FANUC CRX-3iA vs Kawasaki duAro2
Two collaborative arms a buyer shopping for assembly and screwdriving would honestly weigh against each other, with the manufacturer-published figures in one table and a plain reading of what the differences mean on a floor. We sell across brands, so we have no reason to tilt it.
| FANUC CRX-3iA | Kawasaki duAro2 | |
|---|---|---|
| Class | Collaborative arm | Collaborative arm |
| Payload | 3 kg (7 lb) | 3 kg (7 lb) |
| Reach | 692 mm | 785 mm |
| Sold as collaborative | yes | yes |
| Applications listed | welding, assembly and screwdriving, inspection | assembly and screwdriving, machine tending, pick and place, material movement |
| Specs checked | 2026-08-22 | 2026-08-22 |
Every figure is a manufacturer-published claim, checked on the date shown against the maker's own material, and not one of them survives contact with your part, your rate and your floor without an applications review. Prices are deliberately absent: quotes are prepared by our team and confirmed with the manufacturer.
What the numbers mean on the floor
- Payload is effectively a tie at 3 kg and 3 kg. The gripper and the part decide it, not the arm: rated payload is measured at the wrist with no tool on it.
- The Kawasaki duAro2 reaches 93 mm farther than the FANUC CRX-3iA. That matters for pallet height, bin depth and machine door clearance more than it matters at a bench.
- Both are sold as collaborative. That describes a feature set, not a safety verdict: the risk assessment on your part, your gripper and your speed is what decides whether anyone works beside it. Collaborative does not mean fenceless.
- Both are listed for assembly and screwdriving. The FANUC CRX-3iA is also listed for welding, inspection. The Kawasaki duAro2 is also listed for machine tending, pick and place, material movement.
What a spec sheet cannot tell you
The gripper, the fixture and the integrator decide more of the outcome than the arm. Cycle time on your part is a test, not a datasheet figure. Service footprint, spare parts and who answers the phone at 2 AM differ by brand and by state. And the price difference between two arms in the same class is usually smaller than the difference between two integrators' quotes for the same cell. A model number is not a specification, and the gripper is the project.
