Associated Spring Raymond 104-732 Die Spring 8in Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-732 is a heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and an 8 inch free length, making it suitable for moderate-to-large die sets that require consistent, high-cycle compression force. Constructed from chromium alloy steel with a trapezoidal wire shape, this spring delivers a maximum load deflection of 651.2 pounds and a maximum deflection of 2.96 inches. The red color coding indicates a heavy-duty load rating per standard die spring classification. Toolmakers, die setters, and maintenance machinists are the primary installers of this component.

This die spring is used in industrial manufacturing environments, primarily in metal stamping, forming, and punching operations. It fits inside standard die sets where the bore accepts a 1-1/2 inch outer diameter spring riding on a 3/4 inch guide rod. The 8 inch free length accommodates applications requiring longer travel or higher preload. Typical installation scenarios include stripper plate assemblies, pressure pads, and knockout mechanisms in progressive and compound dies. This spring is well suited for high-cycle production tooling where consistent spring rate and fatigue resistance are critical.

Key Features

• 1-1/2 inch hole diameter and 3/4 inch rod diameter for standard die set fitment
• 8 inch free length supports longer stroke and higher preload applications
• 651.2 pound maximum deflection load for heavy-duty cycling
• 2.96 inch maximum deflection with a 220 lb/inch spring rate for predictable force output
• Chromium alloy steel construction with trapezoidal wire profile for extended fatigue life
• Red color code denotes heavy-duty load classification per industry standard die spring convention
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for industrial stamping and forming dies that accept a 1-1/2 inch outer diameter spring on a 3/4 inch guide rod with an 8 inch free length clearance.

Installation Notes

Installation is performed by toolmakers or die maintenance technicians. The die set and press must be fully de-energized and locked out before spring replacement. Ensure the guide rod diameter and pocket bore match the rod and hole dimensions of this spring before installation. Do not compress the spring beyond its rated maximum deflection of 2.96 inches, as exceeding this limit will accelerate fatigue failure.
