Head to head
Comau NJ-165 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 duty robot for handling and press tending
The world's most common heavy-duty spot-welding arm.

Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
On paper these two are close, both carry 165 kg and 3000 mm against 2655 mm of reach, near enough that the spec sheet alone will not decide it. They run different controllers, the Comau NJ-165 on the C5G 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. Mounting options differ: the Comau NJ-165 lists Floor and Ceiling, and the FANUC R-2000iC/165F lists Floor, Inverted, and Angle. Both are aimed at material handling and machine tending, with the Comau NJ-165 stretching to press tending and palletizing and the FANUC R-2000iC/165F to spot welding.
Choose this one when
Job fit first, then the controller and cell constraints that decide which arm you can actually install.
Choose the Comau NJ-165 when
- High payload for large part transfer
- Stiff arm holds accuracy under heavy load
- Proven in press tending and foundry lines
- Broad tooling compatibility
Watch for
- Large footprint and mass need dedicated foundation work
- Not suited to light or high speed tasks
Choose the FANUC R-2000iC/165F when
- Enormous installed base
- Wide reach and payload envelope
Watch for
- Large footprint
- Needs substantial safeguarding
Controller ecosystem
Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.
- Brand
- Comau
- Controller
- C5G
- Class
- 6-axis industrial
Service, spares, and pendant training for the Comau NJ-165 run through Comau's C5G stack.
- Brand
- FANUC
- Controller
- R-30iB Plus
- Class
- 6-axis industrial
Service, spares, and pendant training for the FANUC R-2000iC/165F run through FANUC's R-30iB Plus stack.
These arms run different controllers (C5G vs R-30iB Plus). If your team already programs one of them, retraining programmers and stocking a second set of spares usually costs more than a small payload or reach advantage on paper.
Mounting, footprint, and mass
How the arm can be oriented in the cell, and how much mass you have to mount.
| Field | Comau NJ-165 | FANUC R-2000iC/165F |
|---|---|---|
| Mounting | Floor and Ceiling | Floor, Inverted, and Angle |
| Robot mass | 1,240 kg | 1,090 kg |
| Protection (IP) | IP65 / IP67 | IP67 wrist & J3 / IP54 body |
Heavier arms want stiffer bases and more clearance around the swept volume, and they push freight and rigging costs up on the install. IP ratings only cover the section they name, so a wrist-only rating protects the wrist and nothing else; check the body rating separately before you commit the arm to a washdown or dusty cell.

Speed and cycle-time planning
Speed is rarely a single datasheet number across brands. Use payload, reach, and class as the planning frame, then confirm cycle time in a path study.
The Comau NJ-165 is a 6-axis industrial arm rated 165 kg at 3000 mm with ±0.09 mm repeatability. The FANUC R-2000iC/165F is a 6-axis industrial arm rated 165 kg at 2655 mm with ±0.05 mm. Class changes how speed shows up in a cell: collaborative arms slow down near people and can speed up in a guarded mode, while industrial arms run at rated speed inside a fence or scanner field. Which arm cycles faster on your part depends on the path, the payload, and the safeguarding, so confirm the takt with a path study before you quote it.
Common questions
- Which has more payload, the Comau NJ-165 or the FANUC R-2000iC/165F?
