Engineering Advantages
- OEM Dimensional Accuracy: Manufactured to ABB’s original tolerances — ensures correct axis-3 geometry and TCP repeatability after installation.
- Direct Drop-In Replacement: No machining or shimming required; interfaces directly with existing upper-arm casting and lower-arm pivot.
- High-Strength Alloy Construction: Designed to withstand the dynamic loads of IRB 6600’s 175–300 kg payload range.
- Dual Part-Number Coverage: 3HAC15859-3 and 3HAC050495-001 are interchangeable references — reduces procurement confusion across different BOM revisions.
- Minimizes Downtime: Stocked for immediate dispatch, reducing robot offline time versus waiting for OEM lead times.
System Architecture & Signal Flow
The Arm Extender is a passive structural component within the IRB 6600’s lower-arm assembly. It connects the axis-2 gearbox output flange to the axis-3 pivot housing, effectively extending the robot’s reach envelope by 450 mm. No electrical or signal routing passes through this component; however, correct installation torque on all fasteners is critical to maintaining the robot’s rated repeatability (±0.05 mm for IRB 6600). Refer to ABB Product Manual 3HAC026876-001 for installation procedure and torque specifications.

Technical FAQ
Q: Is 3HAC15859-3 the same as 3HAC050495-001?
A: Yes. These are two ABB part numbers referencing the same physical component across different BOM revisions. Both are valid for ordering.
Q: Does this fit the IRB 6650S (shelf-mounted variant)?
A: Compatibility depends on the specific IRB 6650S configuration. Please provide your robot’s full type designation (e.g., IRB 6650S-90/3.9) for confirmation.
Q: What is the expected service life?
A: ABB does not publish a fixed service life for this structural component. Replacement is typically triggered by visible deformation, cracking, or following a collision event. Inspect per ABB maintenance schedule 3HAC026876-001.
Q: Can you supply multiple units for a fleet overhaul?
A: Yes. Volume pricing is available for orders of 3+ units. Contact us with your fleet size and timeline.
Q: What Incoterms do you offer?
A: We support EXW, FOB Xiamen, and CIF to major ports. DDP available for select destinations — inquire at time of order.
