NUODUN ZPDR Series Flange-Mount Right-Angle Planetary Gear Reducer combines a 90-degree bevel-gear structure with a precision planetary gear system to deliver both compact installation and high mechanical performance. Designed for modern servo systems, the ZPDR series features rigid flange mounting, ensuring excellent positioning stability and vibration resistance in high-load, high-precision applications.

The reducer offers superior torque capacity and extremely low backlash for highly accurate motion control. Its sealed lubrication system provides long-term maintenance-free operation, while optimized helical gear design ensures smooth transmission, low noise, and high efficiency. The compact right-angle layout allows installation in tight spaces, making it ideal for robotic joints, indexing mechanisms, packaging equipment, and compact automation modules.
