Nachi SRA166/210-01A Spot Welding Robots
Manufacturer: NACHI
Model: SRA166/210-01A
Features
World Class Speed Robot
Robot motion makes minimum cycle times unbeatable. Light weight and high rigidity design results in high acceleration and minimum vibration. Maximum speed on all axes reduces move time. All this provides dramatically improved productivity.
Superior Spot Welding Capability
Industry leading advanced servo gun software features and technologies.
SRA robot ease of use improves the bottom line
Improved drives and motors for accurate positioning and better repeatability.
Compact design allows closer installation in less floor space.
Improved energy efficiency
Power consumption reduced 15% from existing models by reducing the robot’s weight by 20% and using cutting edge motor drive controls.
Controller
FD11
Operating range
This screw supports up to 210 kg (P.C.D.160).
Use this screw for loads up to 166 kg (P.C.D.125).
Suitable for loads up to 100 kg (P.C.D.92).
