A long-life air cylinder (linear actuator) is well suited for medical applications requiring long life and corrosion resistance. The 1-in. bore cylinders are made from brass or stainless steel with a clevis tail. Two composite bushings, one in the nose and the other in the tail assembly, support the piston rod. These separated bushings support most couples induced by side loads and stress reversals, thus minimizing stress raisers, a source of early failure in cylinders. It does not need lubed air. The extension-force factor is 0.78, and 0.70 in retraction.
