Associated Spring Raymond 104-416 Die Spring Red Medium Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 104-416 is a medium heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a 3/4-inch hole diameter, a 3/8-inch rod diameter, and a 4-inch free length, making it a standard-size compression spring for guided spring applications. The trapezoidal wire shape delivers a higher load capacity relative to wire cross-section compared to round wire springs of the same envelope. With a maximum deflection load of 177.6 pounds and a maximum deflection of 1.48 inches, this spring is built for repeatable, high-cycle performance in demanding press tooling environments. Machinists, tool-and-die makers, and maintenance technicians are the primary installers.

This die spring is suited for use in metal stamping dies, injection mold assemblies, stripper plates, and other guided compression spring applications found in manufacturing and production tooling. The red color coding indicates medium heavy-duty duty rating per industry-standard die spring classification, allowing quick visual identification during die maintenance and changeover. It is appropriate for both OEM tooling builds and MRO replacement service in production environments.

Key Features

• Medium heavy-duty duty rating with red color coding for quick visual identification
• Trapezoidal wire cross-section provides higher load density within a compact envelope
• 3/4-inch hole diameter and 3/8-inch rod diameter for standard guided spring fitment
• Maximum deflection load of 177.6 pounds with a spring rate of 110 pounds per inch
• Maximum deflection of 1.48 inches over a 4-inch free length
• Chromium alloy steel construction for durability in high-cycle press tooling

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for guided compression spring positions in stamping dies, punch presses, and mold assemblies requiring a 3/4-inch hole diameter, 3/8-inch rod diameter, and 4-inch free length with medium heavy-duty loading.

Installation Notes

Die spring installation and replacement is typically performed by tool-and-die makers or maintenance technicians during scheduled die maintenance or after spring fatigue failure. Always de-energize and lockout the press before accessing the die set. Never compress this spring beyond its rated maximum deflection of 1.48 inches, as over-compression accelerates fatigue and can cause premature failure. Inspect the mating hole bore and guide rod for wear or misalignment before installing a replacement spring.
