Spot welding auto chassis – Tolomatic

Manufacturer: Tolomatic
Product used: GSWA ServoWeld® Actuator

Application description:

Resistance spot welding (RSW) chassis – 4448 to 13,445 N and 10,000,000 welds


An automotive plant was using a servo actuator with a reverse parallel style motor mount on their RSW chassis to perform spot welding. The actuator/chassis combination resulted in a large footprint and heavy overall weight. The customer wanted a lighter weight and smaller actuator/chassis combination.


Tolomatic provided a GSWA44 ServoWeld® Actuator with an integrated servo motor, saving space with its smaller footprint and its lighter weight. The actuator also eliminated the need for belt and gear torque transmission.

Customer benefit:

  • Smaller, lighter weight actuator/chassis combination;
  • No maintenance of belts or gears;
  • Increased production from reduced downtime;
  • Faster cycle times from improved RSW chassis performance;
