of withstanding dynamic impacts such as walking and jumping

with a rated service life exceeding 10,000 hours.


✅ Full Product Range: Complete with three major series: Harmonic, Precision Planetary

and RV, adaptable to everything from light-load hand joints to heavy-load lower limb 

and base joints.


✅ Integrated Modular Solution: Integrates reducer + motor + encoder + driver into 

a complete joint module, increasing overall integration efficiency by 50%.


✅ High Cost-Performance Ratio: Performance comparable to top-tier imported products

priced at only 50%-70% of imported models, facilitating cost reduction

and mass production of humanoid robots.


✅ Customization Supported, Efficient Delivery: Non-standard customized solutions 

can be provided quickly, with delivery cycles 50% shorter than imported brands.
