High Torque Precision Planetary Gearbox for Heavy-duty Applications

Name: High Torque Precision Planetary Gearbox for Heavy-duty Applications
SKU: -1

● Introduction

The HONPINE MYB-E Series Precision Planetary Gearbox is built for medium and large industrial machinery requiring high torque, excellent load capacity, and reliable performance. Available in six frame sizes from 70 mm to 235 mm, it offers reduction ratios from 3:1 to 100:1 and rated output torque from 40 Nm to 2000 Nm. Its robust design provides high torsional rigidity, shock resistance, and efficient power transmission.
With backlash of ≤5 arcmin for single-stage models and ≤7 arcmin for two-stage models, the MYB-E Series delivers smooth motion and accurate positioning. Ideal for servo motor systems, it is widely used in packaging machinery, conveyor systems, woodworking equipment, material handling, and industrial automation applications, providing dependable and cost-effective motion control.
