Associated Spring Raymond 103-548 Die Spring Medium-duty Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-548 is a medium-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a 1 inch hole diameter, a 0.5 inch rod diameter, and a 12 inch free length, making it suited for applications requiring consistent force over a long stroke. The spring is manufactured from chromium alloy steel with a trapezoidal wire cross-section, which provides a higher load capacity relative to round wire springs of the same envelope size. A maximum deflection load of 240 pounds and a maximum deflection of 6 inches define its working range. Licensed HVAC techs, toolmakers, and die maintenance technicians are the primary installers of this component.

This die spring is applied in metal stamping, forming, and punching tooling where reliable spring-back force is required. The blue color coding indicates a medium-duty rating under the ISO die spring classification system, making it identifiable at a glance during tool setup or maintenance. It is appropriate for both original equipment installation and replacement in existing die sets that specify a medium-duty spring with a 1 inch outer diameter envelope. The 12 inch free length suits deep-draw die applications or situations where extended travel and consistent spring rate are required throughout the stroke.

Key Features

• Trapezoidal wire cross-section delivers higher load density than round wire springs in the same footprint
• Chromium alloy steel construction provides strength and fatigue resistance under cyclic loading
• Blue color coding indicates medium-duty rating for quick visual identification
• 40 pounds per inch spring rate supports predictable, linear force output
• Maximum deflection of 6 inches with a maximum load of 240 pounds at full deflection
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or new-installation die spring for stamping and forming dies requiring a medium-duty spring with a 1 inch hole diameter, 0.5 inch rod diameter, and 12 inch free length.

Installation Notes

Die springs are typically installed and replaced by toolmakers or die maintenance technicians. Always relieve all press and tooling load before removing or replacing a die spring. Inspect the rod and bore mating surfaces for wear or damage before installing a new spring, as misalignment accelerates fatigue failure. Do not compress the spring beyond its rated maximum deflection of 6 inches during installation or operation.
