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] for the LACT versions and 30 kgf [67 lbs or 300 N] for the GF23 versions. 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).

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. The table below shows all of the light-duty linear actuators we carry:

The following video demonstrates the speeds of the light-duty actuators:

Mounting brackets made from machined aluminum or stamped steel are available for attaching the actuators to a structure; two are required for each actuator (the aluminum brackets are sold individually while the steel brackets are sold in pairs).
