High Precision Servo Reducer
DETAILS:
Sango High Precision Servo Reducers are engineered for high-dynamic motion control systems requiring ultra-low backlash (<1 arcmin) and superior torsional stiffness.
Featuring carburized ground helical gear teeth, single-piece planet carriers, and ISO 9409 robotic mounting flanges, these reducers excel in CNC machine tools, semiconductor wafer handling, and medical surgical robotics.
Sango Automation Limited is an industry-leading manufacturer of high-precision servo planetary reducers in China. Designed for demanding automated machinery, our ultra-low backlash gearboxes deliver whisper-quiet operation, unmatched positioning accuracy, and zero lost motion.
Product Overview
High-precision servo reducers are specifically developed for high-acceleration, zero-backlash motion control applications where micro-positioning accuracy and short settling times are critical.
Utilizing premium alloy steel gears carburized and ground to DIN 5 flank accuracy, Sango precision reducers achieve P0 micro-backlash (<1 arcmin) while maintaining high torsional rigidity and ≥97% single-stage transmission efficiency.
Available in round flange, square flange, and ISO 9409 robotic mounting interfaces, Sango high-precision reducers provide seamless compatibility with all AC servo motors.
How It Works
DIN 5 Micro-Ground Helical Teeth
Carburized alloy steel helical gears ground to DIN 5 quality guarantee backlash under 1 arcminute and whisper-quiet noise levels (<56 dB).
Single-Piece Planet Carrier Cage
Dual-supported planet carrier cage machined from a single solid forging maximizes torsional stiffness under heavy reversing torque.
ISO 9409 Robotic Output Flange
Direct bolt-on flange output interfaces directly with robot arms, pinion gears, and indexing carousels without intermediate couplings.
Dynamic Balanced Motor Clamp
Dynamic balanced split-collar clamping mechanism withstands high input speeds up to 10,000 RPM without vibration.
