This 12 V linear actuator can be used in a variety of heavy-duty applications. The motor has 5:1 reduction gearbox that gives the actuator a dynamic load rating of 34 lbs (15 kg) and a maximum speed of 1.7 in/s (4.3 cm/s), and it is rated to withstand up to 450 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. This version has a 4-inch stroke and a built-in potentiometer for position feedback.
