8 Inch Stroke Linear Actuator 12V Heavy Duty 440lbs/2000N IP65 Waterproof Electric Actuator Speed 0.31"/sec with Mounting Brackets

I got these for a vault door project, they will be activating 12 3/4' steel rods that lock the door closed. I used two for the sides and two for the top & bottom locks, all operating in parallel. These only have a 4' stroke, but the operation is identical on all units. Love the power and speed of the motors, they operate until the end of the stroke, then will stop. Reverse is the same, I plan to use a remote-control device to operate the movement. I would and will use these motors again on future projects.

Awesome product.

Just wasn't long enough for what he wanted to use it for. But will probulary use it on another project....

It's thin but it works well. I used it to change a hydraulic one.

Buyer beware. This actuator has a duty cycle of 2 minutes on and 18 minutes off. This was not disclosed on the sellers page. Update: The seller gladly refunded my money and modified thier description to be more accurate for future buyers. I was impressed on how quickly they resolved it for me. I was able to find an actuator that met the spec, but at a higher cost which is only fair.

I used two of these linear actuators to raise and lower part of this toolbox so that it can fit into my trailer. The actuators are very powerful and easily lift the 100 lb upper structure.

Great value for the price
