Associated Spring Raymond 103-520 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-520 is a medium-duty die spring designed for use in stamping dies, presses, and tooling fixtures that require consistent, repeatable compressive force. Built from chromium alloy steel with a trapezoidal wire profile, it delivers a spring rate of 96 pounds per inch and handles a maximum deflection load of 240 pounds over a maximum deflection of 2.5 inches. The blue color coding indicates medium-duty classification, making identification fast during die maintenance. This spring is installed by tool and die makers, press maintenance technicians, and industrial machine mechanics.

This die spring fits applications requiring a 1 inch hole diameter and a 0.5 inch rod diameter, with a free length of 5 inches. It is suited for metal stamping dies, injection mold tooling, punch and die sets, and similar fixture assemblies in production and job-shop environments. The chromium alloy steel construction holds up under repeated cycling in high-load industrial press applications.

Key Features

• Medium-duty blue color classification for quick visual identification during die service
• Trapezoidal wire shape increases load capacity relative to round-wire springs of similar dimensions
• 96 pounds per inch spring rate provides consistent, predictable force output
• 240 pound maximum deflection load with 2.5 inch maximum deflection
• Chromium alloy steel construction for durability under repetitive cycling
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for tooling and fixture assemblies requiring a 1 inch hole diameter, 0.5 inch rod diameter, and 5 inch free length in medium-duty press and stamping applications.

Installation Notes

Die springs should be installed by qualified tool and die technicians or press maintenance personnel. Always de-energize and lock out the press before accessing the die set. Ensure the rod diameter and hole diameter of the spring pocket match the specified 0.5 inch rod and 1 inch hole to prevent buckling or off-axis loading. Do not compress the spring beyond the rated 2.5 inch maximum deflection, as over-compression leads to premature fatigue failure.
