Exterior dimensions and working envelope
MC350/MC280/MC470P
by Nachi
Linkage-less construction is simple and compact
- Simple construction has no counterweights or parallel linkage.
- Compact form can be installed in small places.
Expansive operating stroke and lifting capabilities
- Plenty of wrist torque (1.7 times our existing model) easily handles large work pieces.
- Long arm type (MC280L) has maximum reach of 3,101 mm
- Super heavy lifting type (MC470P) can lift up to 470 kg (wrist must be directed downward)
High-speed motion
- Lower weight and greater rigidity make it the fastest robot in its class.
- Reduce cycle times by up to 15% (compared to our existing model).

(*1) Load speci cation of number 1 arm varies according to wrist load conditions and installation position.
(*2) Note that the allowable moment of inertia of wrist varies with the wrist load conditions.
(*3) JIS B 8432 compliant.
(*4) Permitted height is not higher than 1,000m above sea level. If used in higher place, permitted temperature is affected by height.
(*5) Software limits the downward vertical range of axis 5 to ±5°.
Axis 4 can move ±360° and axis 5 can move ±125° only when the encoder correction screen or the software limit settings screen is open.
Axis 4 can move ±360° and axis 5 can move ±125° only when the encoder correction screen or the software limit settings screen is open.
