Associated Spring Raymond 204-708 Die Spring 2 in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-708 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and other high-cycle tooling applications. It features a trapezoidal wire shape that delivers higher load capacity in a compact envelope compared to standard round-wire springs. With a free length of 2 inches (51 mm), a hole diameter of 40 mm, and a rod diameter of 20 mm, this blue-coded spring falls in the heavy-load classification. The chromium alloy steel construction provides the fatigue resistance and consistent spring rate demanded by production tooling environments. Installation and maintenance are typically handled by tool and die makers or mechanical maintenance technicians.

This die spring is suited for use in metal stamping dies, injection mold tooling, and industrial press applications where controlled, repeatable compression force is required. The blue color coding indicates a heavy-load rating, making it appropriate for applications requiring higher force over a defined stroke. It fits into a 40 mm hole and rides on a 20 mm guide rod, which is a common configuration in standard die sets across industrial manufacturing operations.

Key Features

• Trapezoidal wire cross-section provides increased load capacity versus round-wire die springs of the same envelope size
• Blue color code designates heavy-load classification for easy field identification
• 2 inches (51 mm) free length with 19 mm maximum deflection stroke
• Spring rate of 1036.96 N/mm for consistent, predictable force output throughout the compression cycle
• Chromium alloy steel construction for high fatigue life in repetitive-cycle tooling environments
• Manufactured to ISO 10243 standards with ANAB-accredited ISO 9001:2008 and ISO/TS 16949:2009 certifications

Compatibility

Designed for use in standard die sets and tooling assemblies that accept a 40 mm hole diameter and 20 mm rod diameter spring per ISO 10243 dimensional standards.

Installation Notes

Die springs are installed and replaced by tool and die makers or qualified mechanical maintenance personnel. Before servicing any press or die assembly, lock out and tag out all energy sources per OSHA LOTO procedures. Ensure the guide rod and hole bore are within the specified dimensional tolerances to prevent spring binding or premature failure. Never exceed the rated maximum deflection of 19 mm, as compressing a die spring to solid will significantly reduce service life.
