Planetary gear reducer MYDR series

1000 - 5000 Nm10 - 20 Nmflange-mounted

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 systems. Offered in seven frame sizes (47 mm to 255 mm), the series provides reduction ratios from 4:1 up to 200:1 and rated output torque from 14 Nm to 2,000 Nm. Backlash options include ≤2 arcmin for applicable single-stage (P0) and ≤4 arcmin for specified two-stage configurations.

Features
