Associated Spring Raymond 103-506 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-506 is a medium-duty die spring designed for use in stamping dies, punch presses, and similar tooling applications. It features a 1 inch hole diameter, a 1/2 inch rod diameter, and a 1-1/2 inch free length. Constructed from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 262.5 pounds and a spring rate of 373 pounds per inch. The blue color designation identifies its medium-duty rating, making it straightforward to select the correct spring for a given load requirement.

This die spring is suited for installation in metal stamping and forming dies, injection mold tooling, and other industrial press applications where consistent force and controlled deflection are required. It is typically installed and serviced by toolmakers, die setters, and industrial maintenance technicians. The compact free length of 1-1/2 inches allows use in tight die sets where space is limited.

Key Features

• Blue color coding indicates medium-duty load rating for fast, accurate identification
• Trapezoidal wire shape provides higher load capacity relative to round-wire springs of the same envelope size
• Chromium alloy steel construction for durability under repeated cycling
• Maximum deflection of 0.75 inches with a load capacity of 262.5 pounds at full deflection
• Spring rate of 373 pounds per inch for predictable, linear force delivery
• Manufactured under ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland registered quality systems

Compatibility

Designed as a standard-profile medium-duty die spring compatible with tooling bores requiring a 1 inch hole diameter and a 1/2 inch guide rod diameter. Suitable for use wherever ISO-style die springs of this color class and dimensional envelope are specified.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance personnel familiar with press tooling safety procedures. Always de-energize and lock out the press before servicing or replacing die springs. Ensure the guide rod and bore surfaces are clean and free of burrs to prevent uneven loading and premature fatigue. Do not compress the spring beyond its rated maximum deflection of 0.75 inches, as over-compression will shorten service life significantly.
