FANUC M-900iB/360 vs Yaskawa GP400: Heavy Robot Comparison
Updated: 10 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE Yaskawa Motoman GP400 has the higher stated load capacity and longer stated reach. Those figures help shortlist it for heavier loads or wider layouts, but do not prove a faster production cycle. |
→ CONSIDER FANUC M-900iB/360 Consider it when its stated load and reach already cover your task and its controls fit your equipment. This article compares 360 kg with a published reach of 2655 mm; include the gripper and part in the load. |
→ CONSIDER Yaskawa Motoman GP400 Consider it when additional load capacity and reach matter. This article compares 400 kg with a published reach of 2942 mm; include the gripper and part in the load. |
💡 THE TAKEAWAY Choose the robot that handles your actual tool and part through the required path, with controls and support your team can use. Compare complete installation quotes, rather than arm-only prices. |
The FANUC M-900iB/360 and the Yaskawa Motoman GP400 are heavy-payload robots with ±0.1 mm repeatability. The GP400 carries 40 kg more, reaches about 290 mm further and is listed 25% lower. The M-900iB/360 weighs 1300 kg less.
