Associated Spring Raymond 106-304 Die Spring Extra Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 106-304 is an extra heavy-duty die spring designed for high-load tooling and stamping applications. It features a trapezoidal wire shape and is manufactured from chromium alloy steel for durability under repeated compression cycles. The spring has a 5/8-inch hole diameter, an 11/32-inch rod diameter, and a 1-inch free length. It is rated for a maximum deflection load of 157.5 pounds over a maximum deflection of 0.25 inches, yielding a spring rate of 630 pounds per inch. The green color coding identifies it as an extra heavy-duty rated spring per standard die spring classification conventions. Licensed tooling and die professionals or industrial maintenance technicians are the typical installers.

This die spring is suited for use in punch and die tooling, progressive dies, injection molds, jigs, and fixtures where consistent, high-force return action is required. Its compact 1-inch free length makes it appropriate for applications with limited axial space. The extra heavy-duty rating makes it a fit for high-cycle production tooling environments in both industrial and commercial manufacturing settings.

Key Features

• Extra heavy-duty duty rating for high-load, high-cycle tooling applications
• Trapezoidal wire cross-section provides higher load capacity relative to round wire designs
• Chromium alloy steel construction for fatigue resistance under repeated compression
• Green color coding for quick visual identification of extra heavy-duty rating
• Maximum deflection load of 157.5 pounds at 0.25 inches of travel
• Spring rate of 630 pounds per inch for predictable, consistent force output

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for punch and die assemblies, progressive dies, and industrial tooling that accept a 5/8-inch hole diameter and 11/32-inch rod diameter spring with a 1-inch free length.

Installation Notes

Die springs are typically installed and serviced by toolmakers or industrial maintenance technicians familiar with press tooling. Always de-energize and lock out the press before accessing die components. Ensure the mating rod and bore dimensions match the spring specifications before installation. Do not exceed the rated maximum deflection to avoid premature fatigue or spring failure.
