inflating shaft

1.It is especially designed to wind at shaft core and unwind at single shaft in order to either meet customers' requirements for more higher tension and torque or bear more weighted materials.

From expanding of single air bag and key strips, shaft core will be clamped.

The central body is made from steel or aluminum; key strips are made from steel. Key strips can be made from other materials under customers' special requirements.

To meet our customers' special requirements, according to the drawings, we can make shaft head with all kinds of materials and surface treatments.

Due to its unique clamp system, air bag can be replaced after withdrawing the shaft head without adopting special tools.

The aluminium alloy body has a standard size and speculation (as shown in blew chart), and other sizes available upon request.



2. It applys to both winding and unwinding, and has the design of multiple air bags, in which their lengths are like that of air shaft body.

The central body is made from steel or aluminum; key strips can be made from rubber, aluminium, or polyurethane. They can be made from other materials under customers' special requirements.

Steel shaft head can be made according to customers' drawings, to meet any special requirements.

The aluminium alloy body has a standard size and speculation (as shown in blew chart), and other sizes are available upon request.

3. Thanks to the exclusive design of air shaft with key strips, air bag and expanding key strips are easily to replace without having to dismantle the shaft head.

When air bag swells by air, the outside diameter of air shafts expanding key strips expands to get stuck with inside diameter of paper tube.

The steel body has a standard size and speculation (as shown in blew chart), and other sizes available upon request.
