ABB 3HAC031958-001 Axis 2 Gearbox (Other Than Type C) – IRB4600 Series
When the axis 2 gearbox of an IRB4600 robot fails, the entire production line comes to a halt. Precision positioning is lost, repeatability degrades, and in high-throughput automotive or electronics manufacturing environments, every hour of unplanned downtime translates directly into significant financial loss. The ABB 3HAC031958-001 is the OEM-specified gearbox unit for Axis 2 on the IRB4600 series — the exact component that restores full kinematic performance and gets your robot back online with zero compromise on accuracy.
The IRB4600 is one of ABB’s most widely deployed 6-axis industrial robots, renowned for its high payload capacity (up to 60 kg), extended reach, and exceptional path accuracy in demanding applications. The 3HAC031958-001 gearbox occupies a critical position in the robot’s kinematic chain — governing the primary shoulder rotation that defines the robot’s working envelope. This part number specifically applies to IRB4600 configurations other than Type C, making correct part identification essential before ordering. As a genuine ABB spare part, it is engineered to OEM tolerances and is the benchmark against which all aftermarket alternatives are measured.

System Integration & Compatible Parts
The 3HAC031958-001 is part of the ABB IRB4600 mechanical spare parts ecosystem. When performing Axis 2 gearbox replacement, consider sourcing the following complementary components to ensure a complete and reliable repair:
- Axis 2 Motor Unit (ABB IRB4600 series)
- Gearbox sealing kit and O-rings
- ABB-specified gearbox grease (e.g., LGEP 2 or equivalent per ABB maintenance manual)
- Axis 2 brake assembly
- Relevant cable harness and connectors for Axis 2
Always cross-reference your robot’s serial number and configuration type (Type A, B, or other than Type C) against the ABB spare parts catalog (3HAC028284-001 or current edition) before ordering.
