Expansion couplings
Expansion couplings optimise winding processes by enabling rapid process changeovers, delivering high torque transmission and offering easy handling. They are suitable for a wide range of materials and diameters.
6 Products
Series SPM and series SPZ pneumatic expansion couplings
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.
Series SPA expansion coupling
Pneumatically activated with individual expansion ledges. Low dead weight, similar to type A winding shaft.
Series SMB expansion coupling
Loads of up to 6 bar with easy maintenance and a low dead weight.
Series 609 pneumatic expansion coupling
Pneumatically activated with continuous expansion ledges
Series 605 pneumatic expansion coupling
Very lightweight, only to be activated when core is in place
Series 260 mechanical expansion coupling
Centric clamping via a slotted nut and mechanically activated with expansion leaves
