Associated Spring Raymond 103-420 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-420 is a medium-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a trapezoidal wire shape and is manufactured from chromium alloy steel for consistent load performance and fatigue resistance under repeated cycling. The spring has a 3/4 inch hole diameter, a 3/8 inch rod diameter, and a free length of 5 inches. It delivers a maximum deflection load of 150 pounds at a maximum deflection of 2.5 inches, with a spring rate of 60 pounds per inch. Installation and replacement are handled by toolmakers, die setters, and maintenance technicians.

This spring is suited for medium-duty press tooling and industrial die applications where controlled, repeatable spring force is required. The blue color coding identifies it as a medium-duty rating per standard die spring classification conventions. With a 5 inch free length and a 3/8 inch rod diameter, it fits standard die set configurations calling for those bore and rod dimensions. Typical applications include stripper plates, pressure pads, and component return mechanisms within stamping and forming dies.

Key Features

• Trapezoidal wire cross-section for higher load capacity per unit length compared to round wire
• Chromium alloy steel construction for durability and resistance to fatigue under cyclic loading
• 150 pound maximum deflection load with a 2.5 inch maximum deflection travel
• Spring rate of 60 pounds per inch for predictable, linear force output
• Blue color coding denotes medium-duty rating per standard die spring classification
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for standard tooling applications requiring a 3/4 inch hole diameter, 3/8 inch rod diameter, and 5 inch free length in medium-duty press and stamping die configurations.

Installation Notes

Die springs are installed and serviced by qualified toolmakers or maintenance technicians. Power down and lock out all press equipment per OSHA lockout/tagout procedures before removing or installing springs. Inspect the mating rod and bore for wear or misalignment prior to installation, as side loading will reduce spring service life. Never compress a die spring beyond its rated maximum deflection of 2.5 inches.
