Head to head
FANUC M-710iC/50 vs FANUC M-710iC/70
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Mid-size workhorse for handling and welding lines
Higher-payload sibling for pallet and part transfer
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the FANUC M-710iC/70 carries more, 70 kg to the FANUC M-710iC/50's 50 kg. If precision drives the job, the FANUC M-710iC/50 holds the tighter repeatability at ±0.03 mm. Both run the R-30iB Plus controller, so programming, spare parts, and operator familiarity carry across either way. Both are aimed at material handling and machine tending, with the FANUC M-710iC/50 stretching to arc welding and assembly and the FANUC M-710iC/70 to palletizing.
Choose this one when
Job fit first, then the controller and cell constraints that decide which arm you can actually install.
Choose the FANUC M-710iC/50 when
- Wide work envelope for its class
- Slim wrist clears tight fixtures
- Shares spares with M-710iC family
- Proven uptime in high-volume lines
Watch for
- Payload ceiling limits it on heavier tooling
- Floor mount needs a reinforced pad at full speed
Choose the FANUC M-710iC/70 when
- Higher payload without a larger footprint
- Same envelope as the M-710iC/50
- Robust for continuous multi-shift duty
- Wide accessory and EOAT ecosystem
Watch for
- Heavier arm increases cycle inertia at full reach
- Larger power draw than the /50 variant
Controller ecosystem
Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.

Service, spares, and pendant training for the FANUC M-710iC/50 run through FANUC's R-30iB Plus stack.
- Brand
- FANUC
- Controller
- R-30iB Plus

- 6-axis industrial
Service, spares, and pendant training for the FANUC M-710iC/70 run through FANUC's R-30iB Plus stack.
Both arms run the R-30iB Plus controller, so pendant skills, program backups, and many spare parts carry over if you standardize on either model.
Mounting, footprint, and mass
How the arm can be oriented in the cell, and how much mass you have to mount.
| Field | FANUC M-710iC/50 | FANUC M-710iC/70 |
|---|---|---|
| Mounting | Floor, Ceiling, and Angle | Floor, Ceiling, and Angle |
| Robot mass | 560 kg | 560 kg |
| Protection (IP) | IP54 body (opt. IP67) / IP67 wrist & J3 | 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.
Application fit

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 FANUC M-710iC/50 is a 6-axis industrial arm rated 50 kg at 2050 mm with ±0.03 mm repeatability. The FANUC M-710iC/70 is a 6-axis industrial arm rated 70 kg at 2050 mm with ±0.04 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 FANUC M-710iC/50 or the FANUC M-710iC/70?
- The FANUC M-710iC/70 has more payload at 70 kg versus 50 kg.
- Which reaches farther?

- Which is more precise?
- The FANUC M-710iC/50 holds tighter repeatability at ±0.03 mm.
- Should I choose the FANUC M-710iC/50 or the FANUC M-710iC/70?
- Match the pick to the job. The FANUC M-710iC/50 is a 6-axis industrial arm at 50 kg and 2050 mm. The FANUC M-710iC/70 is a 6-axis industrial arm at 70 kg and 2050 mm.
- Do the FANUC M-710iC/50 and FANUC M-710iC/70 use the same controller?
- Yes. Both run the R-30iB Plus controller.
- How do the IP ratings compare?
- The FANUC M-710iC/50 is rated IP54 body (opt. IP67) / IP67 wrist & J3. The FANUC M-710iC/70 is rated IP67 wrist & J3 / IP54 body. Check wrist versus body coverage before washdown or dusty cells.
