Product Details And Specifications

ABB 3HAC030868-001 Balancing Device – Obsolete IRB6640 / IRB6620 Spare Part

The ABB 3HAC030868-001 (cross-referenced as 3HAC026268-001 and 3HAC024504-001) balancing device is no longer manufactured by ABB. DriveKNMS maintains RFQ-reviewed sourcing status of this component, sourced through controlled industrial channels. This is not a catalog listing — inventory is finite and allocated on a first-confirmed basis.

RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Solving the Discontinued Hardware Crisis

The ABB IRB6640 and IRB6620 series were deployed extensively from the mid-2000s through the 2010s across automotive body-in-white, press tending, and palletizing applications. Thousands of these manipulators remain in active production service globally. ABB's end-of-life policy for this generation means that OEM spare parts — including the 3HAC030868-001 balancing device — are no longer available through standard distribution channels.

The balancing device is a load-bearing mechanical component that counteracts gravitational torque on Axis 2. Without a functioning unit, the robot cannot maintain positional accuracy under load, servo motor current draw increases abnormally, and the IRC5 controller will generate fault codes that halt the cell. There is no software workaround. There is no recalibration that compensates for a failed balancing device. The only path to restoring production is physical part replacement.

Condition & Reliability Assurance

DriveKNMS applies a structured 5-step inspection protocol to all discontinued mechanical and electromechanical components before dispatch review:

Key Features for System Maintenance

How do I know the unit is genuine ABB and not a counterfeit?
We source exclusively from decommissioned OEM-installed equipment and authorized industrial surplus channels. Part markings, casting references, and dimensional characteristics are cross-checked against known-good units. If you require additional verification documentation, discuss this with our team before order confirmation.
