Associated Spring Raymond 103-307 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-307 is a medium-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire profile, it delivers consistent force over repeated compression cycles. The spring features a 0.625-inch hole diameter, an 11/32-inch rod diameter, and a free length of 1.75 inches. It handles a maximum deflection load of 84 pounds across 0.88 inches of travel, with a spring rate of 96 pounds per inch. The blue color coding indicates medium-duty classification per standard die spring conventions, making identification fast during tool setup and maintenance.

This die spring is suited for use in metal stamping, forming, and die-set applications in both production and job-shop environments. It fits rod-guided or hole-guided configurations within tooling assemblies. Industrial maintenance technicians and tooling engineers typically select this spring for medium-load stripper plates, blank holders, and similar die components where precise force control and compact dimensions are required.

Key Features

• Chromium alloy steel construction for high fatigue resistance under cyclic loading
• Trapezoidal wire cross-section increases load capacity relative to round-wire springs of the same envelope
• 84-pound maximum deflection load with 0.88 inches of maximum travel
• Spring rate of 96 pounds per inch for predictable, linear force delivery
• Blue color coding denotes medium-duty rating for quick visual identification
• Manufactured under ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland registered quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for medium-duty stamping die and punch press tooling assemblies requiring a 0.625-inch hole diameter, 11/32-inch rod diameter, and 1.75-inch free length.

Installation Notes

Installation is performed by tooling engineers or die maintenance technicians during die build or spring replacement. Always de-energize and lock out the press before servicing die components. Ensure the rod and hole dimensions in the die set match the spring specifications to prevent buckling or misalignment under load. Do not compress the spring beyond its rated maximum deflection of 0.88 inches during operation or setup.
