Six-Blade Plate Type Air-Powered Expansion Shaft‌

Uniform Force Distribution: Expansion is achieved by multiple plates (six plates). These plates, acting as expansion elements, have fulcrums distributed throughout the shaft circumference, resulting in more even force distribution and preventing excessive clamping force on one side that could cause roll deformation.

Rapid Expansion/Contraction: Activated by air pressure, expansion or contraction is typically completed within seconds, significantly reducing downtime for roll changes.

High-Precision Applications: The plate-type structure is particularly suitable for thin and light materials such as films, electronic materials, and non-woven fabrics, where high requirements for roll roundness, vibration, and tension uniformity are necessary.

Rugged Material Structure: The shaft is typically made of steel or aluminum alloy, and the outer expansion plates are aluminum alloy blades, offering advantages such as wear resistance and lightweight construction.

Wrapping/Rewinding Equipment Applications: Suitable for industries such as printing, slitting, rewinding, film, paper, and composite materials, improving clamping stability and roll change efficiency.
