Product Overview

The ABB 3HAC039473-003 is a high-precision gearbox assembly engineered specifically for the ABB IRB 4600 industrial robot series. This component serves as a fundamental element of the robot’s kinematic chain, typically installed on Axis 3 to facilitate the vertical movement of the robot’s arm. The gearbox acts as a torque multiplier, converting the high-speed, low-torque output of the servo motor into the low-speed, high-torque force required to manipulate heavy payloads with stability and accuracy.

Manufactured to strict OEM standards, the 3HAC039473-003 ensures the structural integrity and repeatability of the robotic system. It is designed to withstand the rigorous demands of industrial automation, including continuous cyclic loading and high dynamic forces. The unit is pre-filled with high-quality lubrication and sealed to prevent contamination, ensuring long-term reliability. Replacing this component is essential for restoring the robot’s precision when issues such as backlash, excessive noise, or oil leakage occur.
