# FANUC M-900iB/280

Hardware · `M-900iB/280` · verification: source checked

The FANUC M-900iB/280 is a six-axis industrial robot with a 280 kg payload and 2655 mm reach. It is a high-rigidity model based on the M-900iB/360, with a redesigned J3 arm for stiffness, intended for flow drill screwing, roller hemming, and other applications requiring accuracy under pressure. It is controlled by the R-30iB Plus controller series and offers ceiling, floor, angle, and wall mounting.
