NUODUN ZPFR Series Right-Angle Planetary Gear Reducer combines a precision bevel gear input with a high-strength planetary output stage, delivering efficient 90° power transmission while ensuring excellent torque output and minimal positioning error. Engineered with a rigid output shaft, reinforced bearings, and precision-ground gear sets, the ZPFR series provides exceptional durability under dynamic loads, making it ideal for demanding servo motion systems.

Its compact installation depth and square-flange motor interface enable seamless integration in tight spaces such as robotic joints, CNC auxiliary axes, and automated transfer mechanisms. The internal lubrication system is fully sealed and maintenance-free, allowing for continuous industrial operation with minimal downtime. With high transmission efficiency, smooth motion, and quiet operation, the ZPFR series is an optimal choice for precision automation equipment.
