Associated Spring Raymond 103-620 Die Spring Blue Medium-duty

Product Description

The ASSOCIATED SPRING RAYMOND 103-620 is a medium-duty die spring engineered for use in stamping dies, punch presses, and other tooling applications where consistent, reliable spring force is required. It features a 1-1/4 inch hole diameter, a 5/8 inch rod diameter, and a 5 inch free length. The trapezoidal wire shape provides a higher load capacity relative to its space envelope compared to round-wire springs. Rated at a maximum deflection load of 340 pounds and a maximum deflection of 2.5 inches, this spring is well-suited for repetitive cycling in production tooling environments. It is installed by toolmakers, die setters, and industrial maintenance technicians.

This die spring is designed for use in compression applications within metal stamping dies, injection mold tooling, and general industrial machinery. The blue color coding indicates a medium-duty load rating, following the industry-standard color identification system used across interchangeable die spring families. It is suitable for applications that require a spring rate of 143 pounds per inch and a controlled, repeatable return stroke in high-cycle tooling setups.

Key Features

• 1-1/4 inch hole diameter and 5/8 inch rod diameter for standard die pocket fitment
• 5 inch free length with 2.5 inch maximum deflection (50 percent deflection ratio)
• Maximum deflection load of 340 pounds at full deflection
• Spring rate of 143 pounds per inch for predictable force progression
• Trapezoidal wire cross-section maximizes load capacity within a compact envelope
• Chromium alloy steel construction for durability in high-cycle applications
• Blue color coding per medium-duty industry classification standard

Compatibility

Designed as an OEM-style replacement or direct interchange for medium-duty blue die springs with a 1-1/4 inch hole diameter, 5/8 inch rod diameter, and 5 inch free length in standard die spring pocket configurations.

Installation Notes

Die springs are installed by qualified toolmakers or die setters during die assembly or maintenance. De-energize and lock out all press equipment before removing or replacing die springs. Do not exceed the rated maximum deflection, as over-compression will shorten spring service life and may cause premature failure. Inspect the spring seat and rod for wear or misalignment before installation to ensure proper seating and coaxial loading.
