DLB2000 Carbon Fiber Expanding Core Shafts

DLB2000 Carbon Fiber Expanding Core Shafts, for unwind and rewind applications.
CF1000 Carbon Fiber Through Shafts, Non-expanding core shafts are available for through-roll support using air chucks.
Carbon fiber shaft body provides the strength of steel at a fraction of the weight.
Proprietary corded polyprene internal bladder expands with air to force the lugs to grip the inner diameter of the core. The special bladder material reduces bladder failure and minimizes maintenance.
Deep journal insertion and a close tolerance fit ensure easy access when necessary.

SR2000 External Element (Strip Design) Core Shaft
 
For multiple slit rewinding with aluminium or steel body.
Simple clamping unit secures bladder/gripping element assembly for easy maintenance.
Durable hard rubber grippers offer excellent core grip.
Protective Teflon strip covers bladder to reduce liklihood of bladder failure.
Brass air valve resists corrosion.

RS2000 Carbon Fiber Expanding Reel Spool Shaft

Much lighter in weight than expanding steel shafts; requires far less driving energy.
Carbon fiber housing allows faster critical speeds without increasing core size.
Pneumatic/mechanical system ensures true concentric expansion.
