integrated servomotor | actuator for weld-guns

GTW Series servomotor | actuators integrate with weld-gun robotic systems, Pinch, C-Gun, or X-Gun! These actuators have built-in mounting features for adaption to a variety of weld-gun configurations as well as robotic interfaces enabling quick and easy hookup. Offering 15x longer life than the ordinary ball screw and 3x the power density means the GTW Series actuators will last for over 20 million welds under typical weld profiles.

 

BENEFITS

  • Programmability and precision of electric actuators
  • Power density, durability, and form factor of hydraulic actuators
  • Seamless integration with KUKA (KRC4 & KRC5), ABB, Comau, and Fanuc robot controllers as well as Bosch Rexroth and Festo 7th axis drive controllers
  • Environmentally sealed for use in harsh industrial environments
  • Built-in mounting features for adaption to a variety of weld-gun configurations
