Infantry Fighting Vehicle Elevation Actuator C7L265M

This electromechanical linear actuator is designed for high static holding requirements to improve stabilization accuracy and slew rates for existing and new turret applications.  This series of linear actuators has been designed to meet or exceed the demanding requirements of combat vehicle turret control applications.  They may be used for upgrading older hydraulic turrets or for new turret designs. Features include a brushless DC motor, linear ball screw output, self-lubricated spherical rod end bearings, external anti-rotation, and MIL-STD connectors.  Options included no-back and a flex shaft input for the manual drive.
