ABB 3HAC043134-001 is the Type C axis-2 gearbox for the IRB 2600 robot. It reduces motor speed and carries axis-2 torque between the drive motor and lower-arm structure, where the gearbox supports a major share of the robot arm load.

Mounting faces, input coupling, output connection, bearings, seals and lubricant form the working boundary of ABB 3HAC043134-001. The Type C execution and complete article number must match the robot record because adjacent IRB 2600 drivetrain versions cannot be inferred from appearance alone.

Before ABB 3HAC043134-001 is released, the upper structure is supported in the prescribed service pose. Reassembly is followed by calibration, low-speed axis-2 movement and checks for abnormal current, noise, backlash, leakage and restored position.
