Q. What is the working principle of air shaft?

A.A process for expanding a hollow core airshaft would use internal chambers that house air. Air is pumped into those chambers to expand the shaft. The shaft ends up getting much bigger in its diameter when it inflates, which locks the material roll position. One of the advantages of the expansion is uniformity, as the lock is minute and very secure. The material roll, therefore, is made to be held tightly, preventing it from slipping during rotation. As air pressure builds, it forces the mechanical elements inside the shaft to press against the roll and hence holds the roll intact without any kind of damage. This is achieved when air is deflated from the shaft, as it comes back into the original size, and it becomes easy to mount and take out the rolls with speed . The air shafts are lightweight but very strong; this would smoothen operation and precision as well . Perfect expansion enables very efficient handling of material. This is a proven principle. It ensures stable working. It allows uninterrupted operation. It works across different industrial fields.
