What is a Air picker?

An air picker is a mechanical part in which a hollow cylindrical rubber swells in a donut shape by injecting air and comes into contact with the inside of the work, and is held by the friction. It holds the inner surface of the work and scratches the contact part. It has a feature that cannot be attached. The one that holds the outer surface of the work by the same principle as the air picker is called an air gripper.
