Associated Spring Raymond 103-748 Die Spring 12 Inch Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-748 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 12 inch free length. The trapezoidal wire shape provides higher load capacity in a compact cross-section compared to standard round-wire springs. With a maximum deflection load of 480 pounds and a spring rate of 85 pounds per inch, this blue-coded spring falls in the heavy-load classification. Fabricated from chromium alloy steel for durability under repeated high-cycle compression. Suitable for licensed toolmakers, die setters, and maintenance technicians working on industrial press equipment.

This die spring is designed for industrial press tooling environments where consistent, repeatable force is required across high-cycle operations. The blue color coding indicates heavy load capacity per standard die spring classification systems. Typical applications include metal stamping dies, injection mold components, and mechanical press tooling where controlled compression and return force are critical. With a 6 inch maximum deflection and a 12 inch free length, it suits moderate to deep tool travel requirements. Sold individually.

Key Features

• 1-1/2 inch hole diameter and 3/4 inch rod diameter for straightforward die plate mounting
• 12 inch free length accommodates moderate to deep press travel setups
• 480 pound maximum deflection load with a spring rate of 85 pounds per inch
• 6 inch maximum deflection for high-cycle compression applications
• Trapezoidal wire cross-section increases load density versus round-wire alternatives
• Chromium alloy steel construction resists fatigue and wear under sustained cyclic loading
• Blue color coding denotes heavy load classification per industry convention

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for industrial stamping dies, punch press tooling, and mechanical press assemblies requiring a 1-1/2 inch hole diameter, 3/4 inch rod diameter, and 12 inch free length heavy-load spring.

Installation Notes

Installation is performed by qualified toolmakers or die maintenance technicians. Always depressurize and lock out the press before replacing die springs. Verify that the mating die plate bore and guide rod dimensions match the spring specifications before installation. Do not exceed the rated maximum deflection of 6 inches, as operating beyond the rated travel will accelerate fatigue failure and reduce service life.
