SWA/SWB ServoWeld® electric cylinder actuators

Tolomatic’s ServoWeld SWA and SWB are integrated servo electric cylinder actuators for resistance spot welding. They use roller screw technology for high dynamic load ratings and longer life than ball screws or pneumatics. The actuators provide force repeatability of ±3% over their lifetime. With options like water cooling and lightweight design they suit high-demand robotic and welding processes. The SWA series delivers peak force up to 24 kN and the SWB series up to 22.0 kN. Both models support push-pull forces and are compatible with robot brands such as ABB Fanuc and Kuka.
