Dayton Lamina 9-1208-36 Die Spring 2 Inch Yellow Extra Heavy-duty

Product Description

The DAYTON LAMINA 9-1208-36 is an extra heavy-duty die spring designed for use in metal stamping dies, punch presses, and precision tooling fixtures. It features a 0.75 inch hole diameter, a 0.375 inch rod diameter, and a 2 inch free length. Manufactured from chromium-vanadium steel, this spring delivers a maximum deflection load of 400 pounds across a maximum deflection of 0.5 inches. The D-shaped wire cross-section and yellow color coding follow ISO 10243 standards, allowing toolmakers and die maintenance technicians to identify duty class at a glance during setup and changeovers.

This spring is suited for high-cycle stamping and forming applications in both automotive and general industrial tooling environments. The extra heavy-duty rating makes it appropriate for presses requiring high stripping forces or where space constraints demand a compact but powerful spring element. It fits standard die sets with 0.75 inch spring pockets and 0.375 inch guide rods. The 25 percent maximum operating deflection guideline should be observed to maintain spring life within design parameters.

Key Features

• Extra heavy-duty duty rating with a 400 pound maximum deflection load
• Chromium-vanadium steel construction for high fatigue resistance in repetitive-cycle tooling
• D-shaped wire profile provides consistent seating and reduces rotation in the pocket
• Yellow color coding per ISO 10243 for fast visual duty-class identification
• Travel to solid load of 0.59 inches with 0.5 inch maximum recommended deflection
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an OEM-style replacement or direct drop-in die spring for standard tooling applications using 0.75 inch spring pockets and 0.375 inch guide rods conforming to ISO 10243 specifications.

Installation Notes

Die springs of this type are installed and serviced by tool and die makers or press maintenance technicians. Before servicing a die set, lock out and tag out the press per OSHA LOTO procedures and relieve all stored energy. Inspect the spring pocket and guide rod for wear or misalignment before installing a replacement spring. Do not exceed the rated maximum operating deflection of 25 percent, as over-deflection will significantly reduce spring fatigue life.
