Associated Spring Raymond 103-304 Die Spring Medium-duty Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-304 is a medium-duty die spring engineered for use in stamping dies, punch presses, and similar tooling applications. Built from chromium alloy steel with a trapezoidal wire profile, this spring delivers a maximum load of 82 pounds at full deflection and a spring rate of 164 pounds per inch. The blue color coding identifies its medium-duty rating per industry convention, allowing fast visual identification during tooling setup and maintenance. Licensed toolmakers, die setters, and maintenance machinists are the primary installers of this component.

This die spring is suited for both production stamping dies and custom tooling fixtures in industrial and manufacturing environments. With a 0.625-inch hole diameter and 0.344-inch rod diameter, it mounts to standard die posts and guide rods found in a wide range of press tooling setups. Its 1-inch free length and 0.5-inch maximum deflection make it appropriate for compact die sections requiring consistent return force without excessive travel.

Key Features

• Chromium alloy steel construction for high fatigue resistance under cyclic loading
• Trapezoidal wire cross-section maximizes energy storage within a compact envelope
• Blue color coding indicates medium-duty rating for quick visual identification
• 82-pound maximum deflection load with a 164-pound-per-inch spring rate
• 0.5-inch maximum deflection with a 1-inch free length for precise stroke control
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a standard-profile medium-duty die spring for use with die posts and guide rods accepting a 0.625-inch hole diameter and 0.344-inch rod diameter in industrial stamping and punch press tooling.

Installation Notes

Die spring replacement is typically performed by a qualified toolmaker or die maintenance technician. Always de-energize and lock out the press before accessing the die set. Confirm that the rod diameter and hole diameter of the new spring match the existing tooling post dimensions before seating the spring. Do not compress beyond the rated maximum deflection of 0.5 inches to avoid permanent set or premature failure.
