The Light-Duty (LD) series of Glideforce linear actuators by Concentric International (formerly Iowa Export-Import) 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).

This 12 V light-duty (LD) linear actuator with a 10:1 gear reduction can lift loads up to 25 kgf [55 lbs or 250 N] and can withstand static loads up to 250 kgf [550 lbs or 2500 N]. It has a maximum speed of 28 mm/s [1.1″/s] at no load and 23 mm/s [0.9″/s] at the maximum load. Limit switches at each end make the actuator easy to control over its full range of motion. The shaft holds its position when unpowered.

These actuators are available in several gear ratios and a variety of stroke lengths, from 2″ to 12″, and with optional potentiometers that are linked to the shaft position, for use in feedback systems.
