• Concentric clamping of even the narrowest
cores by proven mechanical Vorwald expansion
system, thus ensures steady running of the reels,
even with heavy reels and high web speeds
• Transmission of highest torques by pneumatic
expansion ledges
• Special dimensions possible on inquiry
• Simple pneumatic actuation of the
expansion mechanism
• Quick expansion and release, because
only small amounts of air are required
• High true running accuracy
• Minimised bending by
maximised moments of inertia
• Very little maintenance required
Available shaft diameters
in the range from 148 to 600 mm
