# 3' Multi Bladder Air Shaft: High-Performance Roll Handling for Precision Converting
## What is a 3' Multi Bladder Air Shaft?
A **3' Multi Bladder Air Shaft** is a pneumatic expanding shaft designed to securely grip rolls with a **3-inch (76.2 mm) inner core diameter**. Using multiple inflatable rubber bladders, the shaft expands evenly inside the core to provide a firm, balanced, and slip-free grip during winding and unwinding operations.
This type of air shaft is widely used in converting industries where precision, high-speed performance, and quick roll changes are essential. Its multi-bladder design ensures uniform pressure distribution, improving both productivity and roll handling efficiency.
## How Does a 3' Multi Bladder Air Shaft Work?
The shaft contains several high-quality inflatable rubber bladders positioned around its body. When compressed air is supplied through the air valve, the bladders inflate simultaneously, pushing the expanding lugs or strips outward to grip the inner surface of the 3-inch core.
Once production is complete, the air is released, the bladders deflate, and the shaft contracts, allowing the roll to be removed quickly and safely. This pneumatic mechanism minimizes downtime while ensuring secure roll handling throughout the production process.
## Key Features
