I bought a cheap linear actuator from Aliexpress and wondered what sort of dodgy de-rating factor I should apply...





I have tested it with a 10kg weight and it seems fine, speed isn't measurably changed from no load, but I am having a hard time believing that it is rated for over 100kg. The intended use is for lifting and dropping a projector with a total weight (projector and carrier bracket) of about 12-14kg. Am I likely to be safe just using this to direct drive it? (Straight pull for actuator)


I could put a counterweight in as well to reduce the lifting power required, but don't want to bother if I am safe, or very likely to be safe.


Cheers _ N

Don't see why not, looks like you have good safety margin there. See how you go with 30kg.
