I'm not a mechanic and I know nothing of the topic. I am however looking to replace the legs on my computer desk with some electronic cylinders so that I can raise and lower the desk at the press of a button. The only issue is, I don't think it's a pneumatic cylinder that I'm looking for as their bore is quite small as is their stroke. They're also pretty bloody powerful and might launch the monitors in to the ceiling!
What is the name of the component I'm looking for? The description: a cylinder shaped device that extends in a single direction that can operate at the push of a button and can lift some weight (60-80kg would be ideal).
I think you get my drift... this is a small project I've been interested in screwing around with.
