Mechanical Chuck “MH-3 Type” (Leaf-Type Core Chuck)
A leaf-type mechanical chuck that securely grips cores from 2 inches and above — wide-area contact prevents deformation and ensures reliable performance.
The Pneumatic Mechanical Chuck eliminates the need for inserting and removing full-length shafts, while also preventing the end-face damage often caused by tapered cones. By gripping the core ID at both ends, it extends core reusability and supports stable, cost-effective operation. The MH-3 Type incorporates a leaf-type design that provides an exceptionally wide contact area, delivering secure torque transmission and contributing to high-quality, consistent winding. Key Features ・Reliable torque transmission with wide-area contact The leaf design offers greater surface contact than the MC-3 Type, preventing paper tube deformation and preserving product quality. ・Compatible with various core sizes Suitable for core inner diameters starting from 2 inches. ・Automation-ready A fixed end cap prevents sliding, making core insertion smoother and facilitating automated handling. Backed by decades of experience in unwinding and rewinding technology, Pneumatic Industries delivers proven reliability and long service life. For inquiries, please contact us: sales@pneumatic.co.jp
