Air shaft consists of basic combination of body and journal, and materials have to be chosen according to working specifications.

Plates are inserted in a line in body and value of plate has to be equal to inner diameter of pipe. Lug is assembled in one-unified part with plate. Lug is operated by air-in and air-out and clamped on core inner side according to contraction and inflation of rubber tube.

Clamping power is being proportioned to air pressure.
Air-in and air-out air instantaneously done and lugs enter into shaft completely when air-out, then core can be exchanged very easily.
