Planetary gear reducer MYD series

coaxialrobot flange10 - 20 Nm

Introduction
The HONPINE MYD Series precision planetary gearbox features a high-rigidity flange output design for motion-control applications requiring exceptional positioning accuracy, high torque transmission and long-term reliability. Available in seven frame sizes (47 mm–255 mm) and a wide range of reduction ratios, it suits industrial robots, CNC machines, automated lines and laser-processing equipment.

Functional description
Ultra-low backlash and high torsional rigidity provide excellent repeatability and smooth precise motion. Single-stage (P0) backlash ≤1 arcmin; two-stage (P0) ≤3 arcmin. Configurations support servo motors and robotic joints with rated output torque from 14 Nm to 2000 Nm and maximum output torque up to 3× rated.
