ABB 3HAC021346-003 Reduction Gear – Precision Drive Unit for IRB 2400 Industrial Robot Series
When the reduction gear inside an ABB IRB 2400 robot arm fails, the consequences are immediate and costly: joint positioning errors cascade into weld seam deviations, assembly misalignments, or paint-path drift—forcing an unplanned production halt that can idle an entire manufacturing cell. Every hour of downtime on a high-throughput automotive or electronics line translates directly into scrapped output and missed delivery windows. The ABB 3HAC021346-003 reduction gear is the precision-engineered component that stands between continuous operation and that scenario, transmitting motor torque with micron-level repeatability across thousands of duty cycles.
Within the IRB 2400 platform—ABB’s workhorse six-axis robot deployed in over 100 countries for arc welding, material handling, machine tending, and assembly—the 3HAC021346-003 is the OEM-specified reduction gear for the axis drive train. It is cross-referenced under part numbers IRB24003HAC021346-003 and 3HAC17326-1, covering multiple production revisions of the IRB 2400/3 variant. As a genuine ABB spare part, it meets the same dimensional tolerances and backlash specifications as the unit installed at the factory, ensuring drop-in compatibility without recalibration risk.

System Integration & Compatible Parts
The 3HAC021346-003 reduction gear is designed to integrate directly with the ABB IRB 2400/3 axis drive assembly. When performing a reduction gear replacement, maintenance engineers typically inspect or replace the following associated components to ensure full system integrity:
- Axis servo motor (ABB IRB 2400 series)
- Motor coupling and flange hardware
- Axis brake assembly
- Gear lubricant (ABB-specified grease type per maintenance manual)
- Sealing gaskets and O-rings for the gear housing
