Wide Reduction Ratio High Torque Capacity Precision Planetary Gearbox

Name: Wide Reduction Ratio High Torque Capacity Precision Planetary Gearbox
SKU: -1

● Introduction

The HONPINE MYDR Series Precision Planetary Gearbox features a high-rigidity flange output design, combining a wide reduction ratio range, high torque capacity, and reliable transmission performance for industrial motion control applications. Available in seven frame sizes from 47 mm to 255 mm, it offers reduction ratios from 4:1 to 200:1 and rated output torque from 14 Nm to 2000 Nm, making it suitable for a wide range of servo motor systems.
With backlash of ≤2 arcmin for single-stage models and ≤4 arcmin for two-stage models, the MYDR Series delivers excellent positioning accuracy, high transmission efficiency, and long-term durability. Ideal for industrial automation, packaging machinery, assembly systems, conveyor equipment, and other OEM applications, it provides flexible, reliable power transmission for demanding motion control systems.
