Associated Spring Raymond 103-818 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-818 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. It features a 2-inch hole diameter and a 1-inch rod diameter, with a free length of 4.5 inches. The trapezoidal wire profile delivers a high spring rate of 530 pounds per inch, allowing the spring to handle a maximum deflection load of 1,192.5 pounds over a maximum deflection of 2.25 inches. Constructed from chromium alloy steel, this blue-coded spring meets the high-load classification standards used throughout the die and mold industry. Machinists, toolmakers, and die maintenance technicians are the typical installers.

This die spring is suited for use in metal stamping dies, injection mold tooling, and heavy-duty industrial press fixtures where consistent, high-load return force is required. The blue color coding identifies it as a heavy-load spring in the standard color-classification system used across die spring product lines. It is appropriate for both OEM tooling builds and maintenance replacement cycles in production environments where repeated compression cycles demand reliable performance.

Key Features

• Trapezoidal wire cross-section for higher load capacity relative to round-wire springs of the same envelope size
• 2-inch hole diameter and 1-inch rod diameter for straightforward die set installation
• 530 pounds per inch spring rate suitable for heavy-load tooling applications
• Maximum deflection load of 1,192.5 pounds at 2.25 inches of deflection
• Chromium alloy steel construction for durability under repeated compression cycling
• Blue color coding identifies heavy-load classification for quick field identification

Compatibility

Designed as an OEM-style replacement or new-build component for heavy-load die spring applications requiring a 2-inch hole diameter, 1-inch rod diameter, and 4.5-inch free length in standard die set configurations.

Installation Notes

Die springs of this type are installed and serviced by toolmakers, die maintenance technicians, and industrial press operators. Always de-energize and lock out the press before servicing a die set. Confirm that the rod diameter and hole diameter of the die set pocket match the spring dimensions before installation. Never compress a die spring beyond its rated maximum deflection, as over-compression will shorten service life and may cause spring failure.
