100% customizable expanding core chucks

The expanding chucks are torque activated chucks that use the movement of the reel to expand the gripping jaws elements in order to automatically block and centre the reel core.
The simple but innovative operating principle of these chucks, guarantees high performances even in dust-filled environments as the jaws expand just by rotating around a central cam.
All chucks are designed to avoid core damage and can be cleaned directly on roll stands.
Renova’s mechanical core chucks are 100% customizable and maintenance free.

  • Chuck base forged from a single piece
  • Case hardened steel and nickel coated
  • Simple design with very few parts
  • Heavy-duty and high-gripping jaws
  • Large jaws expansion even with very low torque
  • Self-expanding and self-locking in both directions of rotation
  • High load capacity
