LGA – Captive linear actuators

In the case of linear actuators with linear guide (captive), the plastic threaded nut is injection-molded into the hollow shaft rotor of the stepper motor and positively connected to it. If the motor is energized, the connection of lead screw and threaded nut transforms the rotary movement of the rotor into the linear movement of the lead screw. For this purpose, a linear guide is attached to the front of the lead screw and prevents the lead screw from rotating. 

  • Compact linear guide
  • Two motor lengths 
  • Various windings 
  • Different stroke lengths and lead screw versions 
  • Can optionally be configured with encoder
  • Integrated connector
