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.

Each POSU shaft is customized to meet the exact needs of your processing requirements, and quality manufactured for long life, reduced maintenance and increased productivity.
