Air Expanding Shafts

Product Details:

A Lug Type Expandable Shaft is a mechanical shaft used primarily in the winding and unwinding of rolls in industries like packaging, printing, converting, laminating, and paper. It holds and locks the core (typically a paper or plastic tube) of a roll in place using expandable lugs (keys) that extend outward when air pressure is applied.

• Construction: Typically made of steel or aluminum with internal bladders and outer lugs.

• Lugs: Hard metal lugs expand radially to grip the inside of the core.

• Air-Operated: Inflated using a hand pump or air compressor (3–6 bar pressure).

• Available Sizes: 1", 3", 6", or custom sizes depending on core ID.

• Quick core loading/unloading

• Firm grip without core damage

• Handles heavy loads

• Minimal roll slippage

• Balanced rotation at high speeds

Product Details:

A Lug Type Expanding Shaft is a mechanical shaft designed to hold and unwind/rewind rolls of web materials such as paper, plastic film, foil, textile, etc. It is commonly used in industries like printing, packaging, paper, plastic, and converting.

• Construction:

  • Central shaft made from steel or aluminum.

  • Expandable lugs (keys) embedded in the shaft body.

  • Lugs expand outwards when air pressure is applied or manually tightened.

• Operation:

  • Insert shaft into the core of the roll (typically 3", 6", or custom ID).

  • Inflate via air valve or use a mechanical expander.

  • Lugs grip the core firmly, allowing torque transmission without slippage.

• Types of Lugs:

  • Rubber Lugs – for delicate or low-tension applications.

  • Metal (Steel/Aluminum) Lugs – for heavy-duty or high-speed operations.

Product Details:

Leaf Type Air Expanding Shaft mainly consists of slotted base pipe, metal leaves with knurling/serration, rubber bladder, non-return valve and suitable journals.

This type of shaft can be used at unwind station, but mainly used at rewind stage for advantages like:

1.  Narrow width of core
2.  To prevent damage to thin cores (100 % support available to the core ID.)
3.  At times core-less winding is also possible
