I am doing a school project an am looking for a pneumatic cylinder. What is the difference between rodless and not rodless cylinders? For my application, I need the piston like thing. Basically, what I am trying to do is use it to lift things, max of around 20 lbs. with a shaft size of 1.5'. Do any of you have any suggestions on where I can find them for the cheapest possible price?

Rodless are magnetically coupled to the load and have equal force in both directions. Cylinders with rods have less force in one direction becasue the amount of area exposed to the pressure is reduced by the cross-sectional area of the rod.
Rodless also are cleaner since they can be fully sealed

In concept, it could be under consistent acceleration, yet quite a few issues could decrease this. there'll consistently be some friction, yet no longer adequate for it to realize terminal velocity in 11 inches. the different restricting element is the bypass of the liquid or gas. If the source of tension or the inlet of the cylinder won't have the capacity to offer adequate bypass, the stress will drop. to make certain the (theoretical) acceleration use F = ma. Multiply the area of the bore by ability of the stress to get tension. you besides mght must be attentive to the mass of the piston and the burden. as quickly as you have desperate acceleration, use v = at to make certain velocity
