Pneumatic Expanding Chucks
Pneumatic chucks used as pitching adapters increase the flexibility of your production. With only one shaft or winding bar it will be possible to convert a huge variety of different core diameters.

WISTEC pneumatic chuck for internal
core diameters of 350 mm (figure 2) |
Optionally it will be possible with a 76 mm shaft to expand other core diameters.

Other designs, fitted on one supporting axle, replace one complete pneumatic shaft. New: Supporting axle as far as Ø 40 mm !

Pneumatic spacer bushings with lugs are by far more superior as an adapter solution, compared with the simple expansion tires.

Offer the following advantages:
Clamping of 150 mm and 152 mm cores without any interchange.
- It is possible to transmit high torques.
- The forces do not effect the expansion segment, but effect the clamping lugs.
- This will result in a high and long lasting performance.
