Associated Spring Raymond 104-816 Die Spring Red Medium Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 104-816 is a medium heavy-duty die spring designed for use in metal stamping dies, punch presses, and other high-cycle tooling applications where consistent, repeatable force is required. It features a 2 inch hole diameter, a 1 inch rod diameter, and a 4 inch free length. The trapezoidal wire cross-section increases the active coil volume compared to round wire, delivering a higher load capacity within a given envelope. The spring is manufactured from chromium alloy steel and color-coded red per ISO standards to identify its medium heavy-duty duty rating at a glance.

This die spring is suited for installation in production tooling setups found in metal fabrication shops, stamping facilities, and tool-and-die operations. It is mounted over a guide rod or inside a spring pocket in a die set, providing controlled return force on punches, stripper plates, or cams. The red duty rating positions it between light and extra-heavy springs, making it a common selection for moderate-to-high load tooling where deflection control and fatigue life are critical requirements.

Key Features

• Trapezoidal wire shape increases load-bearing coil volume for higher capacity in a compact form factor
• Maximum deflection load of 982.7 pounds at full rated deflection
• Maximum deflection of 1.48 inches with a spring rate of 664 pounds per inch
• Chromium alloy steel construction for fatigue resistance in high-cycle tooling environments
• Red color code identifies medium heavy-duty duty rating per ISO die spring standards
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as a standard ISO-profile die spring suitable for guide-rod mounting in metal stamping dies and punch press tooling requiring a 2 inch hole diameter and 1 inch rod diameter spring pocket.

Installation Notes

Die springs are installed and serviced by tool-and-die makers, press operators, and maintenance technicians. Always de-energize and lock out the press before removing or installing die components. Ensure the guide rod and spring pocket dimensions match the rod diameter and hole diameter of the spring before installation. Do not compress the spring beyond its rated maximum deflection, as over-compression significantly reduces fatigue life and can cause premature failure.
