ABB 3HAC17327-1 / 3HAC037835-001 / 3HAC049629-001 – Process Wrist | IRB2400 / IRB660 / IRB6600 / IRB6650 / IRB1520ID / IRB1200 Platform
Engineering Background: The ABB Process Wrist is a precision-engineered end-of-arm mechanical assembly designed for ABB’s industrial robot series. It serves as the critical interface between the robot arm and the end-effector (tool), transmitting torque, motion, and process media (cables, hoses) with high repeatability. The three part numbers — 3HAC17327-1, 3HAC037835-001, and 3HAC049629-001 — are the OEM-designated wrist units for the IRB2400, IRB660/6600/6650/1520ID, and IRB1200 robot families respectively.
Product Positioning: Sourced and verified by Konmask.com, these process wrist assemblies are targeted at maintenance engineers, system integrators, and procurement teams requiring reliable, specification-accurate replacements to minimize robot downtime in production environments.

Proven Application Environments
- Automotive Body-in-White (BIW): Spot welding and sealing on IRB6600/6650 lines requiring high-cycle wrist durability
- Arc Welding Cells: IRB2400 process wrist used in MIG/TIG welding with integrated cable management
- Material Handling & Palletizing: IRB660 heavy-payload applications with sustained axis 4–6 loading
- Electronics Assembly: IRB1200 compact wrist for precision pick-and-place in confined workspaces
- Painting & Dispensing: IRB1520ID integrated dress-pack wrist for paint and adhesive dispensing
- Food & Beverage: Washdown-rated configurations on IRB1200 for hygienic processing lines
Engineering Advantages
- OEM Dimensional Accuracy: Direct bolt-on replacement — no shimming, re-calibration offsets are minimal and within ABB’s standard mastering procedure
- Integrated Cable Routing: Process wrist design routes signal, power, and media cables internally, reducing external dress-pack wear
- High Repeatability Retention: Precision gear and bearing preload maintained to ABB factory specification (±0.03 mm for IRB2400; ±0.02 mm for IRB1200)
- Sealed Bearing Assemblies: IP67-rated seals prevent ingress of weld spatter, coolant, and particulate contamination
- Cross-Series Availability: Single sourcing point for three major ABB robot families reduces procurement complexity
System Architecture & Signal Flow
The process wrist assembly integrates with the robot’s axis 4–6 drive train. Mechanical torque is transmitted from the forearm gearbox through the wrist housing to the tool flange (ISO 9409-1 compliant). Internal conduits route:
- Motor resolver/encoder cables for axes 5 and 6
- Brake release wiring
- Customer process media (air, water, signal) via the integrated process channel
Compatibility with ABB IRC5 and OmniCore controller platforms is maintained through standard SMB (Serial Measurement Board) signal architecture. No firmware modification is required for OEM wrist replacement.

Technical FAQ
Q: Can 3HAC037835-001 be used on both IRB6600 and IRB6650?
A: Yes. The IRB6600 and IRB6650 share the same wrist interface. Confirm the payload variant (125/175/200 kg) does not affect wrist selection — all use the same process wrist assembly.
Q: Is mastering required after wrist replacement?
A: Yes. ABB recommends axis 4–6 mastering after any wrist replacement using the ABB mastering tool (3HAC16831-1) and RobotStudio or FlexPendant procedure.
Q: What is the difference between a process wrist and a standard wrist?
A: A process wrist includes an integrated internal conduit for routing process media (cables, hoses) through the wrist body, eliminating external dress-pack routing at the wrist joint. Standard wrists do not have this channel.
Q: Are refurbished units safe for production use?
A: Refurbished units supplied by Konmask are disassembled, inspected, re-sealed, and re-greased to ABB service manual specification. They are suitable for non-critical or backup applications. For high-cycle production lines, new OEM units are recommended.
Q: Do you supply the wrist gasket separately?
A: Yes. Wrist gasket kits are available separately. Contact support@konmask.com for the applicable gasket part number for your robot model.
