The Industrial-Duty (ID) series of Glideforce linear actuators by Concentric International (formerly Iowa Export-Import) are powerful 12V DC gearmotors that use an acme screw drive or ball screw drive to move a shaft back and forth along its length. The shaft will hold its position even when unpowered. The versions with acme screw drives (part number LACTx-500Ax) can move loads up to 250 kgf [550 lbs or 2500 N] and withstand static loads up to 450 kgf [1000 lbs or 4500 N], while versions with more efficient ball screw drives (part number LACTx-1000Bx) can move loads up to 450 kgf [1000 lbs or 4500 N] and withstand static loads up to 1360 kgf [3000 lbs or 13,600 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, and a built-in overload clutch protects the actuator from excessive dynamic loads. The actuators have an all-steel frame and extension tube, and the entire case is sealed to protect against dust and water.

These actuators are available in a variety of stroke lengths, from 4″ to 24″, and with optional potentiometers that are linked to the shaft position
