The Nachi SRA100H and SRA133HL robots redefine spot welding with their innovative internal cable management system and unparalleled speed, making them the ultimate choice for high-performance operations.

Smart Cable Management

  • Spot welding cables and utility lines are routed through the hollow forearm and wrist for protection, ensuring long life. No surprises from swinging dress cables not modeled in simulation. Minimize interferences, much better than external dress solutions.

World’s Fastest Robot

  • The best motion control in the class makes cycle times unbeatable. Light weight, highly rigid design robot for high acceleration with minimum vibration. The high speed of all axes provide minimized movement times. Dramatically improves manufacturing productivity.

Controller

  • FD11
  • Simplified Programming: Internal cable routing facilitates accurate offline programming and simulation, streamlining your workflow.
