The Nachi MZ50F is a six-axis articulated industrial robot with a hollow wrist for internal cable routing. It is intended for machine tending, material handling, palletizing, and dispensing, and is rated IP67 equivalent for harsh environments. Its position repeatability is ±0.06 mm, with a stated payload of 50 kg and reach of 2102 mm.
The general specifications table lists four model columns: M235F-01, M250F-01, M270F-01, and M250LF-01; payload, reach, speed, and weight values vary by model.
The robot uses AC servo motors.
The hollow wrist allows wiring to be routed internally.
Air tubes are φ10 x 2; application cables are 24 wires.
Clean rating is equivalent to ISO Class 4 based on ISO 14644-1.
Noise level is 80 dB, measured as A-weighted equivalent sound level under JIS Z 8737-1 (ISO 11201) at maximum payload and maximum velocity.
The general specifications table lists robot weight as 593 kg and 611 kg; additional information lists 608 kg.
The general specifications table lists maximum reach as 2102 mm and 2502 mm; additional information lists 2102 mm.
The general specifications table lists maximum payload as 35 kg, 50 kg, 70 kg, and 50 kg across the model columns; additional information lists 50 kg.
The general specifications table lists installation as floor or inverted; additional information lists angle, cleanroom, floor, tabletop, and invert/ceiling mounting.
Maximum static load torque is listed as J4/J5 165, 216, or 309 N·m and J6 102, 147, or 170 N·m depending on model.
Maximum moment of inertia is listed as J4/J5 16 or 30 kg·m² and J6 5 or 12 kg·m² depending on model.
Safety
Ambient humidity must be 20 to 85%RH with no dew or frost.
Vibration must not exceed 0.5G (4.9 m/s²).
Use is limited to 1000 m or lower sea level; ambient temperature has limitations above the allowable altitude.
An explosion-proof version is not available.
Fluids that deteriorate sealants, such as gasoline-based cutting fluids, chlorine, alkali, acids, and organic solvents, cannot be used.
The robot is IP67 equivalent, the wire-harness portion is IP65 equivalent, and the robot controller is IP20 equivalent.
Motion range is limited for wall mount and tilted mount; example axis 1 motion range is ±30° for wall mount.
The robot packaging is not dust proof; clean the robot by wiping or removing dust and fine particles before bringing it into a cleanroom.
Noise level is 80 dB.
