Associated Spring Raymond 104-108 Die Spring Red Medium Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 104-108 is a medium heavy-duty die spring designed for use in stamping dies, punch press tooling, and similar industrial fixture applications. It features a 3/8 inch hole diameter, a 3/16 inch rod diameter, and a 2 inch free length. The trapezoidal wire shape and chromium alloy steel construction provide consistent force characteristics under repeated compression cycles. With a maximum deflection load of 37 pounds and a spring rate of 50 pounds per inch, this unit delivers predictable, repeatable performance in high-cycle tooling environments. The red color coding identifies its medium heavy-duty duty rating per industry convention.

This die spring is suited for use in metal stamping dies, injection mold tooling, and similar precision fixture assemblies found in manufacturing and fabrication shops. Its compact 2 inch free length and small rod diameter make it appropriate for tight-clearance die sets where consistent return force is critical. Toolmakers, die maintenance technicians, and industrial machine shops are the primary installers and end users of this component.

Key Features

• Trapezoidal wire cross-section for higher load capacity relative to round-wire springs of similar envelope size
• Chromium alloy steel construction for fatigue resistance under repetitive cycling
• Red color coding indicates medium heavy-duty duty rating for fast visual identification
• Maximum deflection load of 37 pounds with a spring rate of 50 pounds per inch
• Maximum deflection of 0.74 inches provides a defined working range for die set design
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as a standard-format die spring for use in stamping dies, punch tooling, and industrial fixtures that accept a 3/8 inch hole diameter and 3/16 inch rod diameter spring with a 2 inch free length.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance personnel familiar with press tooling safety procedures. Always de-energize and lock out the press before servicing or replacing die springs. Ensure the spring seat and guide rod are free of burrs or debris that could cause uneven seating or premature wear. Do not compress the spring beyond its rated maximum deflection of 0.74 inches, as exceeding this limit reduces service life significantly.
