Applications, which cylinder shaft reciprocates under low fluid (air) pressure, represent the fluid power sector other main groups after hydraulics. These applications involve major parts such as pneumatic cylinders, valves and system components.
They are basic seal elements such as dust covered rod seals working on the shaft, piston seals which are mounted to the piston by working on the cylinder surface, and cushioning seals that can be allowed cushioning piston end of the stroke.
