Unreliable Screw-Type Electro-Mechanical Actuators (EMAs)

  • EMAs fail from shock loads and concentrated loading.
  • EMAs require regular lubrication and maintenance to avoid premature failure.
  • EMAs are very expensive at forces over 5,000 lbs.
  • EMAs require a brake to hold position, otherwise can be back-driven and have backlash.
  • Have limited stroke length (24”) without incurring expensive premiums.

Issues with Screw-type Electro-Mechanical Actuators

Old Hydraulic Cylinder Technology

  • Inevitably, leaks create downtime and safety issues.
  • They are energy inefficient.
  • Require costly fluid replacement and disposal of used fluid.
  • They are difficult and expensive to precisely control.
  • Require excessive maintenance by a dwindling cohort of trained maintenance personnel.
