Re: New to Pneumatics - What to get?
Something that hasn't been brought up in this thread is the design ideas that you need to have when using pneumatics.
Obviously you'll need to know how to calculate the force that pistons can exert at a given pressure.
The important thing that is easy to mess up, is you need to be sure to design your mechanical/pneumatic system to not put any side-loading on the piston rod, or you can risk destroying the piston.
Essentially design your system so it is fully constrained except for one axis of motion, and then add your piston there. If your system has more than one degree of freedom, you risk bending your piston.
