Heavy-Payload Robotic Arm Joint Solution — ABB IRB6700 / IRB760 | Axis Reducer Series
Where This Product Is Used
The ABB IRB6700 and IRB760 Axis Reducer is a precision gearbox assembly engineered for the joint axes of ABB’s heavy-payload industrial robot arms. These reducers are deployed across the most demanding automation environments globally:
- Automotive Body-in-White (BIW) Welding Lines — Spot welding and MIG/MAG welding cells requiring high repeatability and torque stability at axes 1–6.
- Press Tending & Stamping Automation — High-cycle press-to-press transfer with IRB6700 robots handling payloads up to 235 kg.
- Foundry & Die Casting — Harsh thermal and particulate environments where gearbox integrity is critical for uptime.
- Palletizing & Material Handling — End-of-line palletizing with IRB760 robots requiring smooth, low-backlash axis motion.
- Machine Tending — CNC machine loading/unloading with precise positional repeatability (±0.05 mm).
- Structural Assembly — Aerospace and heavy equipment assembly lines where torque consistency is non-negotiable.

Why Engineers Specify This Model
- OEM Dimensional Accuracy: Direct drop-in replacement — no shimming, re-calibration offsets, or adapter plates required.
- Torque Density: High reduction ratios (up to 245:1) deliver maximum output torque in a compact envelope, critical for axes 1 and 2 of the IRB6700.
- Low Backlash: Maintains ±0.05 mm TCP repeatability over the robot’s rated service life.
- Thermal Stability: Designed for continuous-duty cycles in foundry and press environments (ambient up to 52°C).
- Sealed Construction: Integrated sealing prevents lubricant contamination in wash-down and dusty environments.
- Multi-Ratio Availability: Four ratio variants (200/150/245/30) cover all primary axes of the IRB6700 and IRB760 platform in a single sourcing event.

Application-Specific FAQ
Q: Are these reducers compatible with both IRB6700 and IRB760?
A: Yes. The four part numbers in this listing cover axis positions across both the IRB6700 (all payload variants: 150/200/235/300 kg) and the IRB760 platform. Always verify the ratio against your robot’s axis configuration in the ABB product manual.
Q: What is the expected service life of an ABB axis reducer?
A: Under normal operating conditions and with correct lubrication intervals (per ABB maintenance schedule), axis reducers typically achieve 20,000–40,000 operating hours before replacement is recommended.
Q: Can I replace the reducer without full robot recalibration?
A: OEM replacement reducers maintain the same mechanical zero reference, but ABB recommends performing axis calibration (using the ABB CalibWare tool or Levelmeter) after any gearbox replacement to ensure TCP accuracy.
Q: Do you supply the lubricant required for reinstallation?
A: We can supply ABB-specified gearbox grease alongside this part. Please request this when submitting your RFQ.
Q: What is your minimum order quantity (MOQ)?
A: MOQ is 1 unit. Bulk pricing is available for orders of 5+ units. Contact us for a volume quotation.
Q: Do you offer a warranty?
A: Yes. All OEM parts carry a 12-month warranty against manufacturing defects from the date of shipment, subject to correct installation and operating conditions.
