Curtiss-Wright Sensors & Controls Division (Gilbert, AZ) has released its next-generation Exlar brand FTX Series actuators. The high-force electric rod style actuators feature:

  • A design based on planetary roller screw technology.
  • A compact form factor.
  • A suitable alternative to hydraulic cylinders. 
  • A continuous force rating to 178 kN (40,000 lbf).
  • Speed to 875 mm/sec (34 in/sec).
  • Stroke lengths from 150 mm (6 inches) to 900 mm (3 feet).

The FTX215, a next-generation version of the current FT80 model, features: 

  • A capacity planetary roller screw that offers up to 15x the life and higher shock load resistance.
  • IP65 (min) environmental protection.
  • Idler pulley design that simplifies motor installation and belt tensioning/maintenance.
  • Grease zerk fitting and removable front seal bushing for maintenance and re-greasing of nut assembly to maximize actuator life.
  • Modular design with bolt-on mounting hardware allows mounting style reconfiguration in the field using available tools.
