Double E provides expanding core shafts of all types, including lightweight carbon fiber lug shafts, lightweight aluminum strip (external gripping element) shafts, mechanical shafts for high speeds or heavy roll weights, and differential rewinding shafts.
Carbon fiber expanding shafts are lightweight alternatives to heavy steel or aluminum shafts. These shafts provide the following benefits:
Carbon fiber housing provides the strength of steel at a fraction of the weight.
Housing sleeved in metal to protect against abrasion.
All Double E bladder shafts feature a special corded polyprene bladder expands with air to grip core ID. Robust bladder material reduces bladder failure and minimizes maintenance.
Deep journal insertion and a close tolerance fit ensure easy access when necessary.
