Reliable expansion handled simply

Usable on a high number of processing machines

With just a low dead weight, the Vorwald expansion couplings are fastened on existing shafts, and expand pneumatically or mechanically. Their practical design enables simple handling. All expansion couplings can be optionally equipped with surface protection. Versions suitable for the food industry are also possible. The Vorwald expansion couplings can be converted particularly quickly to other core diameters.


Our specialist personnel will be delighted to advise you personally about the pneumatic and mechanical expansion couplings from Vorwald. You are welcome to download our product sheets free of charge and without obligation for further information.

Pneumatic expansion coupling
Freely moving
SPA series

Based on the proven design of the A series winding shaft, the pneumatic expansion couplings are equipped with freely moving expansion ledges, and can be used in both winding directions.

Pneumatic expansion coupling
Made to measure
SMB series

The Vorwald SMB series expansion couplings are based on the tried-and-tested design of the MB shafts. The length can be adapted as required, even to long lengths. The expansion couplings are only designed for "light" applications.

Pneumatic expansion coupling
609 series

Based on the 409 series expansion shaft, these expansion couplings are characterised by their light but extremely robust design. They are used in "harsh" applications.

Pneumatic expansion coupling
Light solution
SPM/SPZ series

Based on the principle of the L series expansion shaft, the SPM/SPZ series pneumatic expansion couplings are optimally suitable for narrow sheets and thin-walled cores.

Pneumatic expansion coupling
Gentle power
605 series

The robust but light Vorwald 605 series expansion couplings provide satisfactory service when core inner diameters are changed particularly often. They are optionally available with and without core stop collars.

Product data sheet
Mechanical expansion coupling
Inexpensive alternative
260 series

These simple and inexpensive mechanical expansion couplings are used for low to medium winding requirements. Special dimensions are possible on request.
