Precision and reliability in core engagement are essential in web converting and roll-handling operations. The Mechanical Expand Chuck offered by Cbbmachine delivers a practical solution for gripping and centering cores with mechanical force, without relying on air systems. This chuck is ideal for use in slitting, printing, laminating, and other applications requiring consistent torque transmission and quick roll changeovers.

This type of chuck functions through a mechanical expansion system, typically activated by a torque-driven or hand-operated mechanism. Once the shaft rotates, the internal expanding keys or lugs engage outward against the inner diameter of the core. This ensures a secure and evenly distributed hold, even under varying rotational speeds or roll weights.

A key advantage of the mechanical expand chuck is its ability to operate independently of compressed air. This eliminates the need for pneumatic infrastructure, reduces maintenance concerns related to air leaks, and provides a more stable engagement in areas where air supply is inconsistent or undesired. It's especially suitable for facilities operating in dusty, humid, or variable conditions where simplicity and durability are priorities.

The design is available in a range of core sizes and shaft diameters, making it adaptable to both new equipment and retrofit installations. Many models offer self-centering features, which not only reduce setup time but also help protect materials from edge damage or misalignment during high-speed runs.

In continuous production environments, quick roll changes are essential. The mechanical expand chuck streamlines this process with intuitive engagement and minimal tool requirements, helping to maintain uptime and reduce operator fatigue.

Whether working with paper, film, foil, or nonwovens, the chuck provides dependable torque transfer that protects against core slippage and ensures stable winding or unwinding throughout the job.
