The SIASUN SR360A-280/3.20 robot integrates the advantages of high rigidity, high speed, easy maintenance, and easy deployment. The J5 axis adopts a backlash-free gearbox to enhance overall rigidity and reduce start-stop vibration. It is equipped with self-developed high-torque motors, increasing spot welding rhythm by over 10%. The robot body features a no-counterweight design to lower the failure rate. The control cabinet supports mainstream protocols and reserves expansion space, facilitating system integration and production line deployment.
