Our pneumatic expanding shafts
Meet Ejematic’s pneumatic expanding shafts. Supported by one or two anchor points and personalised to facilitate maintenance and replacement operations
Why should you choose pneumatic expanding shafts?
Pneumatic expanding shafts simplify the coil changing process, saving time and increasing productivity. Thanks to its internal air bladder they allow the perfect core centring and gripping. When the bladder inflates, it activates the expansion ledges along the shaft which adapts to the roll’s diameter.
We manufacture lightweight and long-lasting expansive shafts, made of aluminium and stainless steel, with high resistant polyurethane air bladders. All our products come with a personalised exclusive system, which allows immediate maintenance and component replacements.
