Minnesota-based Tolomatic, a leading supplier of electric linear actuators, pneumatic actuators and power transmission products for factory automation, have released their new ServoWeld® actuators which have been redesigned for higher performance and to be lighter in weight.
The ServoWeld actuators are made especially for resistance spot welding applications in the automotive industry. The ServoWeld Advanced (SWA) actuator is based on a high level roller screw technology to deliver the maximum number of welds. The ServoWeld Base (SWB) actuator is built on an alternate roller screw design to provide longer life than typical ball screw and inverted roller screw technology, but at a more economical price than the SWA actuator.
The SWA and SWB ServoWeld models are available in two sizes: a smaller size 3 for lighter-duty weld schedules; and a size 4 for heavier-duty applications.
