Associated Spring Raymond 104-307 Die Spring Red Medium Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 104-307 is a medium heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a 0.625-inch hole diameter, an 11/32-inch rod diameter, and a free length of 1.75 inches. Constructed from chromium alloy steel with a trapezoidal wire shape, this spring delivers a maximum deflection load of 108.8 pounds and a maximum deflection of 0.65 inches. The red color coding follows standard die spring duty-rating conventions, making identification fast during tool changes and maintenance. Licensed HVAC, plumbing, and mechanical tradespeople as well as tool and die professionals install and service this component.

This die spring is suited for compression applications in industrial press tooling, injection mold assemblies, and mechanical fixture components requiring consistent, repeatable force output. The medium heavy-duty duty rating positions it between light-duty and extra heavy-duty options, making it a common selection for moderate-load cycling applications. Its compact 1.75-inch free length fits space-constrained tooling cavities. With a spring rate of 168.00 pounds per inch, it provides predictable load-deflection behavior across its working range.

Key Features

• Trapezoidal wire shape maximizes load capacity relative to coil space
• Red color coding identifies medium heavy-duty rating at a glance
• Maximum deflection load of 108.8 pounds with 0.65 inches maximum deflection
• Spring rate of 168.00 pounds per inch for consistent, predictable performance
• Manufactured under ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland registered quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial die and punch press tooling requiring a 0.625-inch hole diameter, 11/32-inch rod diameter, and 1.75-inch free length compression spring in the medium heavy-duty red duty-rating class.

Installation Notes

Installation is typically performed by tool and die technicians or mechanical maintenance trades. Before replacing or servicing die springs, fully relieve all press or clamp pressure and lock out the press ram per applicable machine-guarding and OSHA lockout/tagout procedures. Inspect the mating rod and bore for wear or misalignment that could cause side loading, which shortens spring life. Never compress a die spring beyond its rated maximum deflection.
