The Medium-Duty (MD) 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. All of the actuators in this category have a 20:1 gearbox reduction with all metal gears, which allows them to move loads up to 100 kgf [225 lbs or 1000 N] and gives them a maximum speed of between 1.0 and 1.5 cm/s [0.4 and 0.6 in/s], depending on the load. The shaft will hold its position even when unpowered and subjected to static loads up to 450 kgf [1000 lbs or 4500 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.

These actuators are available in a variety of stroke lengths, from 4″ to 12″, and with optional potentiometers that are linked to the shaft position, for use in feedback systems:

Actuator Type	Max Dynamic Load	No-Load Speed @ 12 V	Max-Load Speed @ 12 V	Current Draw @ 12 V	Nominal Stroke Length	With Feedback
Medium-Duty (MD)	100 kgf [225 lbs]	1.5 cm/s [0.58″/s]	1.0 cm/s [0.41″/s]	1.1 A – 4.6 A	4″	MD122004-P
					6″	MD122006-P
					8″	MD122008-P
					10″	MD122010-P
					12″	MD122012-P

Mounting brackets made from machined aluminum or stamped steel are available for attaching the actuators to a structure; two are required for each actuator.
