IMA Linear Servo Actuators

The IMA linear servo actuator includes an integrated servo motor to simplify mechanical designs 

The IMA integrated motor actuator features a unique integrated servo motor design in a compact, industrial package, that removes the need to source and attach a separate servo motor to the system.  Ideal for hydraulic replacement, tight spaces, or when the actuator is exposed to a high level of shock and vibration.  

  • 4 body sizes with built-to-order stroke lengths and mounting options 
  • Stroke lengths up to 18 inches (1,524 mm) 
  • Forces up to 8,000 lbf (35.8 klN) 
  • Ball and Roller Screw options 
  • IP67 option to protect against dust and water ingress
