Associated Spring Raymond 104-548 Die Spring Red 12 in

Product Description

The Associated Spring Raymond 104-548 is a red-coded die spring designed for use in stamping dies, punch presses, and other high-cycle tooling applications. It features a 1 inch hole diameter, a 1/2 inch rod diameter, and a 12 inch free length. The trapezoidal wire shape provides a higher load capacity in a compact cross-section compared to round-wire springs. With a spring rate of 65 pounds per inch and a maximum deflection load of 275.3 pounds at 4.44 inches of travel, this spring is suited for medium-load die applications. Installation is performed by toolmakers, die setters, and maintenance machinists.

This die spring fits standard die sets where a 1 inch bore and 1/2 inch guide rod are used. The red color coding indicates a medium load class per common industry die spring standards, making it straightforward to identify and replace in multi-spring die configurations. It is appropriate for use in metal stamping, forming, and stripping operations in both production and job-shop environments. Chromium alloy steel construction provides the fatigue resistance required for repetitive compression cycles.

Key Features

• Trapezoidal wire cross-section delivers higher load capacity per unit of compressed length versus round wire
• Red color coding denotes medium load class for fast visual identification during die maintenance
• Chromium alloy steel construction for high fatigue life under repetitive cycling
• Spring rate of 65 pounds per inch provides predictable, linear load response
• Maximum deflection load of 275.3 pounds at 4.44 inches of travel
• 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 1 inch hole diameter, 1/2 inch rod diameter, and 12 inch free length in the red medium-load class.

Installation Notes

Die springs are installed and replaced by toolmakers or die maintenance technicians. Before servicing a die set, ensure the press is fully de-energized, locked out, and the slide is blocked per OSHA lockout/tagout procedures. Install the spring over the guide rod and confirm the spring seats squarely in the pocket without lateral preload. Do not compress the spring beyond the rated maximum deflection of 4.44 inches during setup or operation.
