Expanding Air Shafts

Double E air shafts are available in steel, aluminum, or lightweight carbon fiber.

All body types feature Double E's proprietary, longlasting internal bladder and tight-tolerance journal connection for easy maintenance.

1	Double E air shafts use the company's exclusive diamond pattern gripping lugs for gripping the core. The lugs' large surface area ensures extra core contact for even better performance.
2	The shaft's housing is made from steel or aircraft-grade aluminum (DG-2000), or from various grades of carbon fiber (DLB-2000) (depending on application requirements).
3	Special corded bladder material resists puncture and abrasion. As a result, the air shaft needs little, if any, maintenance and the shaft lasts longer.
4	The air shaft's journals are connected using high-strength flathead fasteners, a close tolerance fit, and deep insertion. Maintenance is rare, but when necessary it is quick and easy because a press-fit is not used.
5	The shaft's stainless steel air valve will never rust.
6	Airshaft journals are custom-manufactured to fit your machine.

DG-2000 Shafts (Dyna–Grip® Air Shafts)

Competing air shaft bladders are made with a common form of neoprene rubber which requires frequent replacement due to stretching and abrasion.
Double E air shaft lugs are available with a “diamond-grip” surface in steel, aluminum, or hard rubber, and have been field-proven to provide the maximum gripping performance possible.
Easy-maintenance journal connection - secured with flathead screws, a close tolerance fit, and deep insertion. Competing airshafts often use a tapered press fit, which requires a hydraulic press and heat to remove the journals. Bladder replacement on these shafts can take hours while the bladder of a Dyna–Grip airshaft can be changed in just a few minutes.
