There isn't much to it actually. Estimate the weight of the z-axis and then find an aircylinder that can deliver the force required to hold that weight. Make sure you do the calculations for a lower pressure than what you have, so i'm going to run 8 or 10 bar in my shop, so i designed the counterweightsystem to run at 5-6 bar, this gives me the option to increase the pressure if the z-axis is heaver than estimated...
