Thread: Air Cylinder Question

Tweet

So I was on my town's trading post, and I saw that there was an American Cylinder 2" Bore, 20" Stroke, for $15. Sounded like a pretty good deal. So my question is, would this cylinder be too big or slow to run a trash can trauma. My plan would be to have something pop up from the chest. But if it would run too slow, then I wouldn't want to use it. But for the price, I may go ahead and buy it. If it runs too slow for a trash can trauma, what would be another good use for it?

Buy it tonight. If nothing else, you could resell it and use the profits for more projects.

Buy as many as you can get or afford to pay for and if they still have more go hit up the family. You can easily double, no triple, your money. And you can make a number of nice props out of a 20 inch throw cylinder. The 2 inch bore is larger than I usually use (1 to 1.5) it can come in handy for a heavier prop and it will still work for the TCT.

Buy it, i think the bigger the better for a TCT, and what an awesome price for 20" stroke!

I'm not sure if this is what you mean by it being too"slow" or not, but the speed that the shaft extends at can be made quicker by increasing the psi and it can be lowered by either lowering the psi, or using a flow control valve. That's what I've found anyway. If someone else could confirm that then that would be great.
Thanks

2 inch bore cylinder with 20 inches throw will move slower depending on the port openings. If they are 1/8 or 1/4 chances are it will be slow. If it has 3/8 thread then it will run faster but you need 3/8 hose otherwise a "bottleneck" will form.

You can speed up the cylinder about 3 times with a quick exhaust muffler. These attach to your cylinder directly and release air close to the cylinder instead of cycling down to the exhaust port of your solenoid.

If it is a single acting cylinder you would only need one quick exhaust. If it is double then 2 will be needed.

Thanks Industen, that makes a lot more sense than what i suggested, haha oh well
thanks again

Here is a video I made last year with quick exhausts. The speed of this cylinder was about 3 times slower before the quick exhausts. 1/4 threaded double acting with 1/4 quick connect hose.



Hope this helps

Industen, where did you buy those quick exhausts from? Those things seem to work awesome.

Aren't those just flow control fittings?

Yeah I plan on getting a quick exhaust for the cylinders. So I ended up with two cylinders. Both 20" Stroke. One is a 1 1/16" Bore, the other 2" with a 1/8 NPT and 1/4 NPT respectively. I'll probably use the 1 1/16th for a new TCT. Any ideas out there for the 2" bore?
