I want to fatigue-test some load cells. For instance, apply 100kg for 1 second 50,000 times and apply 1000kg 1000 times; total travel 10mm. In our local Ikea...

Peter, I'd recommend you stick with ordinary "shop air" pressure ~100 psi where everyday valves &fittings are happy. F=P*A tells you you need a large cylinder...

Hi Chuck ... OK. That's about 7 bar right? 7 atmopheres. 0.7MPa. I wasn't sure whether I should be sticking to 3 bar. ... Maybe. At the moment, our "press" has...

I also agree that pneumatics is going to be the easiest way. You will need a fairly large diameter piston to generate 1000kg of force using off the shelf air...
