Associated Spring Raymond 103-410 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-410 is a medium-duty die spring engineered for use in stamping dies, punch presses, and similar tooling applications. It features a trapezoidal wire cross-section that delivers higher load capacity in a compact envelope compared to round-wire springs. With a hole diameter of 0.75 inches, a rod diameter of 0.375 inches, and a free length of 2.5 inches, it accepts standard guide rods and fits common die set bores. The spring rate is 120 pounds per inch, with a maximum deflection load of 150 pounds at 1.25 inches of travel. It is manufactured from chromium alloy steel and color-coded blue to indicate medium-duty load class for fast identification during tooling setup and maintenance.

This die spring is suited for production tooling environments in metal stamping, forming, and stripping operations. It is a direct-fit component for die sets requiring a 0.75-inch bore and 0.375-inch rod guide. Toolmakers, die setters, and maintenance technicians install this spring during initial die builds and scheduled tooling rebuilds. The blue color code aligns with the ISO and industry-standard medium-duty designation, making it straightforward to spec as a replacement in existing die assemblies.

Key Features

• Trapezoidal wire profile provides higher load density than comparable round-wire die springs
• 120 pounds per inch spring rate with 150-pound maximum deflection load
• 1.25 inches maximum deflection travel within the 2.5-inch free length
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• Blue color coding identifies medium-duty load class at a glance
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement die spring for tooling applications requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 2.5-inch free length in the medium-duty load class.

Installation Notes

Die springs are installed by toolmakers or die maintenance technicians during die builds or scheduled rebuilds. Always de-energize and lock out the press before accessing the die set. Inspect the guide rod and bore for wear or damage before installing a new spring, as a worn rod can cause uneven loading and premature spring fatigue. Never compress the spring beyond its rated maximum deflection of 1.25 inches during setup or operation.
