Hollow wrist, High-speed and high-precision
35/50/70Kg medium payload robot

Nachi's first hollow wrist in the middle payload class
Supports a wide range of applications withworld-class high-speed andhigh-precision

Lightweight, slim and ridged bodysupports a wide range ofapplications■ Smallest turning interference radius
and installation area in its class■ Space-saving with a lightweight andslim body
■ Anti-corrosion treatment andanti-coolant coating are standard
equipment(protection class IP67)

High speed and High precision■ High-speed, high-precision motion
improves productivity

Smart cable routing■ Interference is avoided by wiring routing
through the hollow wrist
