Head to head
ABB IRB 6640 vs FANUC R-2000iC/165F
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Heavy-payload foundry-proven material handler
The world's most common heavy-duty spot-welding arm.
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the ABB IRB 6640 carries more, 235 kg to the FANUC R-2000iC/165F's 165 kg. They run different controllers, the ABB IRB 6640 on the IRC5 and the FANUC R-2000iC/165F on the R-30iB Plus, so whichever platform your team already programs and stocks parts for is a real tiebreaker. For a tight or overhead cell, the FANUC R-2000iC/165F lists Inverted and Angle mounting, which the other does not. Both are aimed at material handling and machine tending, with the ABB IRB 6640 stretching to palletizing and the FANUC R-2000iC/165F to spot welding.
- Proven in foundry and press-tending duty
- High payload with foundry-sealed options
- Rigid structure holds accuracy under load
- Long service life in continuous operation
- Enormous installed base
- Wide reach and payload envelope
