Associated Spring Raymond 103-406 Die Spring Medium-duty Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-406 is a medium-duty die spring designed for use in stamping dies, punch presses, and other industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire profile, it delivers a spring rate of 200 pounds per inch and handles a maximum deflection load of 150 pounds. The blue color coding identifies it as a medium-duty spring per standard die spring classifications. Licensed tradespeople and tooling technicians working in metal fabrication and press tooling will find this spring suitable for demanding cycle applications where consistent return force is required.

This spring is suited for industrial tooling setups where controlled compression and reliable return force are critical. The 0.75-inch hole diameter and 0.375-inch rod diameter make it compatible with standard die set guided installations. With a free length of 1.5 inches and a maximum deflection of 0.75 inches, it fits compact tooling cavities common in progressive and compound die assemblies. It is installed by tooling engineers, die makers, and press maintenance technicians in manufacturing and fabrication environments.

Key Features

• Trapezoidal wire cross-section provides higher load capacity relative to round-wire springs of the same envelope size
• Chromium alloy steel construction for durability under high-cycle fatigue conditions
• Blue color coding identifies medium-duty rating for quick visual classification during tooling setup
• Spring rate of 200 pounds per inch for predictable and consistent force output
• Maximum deflection load of 150 pounds with 0.75 inches maximum deflection travel
• 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 standard guided die sets requiring a 0.75-inch hole diameter and 0.375-inch rod diameter with a 1.5-inch free length in medium-duty applications.

Installation Notes

Die springs are installed by qualified tooling technicians and die makers. Always relieve press tonnage and lock out the press ram before servicing or replacing springs in a die set. Inspect the guide pins and bushings for wear before installing a new spring, as misalignment accelerates fatigue failure. Do not exceed the published maximum deflection of 0.75 inches, as over-compression will reduce spring service life.
