Associated Spring Raymond 103-524 Die Spring Blue Medium-duty

Product Description

The ASSOCIATED SPRING RAYMOND 103-524 is a medium-duty die spring engineered for use in stamping dies, press tooling, and industrial machinery applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a spring rate of 80 pounds per inch and handles a maximum deflection load of 240 pounds over 3 inches of travel. The blue color coding indicates medium-duty load classification per ISO die spring standards. It is installed and serviced by tooling technicians, die setters, and maintenance machinists working in metal fabrication and press environments.

This die spring is suited for use in progressive dies, compound dies, and stripper plate assemblies where controlled force and repeatable deflection are required. With a 1-inch hole diameter and 0.5-inch rod diameter, it fits standard die spring pockets and guide rods common in medium-duty press tooling. The 6-inch free length provides adequate working travel for typical stripper and pressure pad applications in both light manufacturing and production stamping environments.

Key Features

• Chromium alloy steel construction for high fatigue resistance in cyclic loading applications
• Trapezoidal wire profile increases load capacity relative to round wire at equivalent outside diameter
• Blue color code identifies medium-duty load rating for quick visual identification during die setup
• 80 pounds per inch spring rate provides predictable, linear force output through the deflection range
• Maximum deflection load of 240 pounds at 3 inches of travel suits standard stripper and pad assemblies
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality management systems

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for medium-duty stamping die assemblies using standard 1-inch bore pockets and 0.5-inch guide rods.

Installation Notes

Die springs are installed by qualified toolmakers or die setters with the press fully de-energized and all stored energy released from the tooling. Inspect the spring pocket and guide rod for wear or scoring before installation, as surface damage accelerates spring fatigue. Never compress a die spring beyond its rated maximum deflection, as over-compression causes permanent set and premature failure. Follow applicable shop safety procedures and equipment lockout/tagout protocols before accessing any press tooling.
