LUG TYPE AIR SHAFT
lug_type_air_shaft
Shaft has one or two external air valves to inflate a single reinforced internal bladder that forces outward lugs. The shaft is normally made from either aluminum or steel bodies that depending on usage and requirements.

Lug type airshafts are strong and versatile, delivering superior performance in the widest range of converting unwind and rewind applications. Also, eliminate core damage, prevent roll slippage during fast startups and shutdowns, and minimize vibration at high web speeds.

Designed for light- to heavy-duty applications with 1" (25mm) to 12"(300mm) ID cores, the Air Lug shaft is often used in center unwind and rewind applications with either paper or steel cores.



 

LEAF TYPE AURSHAFT

Designed for a wide range of converting applications, these shafts are the best choice when using thin cores in your web process. If you want to minimize the deformation of core with air pressure, you are recommended to use Niika leaf type shaft.

With full-length external leaves, these shafts are particularly suited for delicate materials. Leaf Shafts are built tough, with bodies constructed of steel or aluminum, and internal tubes made of durable, hardwearing rubber.

This type of shaft should not be considered for use as a "differential type shaft" on slitters.
