Associated Spring Raymond 105-520 Die Spring Heavy-duty Gold

Product Description

The ASSOCIATED SPRING RAYMOND 105-520 is a heavy-duty die spring designed 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 shape allows for higher load capacity within a compact cross-section compared to round-wire springs. With a maximum deflection load of 468 pounds and a maximum deflection of 1.5 inches, this spring delivers consistent, repeatable force output under demanding cycle loads. It is manufactured from chromium alloy steel and color-coded gold to indicate heavy-duty duty rating for fast identification in the shop.

This spring is suited for industrial and manufacturing environments where precision tooling requires reliable spring return force. Typical applications include die sets, mold components, automated press tooling, and fixture clamping systems. The gold color coding follows industry-standard die spring classification, making it straightforward to source replacements and match load requirements during tooling maintenance or build-out. Tooling engineers, die makers, and maintenance machinists are the primary installers and users of this component.

Key Features

• Heavy-duty duty rating with gold color coding for quick load-class identification
• Trapezoidal wire cross-section provides higher load capacity relative to envelope size
• Maximum deflection load of 468 pounds with a spring rate of 312 pounds per inch
• Maximum deflection of 1.5 inches over a 5 inch free length
• Chromium alloy steel construction for fatigue resistance under repeated cycling
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a standard-profile heavy-duty die spring compatible with tooling bores requiring a 1 inch hole diameter and a 1/2 inch guide rod diameter, conforming to common die spring dimensional standards.

Installation Notes

Die springs of this type are installed by tooling technicians and die makers during die assembly or maintenance. Before servicing any press tooling, de-energize and lock out the press in accordance with applicable OSHA lockout/tagout procedures. Ensure the guide rod diameter and bore dimensions match the spring specifications before installation to prevent buckling or misalignment under load. Never compress the spring beyond its rated maximum deflection, as over-compression can cause permanent set or premature fatigue failure.
