Engineering Advantages
- Zero-compromise OEM fit: Identical mounting dimensions, shaft interface, and bolt pattern to factory specification — no shimming or adaptation required.
- Ultra-low backlash: ≤ 1 arc-min ensures positioning repeatability critical for path-accuracy applications.
- High torsional stiffness: RV cycloidal architecture distributes load across multiple contact points, resisting shock and overload.
- Extended service life: Hardened alloy steel cycloid discs and precision needle bearings rated for millions of cycles.
- Sealed lubrication: Factory-filled grease eliminates field lubrication errors during installation.
System Architecture & Signal Flow
In a typical ABB robot joint, the servo motor output shaft drives the RV reducer input (high-speed stage). The cycloidal disc set (low-speed stage) converts high-speed / low-torque rotation into low-speed / high-torque output at the joint flange. The 3HAC022279-001 occupies this drivetrain position, with the 224:1 ratio providing the mechanical advantage required for precise, repeatable joint positioning under full payload.
Signal path: Servo Drive → Motor Shaft → RV Input Pinion → Cycloidal Stage (224:1) → Output Flange → Robot Link

Technical FAQ
Q: Is 3HAC022279-001 interchangeable with 76003HAC056861-001 or 76003HAC14726-2?
A: Yes. These are ABB’s alternate/superseded part numbers for the same RV 400C-224-26-76 reducer assembly. All three P/Ns reference the identical unit.
Q: What robot models use this reducer?
A: This unit is used in specific joint axes of ABB IRB series robots. Please provide your robot model and axis number for a definitive compatibility confirmation.
Q: Can I replace this reducer in the field without ABB service?
A: Reducer replacement requires mechanical disassembly of the robot joint and precise torque procedures per ABB service manual. Konmask recommends qualified ABB-certified technicians perform the replacement.
Q: What is the lead time?
A: Standard in-stock units ship within 3–5 business days. Contact us for urgent requirements.
Q: Do you provide a warranty?
A: Yes. Genuine OEM units carry the standard ABB warranty. Konmask additionally provides a 90-day quality guarantee on all shipped units.
