ECO-WORTHY Heavy Duty 330lbs Solar Tracker Linear Actuator Multi-function (12V, 12)

Mine worked great. It does not make hardly any noise. It handles 4 - 100 watt panels with ease on my solar tracker. UPDATE: The system quit, including the Actuator and the controller that operates the Actuator. The seller said they would send me another one so I will have to wait and see.

Got these to replace a single one that was only rated half of theses I bought and used 2 instead of just one. So double the capacity and 2 instead of one youd think it would last, after about a month they started to get loud, 6 months later sounded like they were going to explode and at 8 months they quit within 4 days of each other. Only ran in and out 2 times a day and lifting a 1/4 of what there rated to do. DONT BUY !!!!

Used on dual swing gate, these are replacements for one failure and spare for the future. First set in use since 2017. Specs say 10mm per sec. Full travel (300mm) 30 sec. Right? One is 30, one is 55 sec. One is 70 sec. Same load, same voltage (13.5 avg solar), if this is no problem for you then good value, Im looking for faster and more consistent.

Very slow movement but lets chickens get out of the way. Works perfectly.

I built a solar tracker with 2 of these actuators. Regulated voltage, much less than 25% duty cycle (10 seconds every 10 minutes) with a perfectly balanced (125lb total weight), bearing rack. The panels can be easily moved with a single finger with less than 5 lbs pressure. One motor is shorting when moving in one direction but not the other as if the brushes are broken. These motors worked very well until it broke. Amp draw was less than 0.5a when running.. sure sounds like a build quality issue.

overall length. The operation length is stated but the length of the tube can change your mounting needs. The16 inch was useless for my needs as with brackets the tube was 22 inches itself. Thas needed useful information.

Using this to open a chain link gat that closes my chicken coop. It works well and has a lot of force. However, at least twice the motor has failed to rotate, it seems its bound up in the gearbox. I light tap on the motor and it starts turning, but it defeats the purpose if I have to go out there to check it every night.

Bought this to replace a cheap motor trim / tilt on my electric boat setup. Works perfect. A little loud but worth it.

I bought this to for a locking mechanism with a 50lb load. It takes about twice the time than listed to move the full travel. It also looks like it starts to bow under a compression load.

Using to open and close my chicken door.
