I was wondering, if there is a shock load resistant electromechanical actuator that can withstand powerful impacts? Is there an electromechanical counterpart for pneumatic cylinders that is as shockresistant as hydraulic or pneumatic actuators?

And if not, is there some kind of way to make them withstand impacts via external parts?

  • $\begingroup$ You need to quantify what you mean by shock, how many G's ??? Actuators based on the solenoid principal can be made very rugged because they are basically simple: a coil and a moving armature . You could take a standard actuator and "beef it up" if you need to. $\endgroup$ – William Hird Oct 19 '18 at 20:47
  • $\begingroup$ I would say about 1000N. The actuator that I need should be fast (25-50 in/s), powerful (1,500+ lbf), shock-resistant and preferably electromechanical. Aren't solenoid actuators too weak for this? $\endgroup$ – testdummy Oct 19 '18 at 21:01

EDrive Corporation makes a linear actuator called the Eliminator SS rated at 65in/sec and a thrust of 4000lbf. If you want to increase its shock resistance you can take the actuator and mount it in a ruggedized housing of some sort with an opening for actuator arm to do its work. You can call the company and find out if it has a shock rating.
