6' Multi Bladder Air Shaft: Reliable Roll Handling for High-Speed Converting Applications

What is a 6' Multi Bladder Air Shaft?

A 6-inch Multi Bladder Air Shaft is a pneumatic expanding shaft specifically designed to hold rolls with a 6-inch inner core diameter. Equipped with multiple inflatable bladders, the shaft expands evenly inside the core when supplied with compressed air, providing a secure and balanced grip for winding, unwinding, slitting, laminating, and printing operations.

Its multi-bladder design ensures uniform expansion, making it ideal for demanding industrial applications where high torque transmission and precise roll handling are essential.

How Does a 6' Multi Bladder Air Shaft Work?

The shaft contains several high-quality rubber bladders positioned evenly around its circumference. When compressed air is introduced through the air valve, the bladders inflate simultaneously, causing the gripping lugs or strips to expand uniformly against the inside of the 6-inch core.

Once the production cycle is complete, the air is released, the bladders deflate, and the roll can be removed quickly and safely. This mechanism enables faster roll changes while maintaining consistent gripping performance.

Advantages of a 6' Multi Bladder Air Shaft

Superior Gripping Performance

The multi-bladder mechanism distributes gripping pressure evenly throughout the core, reducing slippage and ensuring stable roll rotation even at high speeds.

Faster Roll Changeovers

Quick pneumatic expansion and release minimize machine downtime, improving production efficiency.

Reduced Core Damage

Uniform pressure prevents localized stress on the core, extending core life and reducing material waste.

High Torque Capacity

Engineered to transmit high levels of torque, the shaft delivers reliable performance during demanding winding and unwinding operations.

Long Service Life

Manufactured using premium-grade steel, durable rubber bladders, and precision-engineered components, the shaft offers dependable performance with minimal maintenance.
