Associated Spring Raymond 106-406 Die Spring Extra Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 106-406 is an extra heavy-duty die spring engineered for high-load stamping, forming, and tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 890 pounds per inch and handles a maximum deflection load of 333.8 pounds at 0.38 inches of travel. The green color coding identifies it as an extra heavy-duty rating per international die spring standards. Toolmakers, press operators, and die maintenance technicians install this spring in precision die sets where consistent, repeatable force is required over extended cycle counts.

This spring is suited for metal stamping dies, progressive dies, forming tools, and similar press tooling found in production manufacturing environments. With a 0.75 inch hole diameter and 0.375 inch rod diameter, it mounts on a guide rod and seats in a standard spring pocket machined to match its 0.75 inch outer diameter. The 1.5 inch free length makes it appropriate for applications where compressed working space is limited. Industrial maintenance professionals and tool-and-die technicians are the primary installers in both job shop and high-volume production settings.

Key Features

• Extra heavy-duty rating for high-force stamping and forming tooling
• Trapezoidal wire profile increases load capacity compared to round wire at the same overall dimensions
• Spring rate of 890 pounds per inch for precise, consistent force output
• Maximum deflection load of 333.8 pounds at 0.38 inches travel
• Chromium alloy steel construction for wear resistance and fatigue life in cyclic applications
• Green color coding for quick duty-rating identification per standard die spring conventions
• 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-fit die spring for standard die sets requiring a 0.75 inch hole diameter, 0.375 inch rod diameter, and 1.5 inch free length in an extra heavy-duty green-grade application.

Installation Notes

Die springs are installed by tool-and-die technicians and press maintenance personnel. Always de-energize and lock out the press before removing or replacing die springs. Inspect the guide rod and spring pocket for wear, scoring, or misalignment before installing a replacement spring. Never operate a die spring beyond its rated maximum deflection, as over-compression accelerates fatigue failure and creates a safety hazard.
