Sango Automation Limited is a premier manufacturer of planetary servo gearboxes in China, engineered specifically for high-speed dynamic servo acceleration and exact positioning.
How the Planetary Servo Gearbox Works
Our Planetary Servo Gearbox is built specifically to pair with servo motors in high-precision motion control applications. It matches the rapid response and exact positioning of servo systems, delivering amplified torque, controlled speed reduction, and over 98% efficiency without thermal buildup.
The planetary gear design spreads load across multiple planet gears for high power density and 20,000+ hour service life.
Key Specifications
Key Performance Advantages
Engineered for high dynamic responsiveness and zero servo hunting.
Seamless Servo Compatibility
Our Planetary Servo Gearbox pairs seamlessly with servo motors. There are no awkward compatibility issues, just smooth, synchronized performance that fixes the most common headaches in precision automation.
Ultra-Low Backlash
Its ultra-low backlash eliminates annoying idle movement when changing directions, so you get consistent, repeatable positioning every time. This is critical for CNC machining, robotic assembly, and medical device production, where even small errors matter.
High Torsional Rigidity
High torsional rigidity means no gear twist under heavy loads, cutting down on vibration and keeping motion smooth and steady, even when running at high speeds.
Over 98% Transmission Efficiency
With over 98% transmission efficiency, it wastes less energy and doesn't build up excess heat.
Lower Operating Costs
Less energy waste and heat lowers your operational costs and means less time spent on maintenance.
Compact, Modular Design
Its compact, modular design makes mounting flexible. You can easily integrate it into your existing systems without expensive modifications, saving both time and labor during setup.
