12V DC Linear Actuators: 11.81'' Stroke, 17.72'' Retract, 28.53'' Extend, Acme Drive

The Light-Duty LD series of Glideforce linear actuators by Concentric International are 12V DC gearmotors that use a lead screw to move a shaft back and forth along its length. The shaft will hold its position even when unpowered and subjected to static loads up to 250 kgf 550 lbs or 2500 N. Two limit switches safely stop the motor at either end of its range, while integrated diodes allow it to reverse direction after reaching a limit point if the supplied voltage is reversed. The actuators have an all-aluminum frame and extension tube, and the entire case is sealed to protect against dust and water rated IP65.
