ABB IRB6700 Series: Comprehensive Module Range and Technical Overview

The ABB IRB6700 is a heavy-duty industrial articulated robot platform deployed across global heavy industries including petrochemical plants, nuclear facility maintenance operations, automotive body-in-white assembly lines, and offshore refinery environments. With payload capacities ranging from 150 kg to 300 kg and reach variants spanning 2.6 m to 3.2 m, the IRB6700 family represents ABB Robotics' flagship sixth-axis articulated robot generation, succeeding the IRB6640 and IRB6650 lineages. Its modular mechanical and electrical architecture — built around the IRC5 controller ecosystem — makes it a long-term capital asset in facilities requiring high-cycle, high-payload automation with minimal downtime tolerance.

The Evolution of IRB6700 Architecture

The IRB6700 was introduced by ABB in 2013 as a direct successor to the IRB6640 series, incorporating a redesigned lean-ID (Integrated Dressing) cable management system and a new generation of servo drive modules compatible with the IRC5 Single Cabinet and IRC5 Compact controllers. The mechanical architecture uses a cast iron and high-tensile steel frame with a 6-axis configuration (J1–J6), each axis driven by dedicated AC servo motors paired with harmonic drive or planetary gearboxes depending on the axis load profile.

Early IRB6700 units (2013–2016) used first-generation balancing cylinder assemblies (3HAC045063-001) and axis computer boards that required manual calibration via the FlexPendant. From 2017 onward, ABB introduced updated wrist assemblies and revised harness routing kits (3HAC055433-001, 3HAC055435-001) to reduce cable fatigue in high-cycle applications. The 200/150 variant designation refers to the 200 kg payload at 2.6 m reach and 150 kg payload at 3.2 m reach configurations — the most widely deployed variant globally.

As of 2024, the IRB6700 remains in active production, though several sub-component assemblies from the 2013–2018 build period are transitioning to end-of-life status. Facilities operating pre-2018 units must source legacy spare parts through specialist distributors, as ABB's direct spare parts availability for early-generation harness and balancing assemblies is increasingly constrained.

Sourcing Hard-to-Find & Obsolete IRB6700 Parts

DriveKNMS maintains a dedicated inventory program for ABB IRB6700 components that have entered end-of-availability status through ABB's direct supply chain. This includes first-generation balancing cylinder assemblies (3HAC045063-001, 3HAC045067-001), early-specification cable harness kits, and pre-2017 wrist unit assemblies.

Our sourcing methodology for lifecycle-extended IRB6700 parts includes: direct procurement from decommissioned robot lines in automotive and petrochemical facilities; cross-referencing ABB's supersession tables to identify approved replacement part numbers; and maintaining buffer stock of high-failure-rate consumables such as cable harnesses and balancing cylinder seals. For facilities operating IRB6700 units beyond their original 10-year design lifecycle, DriveKNMS provides a long-term maintenance supply agreement covering critical spare parts with guaranteed lead times.

All sourced parts are accompanied by full traceability documentation including original manufacturer lot codes where available, inspection records, and functional test certificates.

Quality Control for the IRB6700 Range

IRB6700 mechanical and electromechanical components undergo a structured inspection protocol at DriveKNMS prior to dispatch:

Balancing Cylinder Assemblies (3HAC045063-001 / 3HAC045067-001): Gas pressure verification against ABB specification (nominal 60–80 bar depending on variant); visual inspection of piston rod surface for scoring or corrosion; seal integrity test under static load simulation.

Cable Harness Kits (3HAC055433-001 / 3HAC055435-001): Continuity testing across all signal and power conductors; insulation resistance measurement (minimum 100 MΩ at 500 VDC); connector pin inspection for fretting corrosion and mechanical retention force.

Servo Motors: Winding resistance measurement per phase; insulation resistance test; encoder signal verification via bench test rig; bearing noise assessment under no-load rotation.

Gearboxes: Backlash measurement against ABB tolerance specification; oil seal integrity check; input/output shaft runout measurement.

All test results are recorded in a component-level inspection report issued with each shipment.
