Dayton Lamina 9-2008-36 Die Spring Extra Heavy-duty Yellow

Product Description

The DAYTON LAMINA 9-2008-36 is an extra heavy-duty die spring designed for use in stamping dies, punch presses, and precision tooling applications. Built from chromium-vanadium steel with a D-shaped wire profile, it delivers high load capacity and consistent return force under repeated compression cycles. The spring features a 1-1/4 inch hole diameter, a 5/8 inch rod diameter, and a 2 inch free length. Maximum deflection load is 989.00 pounds at 0.5000 inches of deflection, with a maximum operating deflection of 25 percent. The yellow color coding identifies the extra heavy-duty rating per ISO 10243 standards. This part is installed by tool and die makers, press room technicians, and industrial maintenance personnel.

This die spring is suited for high-cycle stamping and forming tooling where consistent spring force and long service life are required. Its chromium-vanadium steel construction resists fatigue under sustained load cycling, making it appropriate for production stamping dies, injection mold tooling, and fixture applications. The D-shaped wire cross-section maximizes material volume within the coil, contributing to the extra heavy-duty load rating. It is packaged individually and sold as a single unit.

Key Features

• Extra heavy-duty duty rating with 989.00-pound maximum deflection load
• Chromium-vanadium steel construction for fatigue resistance in high-cycle applications
• D-shaped wire profile maximizes load capacity within the coil envelope
• 1-1/4 inch hole diameter and 5/8 inch rod diameter for precise die alignment
• Yellow color coding per ISO 10243 for quick duty-rating identification
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as a replacement or standard die spring for stamping dies, punch press tooling, and precision fixture assemblies requiring a 1-1/4 inch hole diameter, 5/8 inch rod diameter, and 2 inch free length in an extra heavy-duty application.

Installation Notes

Installation is performed by tool and die makers or press room maintenance technicians. Ensure the press or tooling assembly is fully de-energized and all stored mechanical energy is released before removing or installing die springs. Do not exceed the maximum operating deflection of 25 percent of free length during service, as over-compression accelerates fatigue and reduces service life. Inspect the spring seat and guide rod for wear or misalignment before installation.
