Associated Spring Raymond 204-810 Die Spring 2.5 in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-810 is a heavy-duty die spring designed for use in stamping dies, punch presses, and other high-cycle tooling applications. This spring features a trapezoidal wire cross-section, which increases the active coil volume compared to round-wire springs and delivers a maximum deflection load of 5016 newtons at full compression. Manufactured from chromium alloy steel and finished in blue, it carries a free length of 2.5 inches (64 millimeters) with a maximum deflection of 24 millimeters. Toolmakers, die setters, and precision fabrication shops are the primary installers.

This die spring is suited for use in metal stamping and forming tooling, injection mold assemblies, and industrial press applications requiring consistent, predictable spring force over high cycle counts. The blue color coding identifies this spring as a heavy-load classification under ISO 10243 standards, making spring selection and replacement straightforward on the shop floor. It fits applications calling for a 50-millimeter hole diameter and a 25-millimeter rod diameter.

Key Features

• Trapezoidal wire shape maximizes active coil volume for higher load capacity within the same envelope
• Blue color coding denotes heavy-load classification per ISO 10243
• Chromium alloy steel construction for durability in high-cycle press and die environments
• Maximum deflection load of 5016 newtons at 24 millimeters of travel
• Spring rate of 1193.42 newtons per millimeter for predictable, linear force output
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a direct-fit die spring for tooling applications requiring a 50-millimeter hole diameter, a 25-millimeter rod diameter, and a 2.5-inch free length, conforming to ISO 10243 heavy-load specifications.

Installation Notes

Die springs are typically installed and serviced by toolmakers or die setters with the press locked out and de-energized per OSHA lockout/tagout procedures. Ensure the spring bore and rod diameters match the housing precisely before seating; do not compress the spring beyond its rated maximum deflection of 24 millimeters. Inspect the spring for set or cracking at scheduled maintenance intervals and replace as a matched set when used in multi-spring tooling arrangements.
