Air Shaft

The Air Shaft inside is finished with special care so that the expanding tubular body will not be damaged by edges or burrs and this makes the shafts particularly reliable & durable in the long run with minimum maintenance. This shaft is manufactured with terminals according to customer's needs and therefore they can be adapted for various applications. The expanding effect is ensured by a main tubular body, which is resistant to high pressure, very stout & durable and by expanding against the shaft smooth polished internal flats causes the expanding grips to come out. The air inflation valve can be placed on one of the two ends of the roller holding the cores or on top of the terminals.
