ZPBR Right-Angle Planetary Gearbox is a high-precision corner-output transmission solution developed by NUODUN for compact installation environments and advanced motion control systems.
By integrating a right-angle bevel gear input with a straight-tooth planetary gear output stage, the ZPBR series delivers excellent efficiency, low backlash, high torsional rigidity, and exceptional positional accuracy, making it ideal for servo and stepper motor applications where space is limited.

Engineered using high-strength alloy steel gears, full-gear hardening treatment, and precision grinding processes, the ZPBR gearbox maintains long-term accuracy and stability even under heavy loads and high dynamic operation.
Its lifetime grease lubrication, multiple output shaft options, and flexible motor-adaptable input flange make ZPBR a reliable choice for automation equipment, robotics, machine tools, and right-angle power transmission systems.
