Head to head
FANUC M-410iB/140H vs FANUC M-410iC/185
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
High-speed four-axis palletizer for case handling
Heavy-duty palletizer for bagged and boxed goods
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the FANUC M-410iC/185 carries more, 185 kg to the FANUC M-410iB/140H's 140 kg. Both run the R-30iB Plus controller, so programming, spare parts, and operator familiarity carry across either way.
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-410iB/140H when
- High cycle rate for case palletizing
- Low-profile base simplifies mezzanine layouts
- Simple four-axis kinematics ease maintenance
- Strong reach for multi-pallet cells
Watch for
- Limited to palletizing-style motion, not general handling
- Requires guarding for high-speed swing radius
Choose the FANUC M-410iC/185 when
- Long reach covers multiple pallet positions
- High payload handles bagged and bulk loads
- Consistent stacking accuracy at speed
- Compatible with FANUC palletizing software tools
Watch for
- Large swing radius needs generous cell footprint
- Overkill for light carton palletizing
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-410iC/185 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-410iB/140H | FANUC M-410iC/185 |
|---|---|---|
| Mounting | Floor | Floor |
| Robot mass | 1,200 kg | 1,600 kg |
| Protection (IP) | IP54 | IP54 |
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
Where each arm is aimed, based on the applications listed on its robot page.
Both pages list palletizing, packaging, and material handling.

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-410iB/140H is a palletizing arm rated 140 kg at 2850 mm with ±0.05 mm repeatability. The FANUC M-410iC/185 is a palletizing arm rated 185 kg at 3143 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
