Associated Spring Raymond 103-616 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-616 is a medium-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 352 pounds and a maximum deflection of 2 inches. The spring rate is 176 pounds per inch. Color-coded blue per ISO die spring standards, the 103-616 is straightforward to identify and sort in a multi-spring tooling setup. Installation is handled by tooling technicians, maintenance professionals, and die-setters working in industrial manufacturing environments.

This die spring is suited for medium-duty cycling applications in stamping and forming dies. The 1-1/4 inch hole diameter accepts standard die posts and the 5/8 inch rod diameter is compatible with standard guide rods used in press tooling. The 4 inch free length makes it a common fit for mid-depth die sets. Blue color coding indicates medium-duty rating under ISO and JIS die spring classification conventions.

Key Features

• Chromium alloy steel construction for fatigue resistance under repetitive cycling
• Trapezoidal wire cross-section increases load capacity relative to round wire at the same outside diameter
• Medium-duty rating, color-coded blue per standard die spring classification
• 352 pound maximum deflection load with 2 inch maximum deflection
• 176 pounds per inch spring rate for consistent, predictable force output
• Manufactured under ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland registered quality systems

Compatibility

Designed as a standard medium-duty die spring for use with guide rods of 5/8 inch diameter and die bores of 1-1/4 inch diameter in industrial stamping and forming tooling.

Installation Notes

Die springs must be installed over a guide rod or inside a bore to prevent buckling under load. Always de-energize and lock out the press before servicing tooling components. Do not exceed the rated maximum deflection of 2 inches, as over-compression accelerates fatigue failure. Replacement is typically performed by a die-setter or tooling maintenance technician following the press manufacturer's service procedures.
