That's not a linear actuator. It's a "rod/screw actuator", an ordinary electric motor driving a screw on which rides a threaded block carrying an extension rod. You should be able to build something like that pretty quick with hand tools, never mind a machine shop.

The only GM alternator bearings I've had fail, failed when I over reved the engine to 8,000 RPM, which tried to turn the alternators at
16,000 RPM. The stock engine red lined at 5,200 RPM, which was still over bearing's 10,000 RPM rated limit. This was in the early '70s, in a souped up '66 GTO.
Thank you for all of the replies. Does anyone know where I can find a small electric motor like this? I have looked at Digi-Key, Mouser, etc., but I must be missing it. I don't mind trying to build this as long as I can find a similar motor (in size). Any leads?

Looks more sophisticated than your reference, but along the same lines. 6-12 volts 3" travel the motor has a 50 pulse optical speed encoder.
Go to a local hobby shop where they sell RC airplanes, model trains, and etc. If they don't have one they can probably tell you who does.
Good Luck! Rich
I wonder if anyone is considering bringing back sailing ships. They don't use _ANY_ fuel! Well, except for maneuvering and if you get caught in the Doldrums.

Kites for container ships, looks promising, the global temp will now only go up by 3.9998C instead of up to 4C

Maybe, maybe not, but the guy who owns the ship can probably save a penny or two on fuel for the trip.
Cheers! Rich
Neat idea - been using it myself to power my kayak. I have a 2.5, 14,
24 square foot kite depending on conditions. I can make my displacement hull speed of ~5 knots under wind power and up to 45 degrees off the wind sailing downwind.I get a lot of comments and stop traffic with it. It works best in open ocean away from trees but I can also use it on big lakes, and rivers by flying the kite high enough. I steer by putting a little drag on one or the other side with a paddle. Been at it 5 years now.
there
That is an interesting technique.
