Industrial Robot Joint Solution – ABB IRB6700 Pinion RV-80 | 3HNA011788-001 / 3HAC057431-001 / 3HAC043074-001 / 3HAC043074-002
Where This Product Is Used
The ABB IRB6700 Pinion RV-80 is a precision joint-drive gear component installed in the axis gearbox assemblies of the ABB IRB6700 large-payload industrial robot series. It is specified by maintenance engineers and OEM integrators across the following application environments:
- Automotive Body-in-White (BIW) Welding Lines – Axis 1–3 gearbox replacement during scheduled overhaul on high-cycle spot-welding robots.
- Heavy Stamping & Press Tending – Restoring joint torque accuracy on IRB6700-235/2.65 and IRB6700-300/2.7 models after high-load fatigue cycles.
- Foundry & Die-Casting Cells – Replacement of worn pinion gears in harsh thermal and vibration environments.
- Palletizing & Material Handling – Maintaining repeatability (±0.05 mm) on high-throughput end-of-line palletizing stations.
- Aerospace Sub-Assembly – Precision joint restoration for drilling and fastening robots requiring tight angular accuracy.
- General MRO (Maintenance, Repair & Overhaul) – Drop-in replacement for field service teams performing gearbox rebuilds.

Why Engineers Specify This Model
- Direct OEM Cross-Reference: Part numbers 3HNA011788-001 and 3HAC057431-001 are the primary ABB service references; 3HAC043074-001 / -002 are the superseded predecessor numbers — all are interchangeable in the field.
- Cycloidal Precision: The RV-80 pinion interfaces with the Nabtesco cycloidal reducer to deliver zero-backlash torque transmission, critical for maintaining robot TCP (Tool Center Point) accuracy over millions of cycles.
- Drop-In Fit: Manufactured to OEM dimensional tolerances — no shimming or custom fitting required during gearbox reassembly.
- Reduced Downtime: Stocking this pinion enables same-shift gearbox swap, avoiding multi-day lead times on emergency OEM orders.
- Broad Variant Coverage: A single SKU covers multiple IRB6700 payload configurations, simplifying spare-parts inventory management.

Application-Specific FAQ
Q: Is this pinion compatible with both the IRB6700-200/2.60 and IRB6700-300/2.7?
A: Yes. The RV-80 pinion is shared across the IRB6700 platform for the relevant axis positions. Always verify your robot’s axis configuration against the ABB spare-parts manual (document 3HAC043074) before installation.
Q: What is the expected service life of this pinion?
A: Under normal operating conditions and correct lubrication intervals (per ABB maintenance schedule), the RV-80 pinion typically achieves 20,000–40,000 operating hours before replacement is required.
Q: Can I replace only the pinion without replacing the full RV-80 reducer?
A: In many cases, yes — if the cycloidal reducer housing and output bearings are within tolerance. A qualified ABB-certified technician should assess reducer wear before deciding on a pinion-only vs. full reducer replacement.
Q: Do you supply the matching Nabtesco RV-80 reducer?
A: Yes. Contact us with your robot serial number and axis for a matched pinion + reducer bundle quote.
Q: What is the lead time for out-of-stock units?
A: Standard lead time is 3–7 business days for restocked units. Emergency sourcing typically 1–3 business days. Contact us for real-time availability.
