5mm/s 12V 660lbs Linear Actuator 4 Inch Stroke & Heavy Duty Waterproof Electric Piston Actuator for Automation in RV, Window and Car with Reverse Polarity Controller

My throttle cable on my excavator broke and a new one was $80. Plus it was a pain to install. This was $40 and I did a little redneck engineering and installed it on my excavator. Works great!! Now I can adjust the engine rpms with a touch of a button! Best mod I ever did!!

I have only had it for a week and only been able to use a few times because I had to get a reverse polarity switch which was supposed to come with it. It is shown in picture of items included and is also stated in description. Otherwise seems to work so far.

WORKS GREAT SUPER QUIET HEAVY DUTY SHOULD OF BOUGHT THIS YEARS AGO

For the price, wasn't sure what to expect but figured I would give it a try. Turns out, this is exactly what I needed to raise and lower the rear bed on my wife's 4-wheel "yard dog" she uses for yard work. Neighbor spent over $700.00 to accomplish same thing on his 4-wheel yard machine. His was hydraulic not electric but this one accomplishes the exact same thing at a fraction of the cost!It comes in different lengths so you need to determine the point of installation to determine the amount of "shaft" you need but that's easy enough, I used the 8" unit. Installation was very easy using the brackets provided with the unit; it bolted to the frame and then to a point on the lift bed. The two-way switch they provide accomplishes the needed ability to reverse the direction for up and down rather than a complicated controller seen with other units.Only had it a week or so now but so far.....I love it! Great product and transaction arriving on time and performing as advertised. I would strongly recommend it to anyone seeking similar need!!

Window for return closed on March 27 of 2025 and the actuator broke on April 3, 2025 not even being used to the full capacity.

It works but that's about it only lifting about 125 lbs after using for about an a hour the hole broke out of the cylinder at end where it hooks to small box blade. It is hollow inside but you get what you pay for. I would not recommend this. So I put a solid round sleeve in where it broke made it solid,maybe it will last a while longer.

I measured my old one and this one matched right up and works great. It’s only a matter of time to see how long it lasts. I use it on my snowblower attachment for my tractor, so it sees colder temps.

I have this tilting my 940 lbs solar array of 8 panels. Admittedly, the array is nicely balanced, so the motor does not have to work very hard, but this does the job with apparent ease. I took off a star since finding an enclosure to house the switch is going to be impossible. Will have to 3D print something - a cheap plastic enclosure should have been included.
