This 12 V industrial-duty (ID) linear actuator uses an acme screw drive to lift loads up to 250 kgf [550 lbs or 2500 N] and withstand static loads up to 450 kgf [1000 lbs or 4500 N]. It has a maximum speed of 16.8 mm/s [0.66″/s] at no load and 14.3 mm/s [0.56″/s] at the maximum load. Limit switches at each end make the actuator easy to control over its full range of motion, and an overload clutch protects the actuator from being damaged by excessive loads. The shaft holds its position when unpowered. This version has a 4-inch stroke (3.5″ usable) and no feedback potentiometer.

This represents the maximum in-rush current when starting a stationary actuator. These actuators are NOT intended to be stalled, and they will not stall as long as maximum load ratings are respected.
This is a dynamic load rating. The actuator is rated to withstand 1000 lbs when not moving.
Or one minute of continuous operation in four minutes.
Total dust protection, water resistant.
