Associated Spring Raymond 106-520 Die Spring Green

Product Description

The ASSOCIATED SPRING RAYMOND 106-520 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. It features a 1 inch hole diameter, a 1/2 inch rod diameter, and a 5 inch free length. The trapezoidal wire profile delivers a higher load capacity than round-wire springs of comparable size, with a maximum deflection load of 540 pounds and a maximum deflection of 1.25 inches. The spring rate is rated at 432 pounds per inch. Constructed from chromium alloy steel, this green-coded spring indicates a heavy load class per standard die spring color conventions. It is installed by tool and die makers, press operators, and mechanical maintenance technicians in production environments.

The 106-520 is suited for use in stamping dies, mold bases, and mechanical presses where consistent, repeatable spring force is required. The green color coding identifies the heavy load series, making it straightforward to select and replace during die maintenance. With a 1 inch hole diameter and 1/2 inch rod diameter, this spring is sized for common die set configurations found in metal fabrication and manufacturing facilities. It is sold individually with a minimum order quantity of one.

Key Features

• Trapezoidal wire shape provides higher load density than round-wire alternatives
• Maximum deflection load of 540 pounds with a spring rate of 432 pounds per inch
• Maximum deflection of 1.25 inches over a 5 inch free length
• Green color coding identifies heavy load class for quick field identification
• Chromium alloy steel construction for durability under repeated cycling
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a heavy-duty die spring replacement for industrial stamping dies and press tooling requiring a 1 inch hole diameter, 1/2 inch rod diameter, and 5 inch free length in the green heavy load series.

Installation Notes

Die spring replacement is performed by tool and die technicians or press maintenance personnel. Ensure all press tooling is de-energized, ram is blocked, and pneumatic or hydraulic pressure is fully relieved before accessing die components. Verify hole and rod diameter clearances match the replacement spring before installation to prevent binding or misalignment. Do not compress beyond the rated maximum deflection of 1.25 inches to avoid permanent set or premature failure.
