Dayton Lamina 9-1204-26 Die Spring Red Heavy-duty

Product Description

The DAYTON LAMINA 9-1204-26 is a heavy-duty die spring engineered for use in metal stamping, forming, and punch press tooling. It features a 0.75-inch hole diameter, a 0.375-inch rod diameter, and a 1-inch free length. Wound from chromium-vanadium steel and color-coded red to indicate heavy-duty load class, this spring delivers a maximum deflection load of 405 pounds and a maximum deflection of 0.31 inches. The D-shaped wire profile provides consistent force distribution and improved seating in standard die sets. It is installed by tool and die makers, press operators, and maintenance technicians working in precision fabrication environments.

This die spring is suited for industrial stamping dies, injection mold tooling, and progressive die assemblies where controlled spring force and repeatable deflection are required. The red color coding follows international die spring standards, making it straightforward to identify load class during maintenance and changeover. It is appropriate for both light-production and high-cycle tooling applications where dimensional consistency matters.

Key Features

• Heavy-duty load class with a maximum deflection load of 405 pounds
• Chromium-vanadium steel construction for fatigue resistance and long cycle life
• D-shaped wire profile ensures stable seating and consistent force output
• Maximum operating deflection of 30 percent (0.31 inches) of free length
• Red color coding identifies heavy-duty load class per international standards
• Meets ISO 10243, ISO 9001:2015, and NAAMS specifications

Compatibility

Designed as an OEM-style replacement or drop-in die spring for standard heavy-duty die sets requiring a 0.75-inch hole diameter and 0.375-inch rod diameter with a 1-inch free length.

Installation Notes

Die springs are installed by tool and die makers and press maintenance technicians. Always de-energize and lock out the press before removing or replacing any die components. Do not compress the spring beyond its rated maximum deflection, as over-compression can cause permanent set or premature failure. Verify hole and rod diameter clearances against the die set specification before installation.
