Summary

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.
Double E pioneered the use of carbon fiber as a shaft housing material in 1989. Tens of thousands of Double E carbon fiber shafts are being used by converters all over the world.

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

FEATURE	ADVANTAGE	BENEFIT
Carbon Fiber Shaft Housing	Lightweight	Fewer shaft handling injuries lower worker’s compensation expenses and non-productive time. Meet regulations for single person lifting.
Carbon Fiber Shaft Housing	Better ergonomics	No maintenance or jamming, no contamination.
	Less deflection	Reduced vibration and less roll bounce. Heavier roll weights.
	Higher critical speed	More throughput.
Protective Outer Sleeve	Protects carbon fiber shaft from abrasion.	Longer carbon fiber shaft life.
Proprietary Bladder	Stretches less than traditional rubber.	Dependable lug collapse ensures consistent, easy removal of shaft from spent cores
Proprietary Bladder	More resistant to heat, puncture, and abrasion.	Far less bladder failure and minimized maintenance.
Springless Lugs	No springs to break and puncture bladder.	Longer bladder life; less maintenance
Springless Lugs	Diamond pattern gripping surface with large surface area	Better grip with less slipping.
Custom Journals	No press fit facilitates journal removal.	Bladder replacement, though rare, is quick and easy.

DLB-2000 Carbon Fiber Shaft Components

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

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

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's traditional steel design.
