FANUC R-2000iC/165F vs ABB IRB 6720: Large Robot Comparison
Updated: 9 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE This comparison includes family-level ranges: FANUC R-2000iC/165F lists 165 kg and 2655 mm, while ABB IRB 6720 lists 150–240 kg and 2500–3100 mm. Select an exact variant; maximum payload and maximum reach from different versions cannot be combined. |
→ CONSIDER FANUC R-2000iC/165F Consider it when its named configuration already meets the actual load and workspace requirements. This article compares 165 kg with a published reach of 2655 mm; include the gripper and part in the load. |
→ CONSIDER ABB IRB 6720 Consider it when an exact variant in this family meets the complete tool load and required workspace. This article compares 150–240 kg with a published reach of 2500–3100 mm; include the gripper and part in the load. |
💡 THE TAKEAWAY Choose exact order codes before comparing capacity or price. Confirm the selected variant’s payload and reach together, then validate the real tool, movement path and controls against the same acceptance test. |
The FANUC R-2000iC/165F and the ABB IRB 6720 both cover the 150–165 kg class used in automotive lines. The IRB 6720 runs from 150 to 240 kg, reaches up to 3100 mm and costs about 12% less. The R-2000iC/165F carries 165 kg over 2655 mm.
Quick verdict. The ABB IRB 6720 is the better value for new automotive and EV lines, with 150 to 240 kg versions, up to 3100 mm reach and a listed price $11,000 lower. The FANUC R-2000iC/165F is the better choice for FANUC lines and press-to-press handling.
