Carbon Fiber Expanding Lug Shafts

Lightweight carbon fiber core shafts minimize shaft weight in unwind and rewind converting applications.

  • Meet OSHA standards for minimizing operator lifting injuries.
  • Replace heavy steel shafts without sacrificing strength or stiffness.
  • The Double E Group pioneered the use of carbon fiber as a shaft housing material in 1989. Tens of thousands of Double E Group carbon fiber shafts are being used by converters all over the world.
  • ShaftSafe®-Ready

DLB-2000 Carbon Fiber Core Shafts - Features, Advantages and Benefits

Carbon Fiber Shaft HousingLightweightFewer shaft handling injuries lower worker’s compensation expenses and
non-productive time

Meet regulations for single person lifting
Better ergonomicsNo maintenance or jamming, no contamination
Less deflectionReduced vibration and less roll bounce

Heavier roll weights
Higher critical speedMore throughput
Protective Outer SleeveProtects carbon fiber shaft from abrasionLonger carbon fiber shaft life
Proprietary BladderStretches less than traditional rubberDependable lug collapse ensures consistent, easy removal of shaft
from spent cores
More resistant to heat, puncture, & abrasionFar less bladder failure and minimized maintenance
Springless LugsNo springs to break and puncture bladderLonger bladder life; less maintenance
Diamond pattern gripping surface with
large surface area
Better grip with less slipping
Custom JournalsNo press fit facilitates journal removalBladder replacement, though rare, is quick and easy

Product Information

DLB-2000 Carbon Fiber Shaft Components

  1. Carbon fiber shafts have stainless steel air valves that will not corrode.
  2. Easy-access journal fastening system (no press fit).
  3. Gripping lugs.
  4. Proprietary corded polyprene bladder material minimizes bladder failure and subsequent maintenance.
  5. Carbon fiber shaft housing can provide stiffness and strength equal to steel at a fraction of the weight.
  6. Metal sleeve protects carbon fiber shaft housing from abrasion.
  7. Hardened steel journals custom made to fit any machine.

CF-1000 Dura-Light Non-Expanding Carbon Fiber Shafts (Through Shafts)

  • Used with core chucks to provide a lightweight shaft assembly

Dura-Light Mechanical Carbon Fiber Expanding Lug Shafts

  • For high speed and/or heavyweight applications requiring maximum torque capacity and minimum vibration.
  • Mechanical design provides the most powerful gripping force possible.
  • Activated by turning a crank (or impact wrench) that is inserted into the end of a journal.
  • Requires just five cranks for full expansion – lugs rise concentrically to center the carbon fiber shaft in the core, minimizing the roll bounce common with other types of expanding shafts.
  • Mechanical and Pneumatic/Mechanical Shafts are also available in Double E Group's traditional steel design.
