ABB 3HAC043073-001 Reduction Gear – IRB 6700 Series Spare Part

Technical Specifications

Note: Electrical and torque parameters vary by axis configuration. Confirmed specifications are provided upon request with axis and serial number details. No parameters are stated here that cannot be verified.

Solving the Critical Spare Hardware Problem

The ABB IRB 6700 is one of the most widely deployed heavy-payload industrial robots in automotive, foundry, and general manufacturing environments. Facilities that installed IRB 6700 units between 2013 and 2018 are now entering the phase where mechanical wear on reduction gears becomes a statistically predictable maintenance event. The reduction gear at each joint axis absorbs continuous cyclic load. Fatigue, lubricant degradation, and micro-fracture accumulation are not failures that announce themselves in advance — they manifest as positioning drift, then as hard faults, then as complete axis lock.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Condition and Reliability Assurance

Every 3HAC043073-001 unit processed by DriveKNMS passes a five-stage inspection protocol before it is offered for sale:

• Stage 1 – Visual and Mechanical Inspection: Housing integrity check, input/output shaft examination, seal condition assessment. Units with housing cracks, corrosion penetration, or deformed mounting surfaces are rejected at this stage.
• Stage 2 – Backlash and Rotational Resistance Measurement: Gear backlash is measured against OEM tolerance specifications. Excessive backlash indicates internal wear that will accelerate under load.
• Stage 3 – Lubrication Assessment: Internal lubricant condition is evaluated. Contaminated or degraded lubricant is replaced with the correct OEM-specified grease type and quantity.
• Stage 4 – Corrosion and Pin Inspection: All mounting pins, dowel holes, and connector interfaces are inspected for corrosion, thread damage, and dimensional conformance.
• Stage 5 – Documentation Review: Where available, manufacturing batch records and prior service history are reviewed. Units with unresolved service history gaps are flagged and disclosed to the buyer.

Units that pass all five stages are classified as verified serviceable. Units that pass stages 1–3 with minor cosmetic findings are classified as verified serviceable with noted condition. No unit is shipped without a written condition report.

Key Features for System Maintenance

• Drop-in replacement: The 3HAC043073-001 is a direct mechanical replacement for the original factory-installed unit. No axis reconfiguration is required.
• No reprogramming required: Reduction gear replacement on the IRB 6700 does not require robot program modification. Post-installation calibration follows the standard ABB axis calibration procedure.
• Avoids engineering reconstruction costs: Replacing a reduction gear preserves the existing robot controller, wiring harness, end-of-arm tooling, and all associated fixturing. The alternative — robot replacement — requires re-qualification of every downstream process parameter.
• Compatible with existing ABB IRC5 and OmniCore controllers: No controller-side changes are required for a like-for-like reduction gear replacement.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.
