Associated Spring Raymond 103-218 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-218 is a heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a trapezoidal wire cross-section that delivers higher load capacity in a compact envelope compared to round-wire designs. The spring has a 0.5 inch hole diameter, a 4.5 inch free length, and a maximum deflection load of 56.3 pounds at 2.25 inches of travel. The blue color coding indicates a light load class per standard die spring classification. Manufactured from chromium alloy steel for durability under repeated cycling. Installation and maintenance are typically performed by tool and die technicians or industrial maintenance personnel.

This die spring is suited for light-load tooling applications in stamping and forming operations. The blue load class is commonly specified for applications requiring consistent return force without excessive preload. It fits standard die sets and spring pockets with a 0.5 inch bore, making it a direct drop-in for presses and progressive dies calling for this hole diameter and free length combination. Suitable for both production tooling and prototype fixtures where repeatable spring force is critical.

Key Features

• Trapezoidal wire cross-section provides higher load density than round-wire equivalents
• Blue light-load color classification per standard die spring grading
• 56.3 lb maximum deflection load at 2.25 inches maximum deflection
• Spring rate of 23.0 lb per inch for predictable, linear force output
• Chromium alloy steel construction for fatigue resistance under high-cycle conditions
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or new-installation die spring for standard tooling applications requiring a 0.5 inch hole diameter, 9/32 inch rod diameter, and 4.5 inch free length in the blue light-load class.

Installation Notes

Die springs are installed and replaced by tool and die technicians or qualified industrial maintenance personnel. Always relieve all press and tooling pressure before removing or installing springs. Inspect the spring pocket bore and rod for wear or damage before seating the new spring. Do not exceed the rated maximum deflection of 2.25 inches, as over-compression will accelerate fatigue failure and reduce service life.
