An Airshaft Rubber Tube (also called an Inflatable bladder, Air bladder, or Expansion tube) is the core rubber component installed inside an air expansion shaft.
When compressed air is supplied through the air valve, the tube inflates and pushes the keys/lugs outward, gripping the paper core securely.
