ABB IRB 6700-150/3.20 vs KUKA KR 150 R3100-2
Two industrial arms a buyer shopping for machine tending 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 6700-150/3.20 | KUKA KR 150 R3100-2 | |
|---|---|---|
| Class | Industrial arm | Industrial arm |
| Payload | 150 kg (331 lb) | 150 kg (331 lb) |
| Reach | 3200 mm | 3100 mm |
| Sold as collaborative | no | no |
| Applications listed | material movement, palletizing, machine tending, welding | machine tending, material movement, press brake tending |
| 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 150 kg and 150 kg. The gripper and the part decide it, not the arm: rated payload is measured at the wrist with no tool on it.
- Reach is close, 3200 mm against 3100 mm. Neither will rescue a layout that puts the pick and the place too far apart.
- 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 machine tending, material movement. The ABB IRB 6700-150/3.20 is also listed for palletizing, welding. The KUKA KR 150 R3100-2 is also listed for press brake tending.
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.
