Associated Spring Raymond 105-718 Heavy-duty Die Spring

Product Description

The ASSOCIATED SPRING RAYMOND 105-718 is a heavy-duty die spring engineered for high-load tooling and stamping applications. It features a trapezoidal wire cross-section that increases load-bearing surface area compared to round wire designs, resulting in higher spring rates in a compact envelope. The 105-718 has a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a free length of 4-1/2 inches. It is manufactured from chromium alloy steel and carries a gold color designation indicating its heavy-duty duty rating per industry standard die spring classifications. Licensed machinists, tool-and-die makers, and press maintenance technicians are the primary installers.

This spring is used in metal stamping dies, punch presses, injection molds, and other industrial tooling assemblies where consistent, high-cycle compression force is required. The gold color code identifies it as a heavy-duty spring, suited for applications demanding higher load capacity within a given size envelope. It is appropriate for both new tooling builds and replacement service on existing die sets where the original spring has fatigued or failed.

Key Features

• Heavy-duty duty rating with gold color designation for straightforward field identification
• Trapezoidal wire shape delivers higher load capacity and longer fatigue life versus round wire springs of equal size
• Maximum deflection load of 1058.4 pounds at 1.35 inches maximum deflection
• Spring rate of 816 pounds per inch for predictable, repeatable force output
• Chromium alloy steel construction for wear resistance and high-cycle durability
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as a standard-profile heavy-duty die spring for use in tooling and stamping assemblies requiring a 1-1/2 inch hole diameter, 3/4 inch rod diameter, and 4-1/2 inch free length.

Installation Notes

Die spring replacement is performed by qualified tool-and-die or press maintenance personnel. Always de-energize and lock out the press or tooling assembly before removing or installing springs. Inspect the mating rod and bore for wear, scoring, or misalignment before installing the new spring, as surface damage accelerates fatigue. Do not compress the spring beyond its rated maximum deflection of 1.35 inches during installation or operation.
