ABB IRB6700 Wrist Unit 3HAC059653-002 – Precision Wrist Assembly | IRB6700 Robot Platform
Engineering Background
The ABB IRB6700 is ABB Robotics’ flagship heavy-duty industrial robot, engineered for high-payload, high-throughput manufacturing environments. With a payload capacity of up to 300 kg and a reach of up to 3.2 m, the IRB6700 series is the backbone of automotive body-in-white lines, foundry operations, and large-scale material handling cells worldwide.
Product Positioning
The Wrist Unit (P/N 3HAC059653-002, supersedes 3HAC059653-001) is the terminal axis assembly of the IRB6700 manipulator arm. It houses axes 4–6 drive mechanics, sealing, and flange interface — directly determining TCP accuracy, repeatability, and end-effector mounting integrity. This is a safety-critical, precision-machined OEM component. Konmask.com supplies verified OEM and OEM-equivalent units with full traceability documentation.

Proven Application Environments
- Automotive Manufacturing: Body-in-white welding, press tending, and assembly lines requiring sustained high-payload TCP accuracy.
- Foundry & Die Casting: High-temperature, high-contamination environments (Foundry Plus 2 IP69K rated units available).
- Heavy Material Handling: Palletizing, machine tending, and large-part transfer with payloads up to 300 kg.
- Metal Fabrication: Arc welding, plasma cutting, and grinding cells where wrist rigidity directly impacts seam quality.
- Aerospace & Defense: Precision assembly and drilling operations requiring sub-millimeter repeatability (±0.05 mm).
- General Industrial Automation: Any IRB6700-based cell requiring scheduled or emergency wrist replacement.
Engineering Advantages
- OEM Dimensional Accuracy: Machined to ABB factory tolerances — direct drop-in replacement with zero re-calibration of robot kinematics in most cases.
- Sealed Bearing Assembly: Factory-sealed bearings prevent contamination ingress, extending MTBF in harsh environments.
- Cross-Compatible P/N: 3HAC059653-002 is the direct successor to 3HAC059653-001; both part numbers are interchangeable across all IRB6700 variants.
- Reduced Downtime: Pre-assembled and pre-lubricated unit enables rapid swap — typical field replacement time under 4 hours with standard ABB tooling.
- Traceability: Each unit supplied with OEM serial number, batch record, and Konmask inspection certificate.
System Architecture & Signal Flow
The IRB6700 wrist unit interfaces with the robot’s upper arm casting at the axis 4 gearbox output flange. Internal to the wrist, a compact bevel gear train transmits torque from axes 5 and 6 servo motors (mounted in the upper arm) through hollow shafts to the tool flange. Signal and power routing for end-effector I/O passes through the internal cable harness (dress pack) routed through the wrist hollow bore. The tool flange (ISO 9283) provides the mechanical and electrical interface for grippers, welding torches, or other EOAT.
Note: Servo motors, gearboxes, and cable harnesses are separate line items. Contact Konmask for complete wrist rebuild kits.
Sourcing & Quality Verification
- All units sourced directly from ABB authorized distributors or decommissioned OEM production lines.
- Pre-shipment inspection: dimensional check, bearing play measurement, seal integrity test, and visual inspection per Konmask QC-SOP-R001.
- Refurbished units undergo full disassembly, bearing replacement, re-lubrication, and dimensional restoration to OEM spec.
- Counterfeit prevention: Konmask does not source from unauthorized secondary markets. All units include OEM labeling and traceable batch documentation.
- Export compliance: Units shipped with commercial invoice, packing list, and HS code 8479.89 declaration for customs clearance.

Technical FAQ
Q: Is 3HAC059653-002 backward compatible with robots currently running 3HAC059653-001?
A: Yes. ABB issued 3HAC059653-002 as a direct supersession of 3HAC059653-001. The mounting interface, gear ratios, and flange dimensions are identical. No software or calibration changes are required.
Q: Can this wrist unit be used on IRB6700 Foundry Plus 2 variants?
A: The standard unit (IP67) is not rated for Foundry Plus 2 environments. Please specify your robot variant at inquiry — Konmask can supply the IP69K-rated Foundry Plus 2 wrist assembly.
Q: What is the recommended replacement interval?
A: ABB recommends wrist inspection at every 20,000-hour service interval. Replacement is triggered by bearing play exceeding 0.1 mm, abnormal noise, or seal failure. Refer to ABB Product Manual 3HAC044266-001 for full maintenance schedule.
Q: Do you provide installation and commissioning support?
A: Yes. Konmask provides remote technical guidance. For on-site support in mainland China, contact us to arrange an ABB-certified field engineer.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit. Volume pricing available for orders of 3+ units.
