In modern material unwinding and rewinding processes, precision holding is not optional—it's foundational. The Mechanical Expand Chuck offered by Cbbmachine is built to meet the demands of roll-based operations that require consistent, damage-free clamping without complicated air systems. Designed for simple installation and mechanical activation, this chuck ensures maximum torque transmission while reducing core deformation.

Its working principle revolves around expanding mechanical elements that create a firm hold on the core from the inside out. This enables secure clamping across varying core diameters, making it suitable for both new production lines and retrofit applications. By eliminating slippage, it supports tension integrity throughout the cycle—key for industries like packaging, printing, laminating, and nonwovens.

One major benefit is its independence from air supply systems. Where pneumatic chucks may require routine checks or auxiliary equipment, mechanical expand chucks offer a more self-contained and dependable solution. This makes them especially useful in mobile or remote settings where compressed air may not be readily available.

Durability is another key factor. The chuck's internal components are constructed with high-strength alloys and precision-machined parts that resist fatigue under constant load. It requires minimal maintenance and provides a long service life, all while maintaining the ability to quickly engage and release cores with manual effort only.

Operationally, mechanical chucks also speed up core changes. Their straightforward design reduces the risk of installation errors or alignment issues, helping machine operators maintain consistent cycle times with minimal training. For businesses balancing flexibility with output, that kind of reliability supports daily productivity.
