Contact usSeries 409 pneumatic expansion shafts enable rolls of any width to be clamped securely by means of expanding ledges, offer high torques and load capacity, and can be flexibly customised for various applications.
In contrast to conventional expansion couplings, which clamp an inflatable expansion ring directly against the core, these couplings use ribbed expansion leaves made of aluminium.
Pneumatically activated with individual expansion ledges. Low dead weight, similar to type A winding shaft.
Loads of up to 6 bar with easy maintenance and a low dead weight.
Pneumatically activated with continuous expansion ledges
Very lightweight, only to be activated when core is in place
Centric clamping via a slotted nut and mechanically activated with expansion leaves
Pneumatic knife shafts with continuous expansion ledges
When released, the spring allows the expansion lugs to contract.
When released, the spring allows the expansion lugs to contract.
Mechanically clamping centring ledges that respond to pressurisation of the cylinder chamber. The pneumatic expansion ledges also expand.
Perfectly centred clamping.
Standard shaft with flat bladders and a low dead weight
The leaves enable winding with thin cores. Coreless winding with web start clamping is also possible.
Standard shaft with central bladder
For higher reel weights and torques
