ServoWeld® Resistance Spot Welding Actuators
ServoWeld GSWA Series servo actuators are used in servo resistance spot welding for robotic applications. They combine servo motor technology in a powerful high-force actuator for a compact profile and faster resistant spot weld cycles—perfect for automotive body-in-white spot welding applications.
Product Lineup
CSWX Compact ServoWeld Integrated Servo Spot Welding Actuators
ServoWeld® CSWX integrated servo spot welding actuator offers high performance in a compact package
The Compact ServoWeld® Actuator (CSWX) is the latest generation of ServoWeld actuators offering high force capability in a smaller package. Its modular design allows the CSWX to more easily adapt to project variability and supports our global manufacturing strategy. Tolomatic’s ServoWeld family of lighter weight integrated servo motor actuators for resistance spot welding (RSW) provide a cost-effective actuator design and best-in-class performance.
CSWX integrated servo motor actuators offer:
- 30+ million welds in typical welding applications with proper maintenance
- Standard roller screw with highest dynamic load rating for more welds over competing roller screws, ball screws or pneumatic actuators
- Skewed motor windings designed for welding minimizes motor cogging for the best force repeatability
- Compact actuator design
- Forces to 4,047 lbf (18 kN)
- Optional Features
- Water cooling
- Force feedback

GSWA33 ServoWeld Guided Resistance Spot Welding Servo Actuators
ServoWeld® GSWA33 Series spot welding actuators provide lighter weight and an optional enclosed anti-rotate assembly.
The ServoWeld GSWA33 series actuator provide peak thrusts of 2,100 lbf (9.3 kN) at a lighter weight enabling faster robot moves and faster weld schedules. The GSWA33 can be used on a variety of resistance spot welding gun applications (pinch guns, X guns, C guns) including weld guns which require the actuator to have anti-rotate of the thrust rod. Utilizing a standard roller screw, the GSWA33 provides the longest life (most welds) of any spot welding actuator on the market in its size, weight and force class. GSWA33 spot welding servo actuators are highly efficient and its broad performance range allows it to easily handle multiple weld schedules and accommodate different materials/material thicknesses in resistance spot welding.
GSWA33 resistance spot welding actuators offer:
- 20+ million cycles with minimal maintenance
- Standard roller screw with highest dynamic load rating for more welds over competing roller screw, ball screws or pneumatic actuators
- ±3% force repeatability over life of actuator
- Light-weight actuator design
- Forces to 2,100 lbf (9.3 kN)
- Optional water cooling
- Optional internal guide for anti-rotate of the thrust rod
- Integration for 7th axis operation with most global robot manufacturers
