Associated Spring Raymond 104-210 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-210 is a medium heavy-duty die spring designed for use in stamping dies, punch presses, and tooling fixtures where consistent force and reliable deflection are required. Built from chromium alloy steel with a trapezoidal wire shape, it delivers a spring rate of 60.00 pounds per inch and a maximum deflection load of 55.5 pounds over a maximum deflection of 0.93 inches. The red color coding follows the ISO standard for medium heavy-duty die springs, making identification quick during die setup and maintenance. Toolmakers, die setters, and press room technicians are the primary installers of this component.

This die spring is suited for medium heavy-duty tooling applications in metal stamping, forming, and machining operations. It fits a 0.5 inch hole diameter and accepts a 0.28125 inch rod diameter, with a free length of 2.5 inches. Typical installation environments include progressive dies, compound dies, and standard die sets used in both production and job shop settings where repeatable spring performance is critical to part quality and die longevity.

Key Features

• Medium heavy-duty duty rating with red color coding for easy identification
• Trapezoidal wire shape provides higher load capacity versus round wire at equivalent free length
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• Spring rate of 60.00 pounds per inch with maximum deflection load of 55.5 pounds
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems
• ANAB Accredited and TUV Rheinland Registered for compliance-sensitive applications

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for medium heavy-duty tooling applications requiring a 0.5 inch hole diameter, 0.28125 inch rod diameter, and 2.5 inch free length.

Installation Notes

Die springs of this type are installed by toolmakers or die maintenance technicians during die build or rebuild operations. Always relieve all stored mechanical energy and confirm the press is locked out before removing or replacing die springs. Do not compress the spring beyond its rated maximum deflection of 0.93 inches, as over-compression accelerates fatigue failure. Verify rod and hole clearances before installation to prevent binding and uneven load distribution.
