DasMorine 8" Stroke Linear Actuator with Mounting Bracket for Recliner TV Table Lift Massage Bed Electric Sofa,Linear Electric Actuator 225LBS Load Capacity 10mm/s Speed 12V DC,Black,Indoor Outdoor

Thank you so much worked first time

The media could not be loaded.

Works perfectly easy to install great for the job .

The media could not be loaded.  Whilst there are many things bad about globalisation easy access to things that only a few years ago were speciality items at a reasonable price is not one of them. This actuator is a case in point.Now, this might not be the kind of thing most people might look for or want, but if you are a 'Maker' or need to replace an actuator that requires this extension then this is a pretty good option.The machine itself is simple to operate. In a nutshell it's a DC motor that drives a gear that turns a threaded bar inside the rod to extend or retract. Simply changing the polarity reverses the direction. You can do this manually, with old school relays or electronically if you have the knowledge.Quite well made although not full industrial grade. For light use or for the hobby maker this will be fine.I tested this in my workshop with a 12V battery and it worked well. Plenty of power and isn't over noisy. Certainly it's not going to be an issue give that it's going to be used infrequently as a means to rotate a worktop tool into place.I'm sure there are a gazillion uses for one of these and no doubt a load of YouTube Makers with plenty of projects to demonstrate similar.I've had a look around Amazon and there are loads of variations on this theme and thus you need to check the throw needed and the price. I suspect they are all pretty similar for a given extension.Overall, a cool bit of kit to make some fun stuff in your workshop.

Good strong brackets and fixings make this super easy to implement and 12v is super easy to supply using any number of cheap and easy DC sources. Can have this up and running in minutes with very little work.

This DasMorine 4" Stroke Linear Actuator with Mounting Bracket for Recliner TV Table Lift Massage Bed Electric Sofa,Linear Electric Actuator 225LBS Load Capacity 10mm/s Speed 12V DC,Black,Indoor Outdoor is great! Nice quality! Easy to use! Easy to install! Works perfectly good value for money

This is a clean looking actuator, perfect for projects where it isn't necessary to hide this away from sight.Comes with parts to mount both ends and has a very strong lift force.i have tested it with power as low as 5v .5A and up to 12V 3A , The speed varies based on the power input.The way its made will not allow any unwanted movement if this was to lose power, it locks in place to where its left. There is no exact position setting unless you use triggers or programmatically time the movements. So its must always have power to allow use, i.e probably not wise to use on a door/exit.

This is a nice unit if you’ve got a specific project in mind that requires an actuator with a 10 cm stroke. Honestly, this thing is way more powerful than I'd ever be able to fully utilise or need for my projects. The number of projects you could actually use this on is pretty huge and only limited by your imagination & building capabilities as it can even be implemented into low voltage solar systems if you wanted to open, close or adjust something in a shed, greenhouse or garden for example.It's great that it comes with the mounting brackets for attaching this to a surface and it's a simple device to use when it comes to controlling it. To extend the actuator, just feed positive into the black wire and negative into the red wire, then reverse that if you want to pull the actuator back again. You can of course get fancy with the circuit controlling it, but that's the gist of it.Contrary to what other reviewers are suggesting, this is nowhere near silent, it won’t go unnoticed without making conscious design choices or compromises to reduce the noise produced. At the max voltage of 12V, it makes a distinct and loud mechanical whirring noise that is audible from the other side of a room with it in the open sitting on a desk.If high speed & power isn’t the goal you can just drop the voltage down until you’re satisfied with the audio level and it genuinely does get reasonably quiet at 2.5 volts which is the lowest I was able to run this at before it would occasionally stall out. I was literally able to run this thing on a pair of NiMH AAA batteries in series from a tiny battery pack without any load. Of course, you’re losing a lot of the strength by undervolting it, but many projects won’t ever need the 900N from the full 12V from this and running lower voltages lets you control the speed and noise.For reference, I ran a super unscientific test by putting my phone 10cm from the motor on the actuator and measured the decibels. Each of the measurements was taken with no load at different voltages on the return stroke. The results of my testing were as follows: 65dB at 12v, 59dB at 8V, 55dB at 5V, 52dB at 3.5V and 46dB at 2.5V. Obviously building the actuator into an enclosure or something will reduce or dampen the noise to a certain degree but I wanted to correct some of the misinformation present in the reviews and the description.Other than the noise, this is an excellent product that has plenty of power at the rated voltage and amperage. The built-in limit switches make it super easy to implement into basic electronic circuits and if you’re not into electronic projects you can control this with a single DTDP (double throw, double pole) switch that will give you fine control of the actuator in both directions. I’m very happy to recommend it, as long as you don't expect this to actually run at super quiet sound levels.
