The motor has 20:1 reduction gearbox that gives the actuator a dynamic load rating of 110 lbs (50 kg) and a maximum speed of 0.5 in/s (1.3 cm/s), and it is rated to withstand up to 500 lbs when not moving. Limit switches at each end make the actuator easy to control over its full range of motion, and the worm drive ensures that the shaft will hold its position even when unpowered.
