Anyone Using Actuators for Hidden TV Lift Mechanism?

[Erik5]

Planning to make a pop-up TV lift from cabinet. TV is 55 inch, about 18 kg. Want clean vertical movement, no visible rails. Thinking about linear motion actuators. How many do I need — one strong or two smaller? Is 1000N per actuator okay? What stroke length for 80 cm lift? Worried about speed and stability. Share your experience please!

Hidden TV lifts are cool projects. For 55″ TV I recommend two synchronized actuators — one on each side — much more stable than single in the middle. 1000N each is plenty (I used 1000N and had no issues with 22 kg panel). Stroke around 800–900 mm depending on your cabinet depth. Very smooth movement. Check this site for options: linear motion actuators https://www.progressiveautomations.com/en-eu/pages/actuators . They have models with built-in feedback for perfect sync. I used their control box with remote. Speed is adjustable, noise is low.

TV lift mechanisms are getting more popular in living rooms. Using two actuators instead of one definitely improves balance and reduces wobble.
