furniture automation
Hi! I recently started looking into electric linear actuators and have come across a huge selection of models—from compact options for furniture automation to powerful industrial devices. But I'm still not entirely sure how to choose the right one for my project. For example, how important is it to consider the load and stroke when selecting an actuator, and how do I determine the optimal voltage—12V, 24V, or 36V? I'm also curious if there's a noticeable difference in reliability and noise levels between worm-gear and screw-type actuators. Please share your experiences if you've encountered this.
I faced the same issue some time ago and can share my experience. When choosing an electric linear actuator for my project, the first thing I did was determine the load and required stroke—these are truly key parameters. For lightweight structures, such as furniture automation or small mechanisms, I used compact actuators with a stroke of up to 200 mm and a load capacity of up to 150–200 kg, while for heavier projects, I chose more powerful models. Regarding voltage, I noticed that 12 V is great for low-power systems, 24 V provides stable operation under medium loads, and 36 V is already used for industrial equipment. I'd also like to point out the difference between worm and screw actuators: worm actuators are more reliable and can hold the load even when the power is disconnected, but they operate slightly slower and louder. Screw actuators are generally quieter and faster, but their holding capacity without power is lower. For my project, I chose a 24V screw drive—its combination of smooth operation, low noise, and sufficient power for my mechanism proved to be optimal. As a result, the device operates reliably, without jerking, and handles the load reliably.
