Associated Spring Raymond 105-840 Die Spring Gold

Product Description

The ASSOCIATED SPRING RAYMOND 105-840 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, a 1-inch rod diameter, and a free length of 10 inches. The trapezoidal wire profile provides a higher load-carrying capacity per coil compared to standard round wire, making it well suited for high-cycle tooling environments. At maximum deflection of 3 inches, the spring delivers a peak load of 1,650 pounds. Manufactured from chromium alloy steel, it is color-coded gold to indicate its heavy load class. Installation and replacement are typically handled by tool-and-die technicians and industrial maintenance personnel.

This die spring is designed for use in industrial stamping, forming, and metal fabrication tooling. The gold color coding corresponds to the heavy load class within standard die spring classification systems, which simplifies selection and replacement in production tooling. With a spring rate of 572 pounds per inch, it provides consistent, predictable force across the deflection range. It is appropriate for high-cycle applications where reliable spring force is critical to part quality and tooling longevity.

Key Features

• 2-inch hole diameter and 1-inch rod diameter for direct drop-in replacement in standard die spring pockets
• 10-inch free length with 3-inch maximum deflection for ample travel in deep tooling setups
• 1,650-pound maximum deflection load for heavy-duty press applications
• Spring rate of 572 pounds per inch for predictable, consistent force output
• Trapezoidal wire cross-section delivers higher load density than round wire springs of the same size
• Chromium alloy steel construction with gold color coding for easy heavy-load class identification

Compatibility

Designed as a heavy-load class die spring for use in standard industrial stamping dies, punch presses, and forming tooling that accept a 2-inch hole diameter and 1-inch rod diameter spring pocket configuration.

Installation Notes

Die springs should be installed by qualified tool-and-die technicians or industrial maintenance personnel with the press fully de-energized and locked out per applicable LOTO procedures. Never exceed the rated maximum deflection of 3 inches, as over-compression will shorten service life and can cause spring failure. Inspect the spring seat, pocket bore, and guide rod for wear or damage before installation. Periodic inspection for set, cracking, or corrosion is recommended, especially in high-cycle applications.
