Electric rod style linear actuator.

Curtiss-Wright Corporation has expanded its Exlar FT Series™ universal electric rod style linear actuator product line with the release of the FT45 model.

The FT Series roller screw driven actuators offer high thrust, high speed, and high robustness in a compact form factor, making them an ideal alternative to hydraulic cylinders. With continuous force rating to 40,000 lbf (178 kN), speed to 60 in/sec (1,500mm/sec) and stroke lengths from 6 inches (150mm) to 8 feet (2,400mm) the FT Series can be applied across a wide range of linear motion applications.

The new FT45 has a continuous force rating of 10,000 lbf (44.5 kN), filling the gap between the existing FT35 and FT60 models. The FT45 features the following key enhancements over the existing FT Series frame size designs, including the largest FT80 model:
 • IP65 (min.) environmental protection standard on all mounting configurations
 • Idler pulley design greatly simplifies motor installation and belt tensioning / maintenance
 • Grease zerk fitting allows re-greasing of nut assembly without having to disassemble the unit
 • Removable front seal bushing design greatly simplifies front seal maintenance / replacement
