Associated Spring Raymond 104-104 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-104 is a medium heavy-duty die spring designed for use in stamping dies, punch press tooling, and similar industrial applications requiring reliable cyclic compression force. It features a trapezoidal wire shape that provides greater load capacity relative to its physical size compared to round-wire springs. The spring has a 0.375-inch hole diameter, a 0.1875-inch rod diameter, and a 1-inch free length, making it a compact solution for tight die spaces. Maximum load at full deflection is 33.3 pounds with a spring rate of 84 pounds per inch. The red color coding indicates a medium heavy-duty duty rating per industry convention. Licensed machinists, toolmakers, and die maintenance technicians are the typical installers.

This die spring is suited for use in metal stamping dies, injection mold ejector assemblies, jigs, fixtures, and other precision tooling applications where consistent spring force and long cycle life are required. Its compact 1-inch free length fits shallow die pockets. It is appropriate for both OEM tooling builds and die maintenance replacements in job shops and production stamping operations.

Key Features

• Trapezoidal wire cross-section delivers higher load capacity in a compact envelope compared to standard round-wire die springs
• Medium heavy-duty rating with a spring rate of 84 pounds per inch
• Maximum deflection load of 33.3 pounds at 0.37 inches of travel
• Red color coding for fast duty-rating identification during die maintenance
• Chromium alloy steel construction for durability under repeated compression cycles
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as an OEM-style replacement or direct tooling component for applications requiring a 0.375-inch hole diameter, 0.1875-inch rod diameter, medium heavy-duty die spring with a 1-inch free length. Verify hole diameter, rod diameter, and free length against existing tooling before installation.

Installation Notes

Die springs are installed by toolmakers or die maintenance technicians during die builds or scheduled press maintenance. Always de-energize and lock out the press before servicing any die components. Ensure the mounting pocket depth and rod clearance match the spring dimensions to prevent buckling or coil binding at full deflection. Do not compress the spring beyond its rated maximum deflection of 0.37 inches.
