Exlar FT45 Series electric rod-style linear actuators provide high thrust, speed and robustness in a compact form factor. They have a continuous force rating to 40,000 lbf, speeds to 60 in/sec and stroke lengths from 6 in. to 8 ft. The idler pulley design simplifies motor installation and belt tensioning/maintenance. A zerk fitting allows re-greasing of the nut assembly without having to disassemble the unit.
