Tolomatic's SWA and SWB models are available in a smaller size 3 for lighter-duty weld schedules and a size 4 for heavier-duty applications.
Tolomatic introduces the new ServoWeld actuators, redesigned for higher performance and are lighter weight compared to other screw technologies. Featuring roller screws, the ServoWeld actuators are made especially for resistance spot welding (RSW) applications in the automotive industry. 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. Both sizes are available in a variety of roller screw thread pitches (5mm and 10mm), motor voltages (230Vac & 460Vac) and multiple options for rod ends, feedback & connectors, and water cooling. These models can produce actuator forces at the rod up to 4,000 lbf/17.8 kN, lasting 20+ million welds and holding +- 3% force repeatability over the life of the actuator. Each model comes equipped as standard with a re-lubrication port to easily service the actuator without disassembly from the weld gun to maximize its life.
