ABB IRB 4600-20/2.50 vs FANUC M-710iC/20L
Two industrial arms a buyer shopping for material movement 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.
| ABB IRB 4600-20/2.50 | FANUC M-710iC/20L | |
|---|---|---|
| Class | Industrial arm | Industrial arm |
| Payload | 20 kg (44 lb) | 20 kg (44 lb) |
| Reach | 2510 mm | 3110 mm |
| Sold as collaborative | no | no |
| Applications listed | welding, machine tending, material movement, packaging | welding, material movement, sanding and finishing, pick and place |
| 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 20 kg and 20 kg. The gripper and the part decide it, not the arm: rated payload is measured at the wrist with no tool on it.
- The FANUC M-710iC/20L reaches 600 mm farther than the ABB IRB 4600-20/2.50. That matters for pallet height, bin depth and machine door clearance more than it matters at a bench.
- Neither is sold as collaborative. Both need guarding and an integrator's risk assessment before a person shares the floor with them.
- Both are listed for material movement, welding. The ABB IRB 4600-20/2.50 is also listed for machine tending, packaging. The FANUC M-710iC/20L is also listed for sanding and finishing, pick and place.
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.
From our matrix
ABB IRB 4600-20/2.50. ABB's spec table gives 2.51 m though the model name rounds to 2.50.
FANUC M-710iC/20L. Long arm L variant aimed at car body interiors and hard to reach areas.
