Airblock is the line of expanding shafts with a central body in aluminium or steel, produced by both strips and keys execution. The strips positioned inside the slots of the shaft can be in rubber, PU or aluminium, while the keys positioned inside the special housings can be in rubber, or in aluminium, based on application needs.
The pins, made entirely according to the customer’s design, can be in steel, stainless steel or aluminium. It is also possible to apply different types of treatment on each journal, such as galvanizing and burnishing or heat treatments such as induction hardening. Expanding heads are a valid, simple and very flexible system of core locking and it is possible to quickly perform diameter changes of the cores on them, by using already existing shafts as base.
