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. This version has a 8-inch stroke (7.8″ usable) and no feedback potentiometer.
