Associated Spring Raymond 105-418 Heavy-duty Die Spring

Product Description

The ASSOCIATED SPRING RAYMOND 105-418 is a heavy-duty die spring designed for use in stamping dies, press tooling, and industrial machinery applications. Built from chromium alloy steel with a trapezoidal wire profile, this spring delivers a maximum load deflection of 297 pounds at a maximum deflection of 1.35 inches. The gold color coding identifies it as a heavy-duty rating per standard die spring classification. With a spring rate of 220 pounds per inch, it provides consistent, predictable resistance across its travel range. Toolmakers, die setters, and industrial maintenance technicians install this part in production tooling and press die assemblies.

This die spring is suited for stamping, forming, and punching die assemblies in both light industrial and heavy manufacturing environments. It fits standard die sets requiring a 0.75-inch hole diameter and a 0.375-inch rod diameter guide post. The 4.5-inch free length accommodates tooling with moderate stroke requirements. It is appropriate for applications demanding repeatable load performance and fatigue resistance over high-cycle operation.

Key Features

• Heavy-duty duty rating with gold color coding for quick identification
• Chromium alloy steel construction for fatigue resistance in high-cycle applications
• Trapezoidal wire cross-section maximizes load capacity within the spring envelope
• 297 pound maximum deflection load at 1.35 inches maximum deflection
• Spring rate of 220 pounds per inch for predictable load progression
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a standard die spring replacement for tooling and press die assemblies requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 4.5-inch free length in a heavy-duty gold-series application.

Installation Notes

Die springs are installed by toolmakers and die maintenance technicians during die set assembly or tooling repair. Always de-energize and lock out the press before accessing die components. Ensure the guide post diameter and die pocket bore match the rod and hole diameter specifications before seating the spring. Do not compress the spring beyond its rated maximum deflection, as over-compression reduces service life and can cause spring failure.
