Inner wall is set of bellows, compressed at inner arm and expanded at outer arm, but degree of compression or expansion changes continuously as arm moves. Joint also used on diving suits and on manipulation sleeves for autoclaves and high-vacuum boxes, and as protective cover for articulated torque drives in hostile environments.
