Associated Spring Raymond 103-207 Die Spring Blue Medium Duty

Product Description

The ASSOCIATED SPRING RAYMOND 103-207 is a medium-duty die spring designed for use in stamping dies, punch press tooling, and similar industrial forming applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent load characteristics and extended fatigue life under cyclic compression. It has a 0.5 inch hole diameter, a 9/32 inch rod diameter, and a free length of 1.75 inches. Maximum deflection load is 52.5 pounds at 0.88 inches of travel. The blue color designation identifies it as a medium-duty rating within the standard ISO die spring classification system. Toolmakers and machine maintenance technicians are the primary installers.

This spring is suited for light-to-medium force applications in production stamping dies, injection mold lifters, and mechanical assemblies requiring a compact, consistent return force. The 0.5 inch hole diameter and 9/32 inch rod diameter allow straightforward integration into standard die sets and guided spring pockets. Its compact 1.75 inch free length makes it appropriate for applications with limited pocket depth where a full-length heavy-duty spring would not fit.

Key Features

• Medium-duty blue color code per standard ISO die spring classification
• Trapezoidal wire shape for higher load capacity relative to round-wire springs of similar size
• Chromium alloy steel construction for fatigue resistance under repeated cycling
• Spring rate of 60 pounds per inch for predictable, linear load response
• Maximum deflection of 0.88 inches with a peak load of 52.5 pounds
• 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 component for standard die spring pockets requiring a 0.5 inch hole diameter and 9/32 inch rod diameter with a 1.75 inch free length in medium-duty blue classification.

Installation Notes

Installation is typically performed by toolmakers or die maintenance technicians during die assembly or press maintenance. Before servicing any press tooling, de-energize and lock out the press per applicable OSHA lockout/tagout procedures. Ensure the spring pocket and guide rod are clean and free of debris before seating the spring. Do not compress the spring beyond its rated maximum deflection of 0.88 inches, as exceeding this limit will reduce fatigue life and can cause premature failure.
