The actuators for scissor lifts and tilt tables from Air Springs (Meadowbank, New South Wales, Australia) attempt to eliminate one of the weakest links in pneumatic actuation: the seals in traditional cylinders. The Airstroke actuators are essentially — according to the company — heavy-duty balloons. They are available in a variety of sizes, with different components that control the shape and path of axial extension. The air springs offer side load flexibility and simplified attachment.
