Associated Spring Raymond 104-410 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-410 is a medium heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 177.6 pounds and a spring rate of 188 pounds per inch. The 0.75-inch hole diameter, 0.375-inch rod diameter, and 2.5-inch free length make it a compact, high-force solution for applications where consistent return force and long service life under cyclic loading are required. Manufactured under ISO 9001 and ISO/TS 16949 quality standards, it is color-coded red to indicate medium heavy-duty duty rating for fast identification on the shop floor.

This die spring is suited for use in metal stamping, forming, and progressive die tooling in both production and maintenance environments. The red color coding follows industry-standard die spring classification, allowing tool and die makers, press operators, and maintenance technicians to quickly match replacement springs by duty rating. The 2.5-inch free length and 0.93-inch maximum deflection make this spring appropriate for installations with moderate stroke requirements in confined die spaces.

Key Features

• Chromium alloy steel construction for high fatigue resistance under cyclic loading
• Trapezoidal wire shape increases load capacity and deflection compared to round wire designs
• Maximum deflection load of 177.6 pounds with a spring rate of 188 pounds per inch
• Maximum deflection of 0.93 inches at full compression
• Red color coding identifies medium heavy-duty rating for quick field identification
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems, TUV Rheinland registered

Compatibility

Designed as an OEM-style replacement die spring for medium heavy-duty stamping dies and punch press tooling requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 2.5-inch free length.

Installation Notes

Die spring replacement is typically performed by tool and die makers or maintenance technicians during die maintenance or rebuild. Always relieve all press pressure and lock out the press before removing or installing die springs. Inspect the spring pocket and guide rod for wear or damage before installing a replacement. Do not compress the spring beyond its rated maximum deflection of 0.93 inches, as over-compression will shorten service life and may cause premature failure.
