Industrial Robot Joint Solution – ABB IRB 6700 | 3HAC043071-003 / 3HAC060576-003 / VR3HAC043071-003
Where This Product Is Used
The ABB IRB 6700 Reduction Gear is a precision planetary/harmonic gearbox engineered for the joint axes of the ABB IRB 6700 series industrial robot — one of ABB’s highest-payload, longest-reach 6-axis platforms. Engineers specify this gearbox in the following environments:
- Automotive Body-in-White (BIW) Welding Lines – Maintains sub-millimeter TCP repeatability under continuous high-cycle spot-welding loads.
- Heavy-Payload Material Handling – Supports payloads up to 235 kg for palletizing, press-tending, and machine-tending cells.
- Foundry & Die-Casting Environments – Sealed against metal splash, coolant mist, and abrasive particulate in IP67-rated robot configurations.
- Aerospace Structural Assembly – Delivers the torque density required for drilling, riveting, and sealant-application end-effectors on large airframe sections.
- General Heavy Industry MRO – Direct OEM-spec replacement during scheduled preventive maintenance or unplanned gearbox failure events.

Why Engineers Specify This Model
- OEM Dimensional Parity – Identical bolt pattern, shaft geometry, and bearing preload to the factory-installed unit; no shimming or machining required.
- Backlash Retention – Maintains rated backlash specification over the full service life, preserving robot path accuracy in high-cycle applications.
- Dual Part-Number Coverage – 3HAC043071-003 and 3HAC060576-003 are cross-referenced OEM revisions; this listing covers both, eliminating procurement confusion.
- Reduced Downtime Risk – Stocked as a ready-to-ship unit, avoiding the 8–16 week lead times typical of direct OEM orders.
- Validated Torque Rating – Meets ABB’s published rated output torque for the applicable joint axis, ensuring compliance with robot safety and performance datasheets.

Application-Specific FAQ
Q: Is 3HAC060576-003 a direct replacement for 3HAC043071-003?
A: Yes. ABB issued 3HAC060576-003 as a revised part number for the same gearbox assembly. Both are functionally and dimensionally interchangeable on the IRB 6700 platform.
Q: Which joint axis does this gearbox serve?
A: Please confirm with your ABB IRB 6700 spare-parts catalog or contact our technical team — axis assignment can vary by robot configuration and production year.
Q: Can this gearbox be used on the IRB 6700 Foundry Prime variant?
A: The IRB 6700 Foundry Prime uses the same mechanical platform. Confirm IP rating and sealing requirements with ABB documentation before installation in foundry environments.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. Contact us for current availability.
Q: Do you provide installation support?
A: We provide part-number verification and documentation support. Physical installation should be performed by a qualified ABB-certified service engineer.
