That is a very cryptic question, but they do manufacture pneumatic cylinders where the piston has a very strong magnet which moves back and forth with the piston. A sleeve outside the cylinder has a magnet too, and this couples the sleeve to the piston, transferring motion. The coupling of the magnets can be anywhere from a few pounds to over 100 pounds determined by the diameter and sizes of the magnets. They can be quite strong actually.
Another system has a loop (metal band) that attaches to the moving piece and the piston with seals on each end of the air chamber. The magnetic design requires no seals.

Heavy truck suspension systems utilize pneumatics. They are more like ballloons than the conventional steel cylinders but they do have a round cross section and have a length that can vary depending on the air pressure/ load equilibrium.

Pneumatic cylinders are infamous for being jerky and erratic of their operation. If there is the slightest little bit of extra beneficial friction interior the piston, rings, seals or misalignment of the areas there could be problems. a loss of adequate air volume or tension is additionally a situation. If the cylinder is border line in terms of length, which could additionally deliver approximately problems. to that end, the ramp's moving areas is additionally binding, desire lubrication or alternative.
