Nachi SRA Series Handling Robots
Manufacturer: NACHI
Model: SRA Series: SRA100/166/210/166L/120EL
Features
World Class Speed Robot
Robot motion makes minimum cycle times unbeatable. Light weight and high rigidity design makes high acceleration and minimum vibration. Maximum speed on all axes reduces cycle time. Improved productivity by these design.
Easy to use
Improved motor drive controls for accurate positioning and repeatability.
Slim and compact design allows closer installation in less floor space.
Improved maintenance item. It can do easy parts replacement and inspection.
Energy saving
Power consumption reduced 15% from existing model by reducing the robot’s weight by 20% and using newest motor drive controls.
Operating range
The specifications are subject to changes without notice.
In case that an end user uses this product for military purposes or production of weapons, this product may be liable for export restrictions stipulated in the Foreign Exchange and Foreign Trade Law. Please go through careful investigation and necessary formalities for export.
