Associated Spring Raymond 103-516 Die Spring Blue Medium-duty

Product Description

The ASSOCIATED SPRING RAYMOND 103-516 is a medium-duty die spring designed for use in stamping dies, punch presses, and tooling fixtures where controlled compression force is required. It features a 1-inch hole diameter, a 1/2-inch rod diameter, and a 4-inch free length, with a trapezoidal wire cross-section that delivers consistent load distribution throughout the compression cycle. Manufactured from chromium alloy steel, this spring carries a maximum deflection load of 240 pounds and a maximum deflection of 2 inches, making it well suited for repetitive, high-cycle tooling applications. Industrial maintenance technicians and tool-and-die professionals are the primary installers.

This spring is intended for use in precision die and tooling applications across light manufacturing, metal fabrication, and production stamping environments. The blue color designation indicates medium-duty load rating under the ISO die spring color-coding standard. It is appropriate for applications requiring a spring rate of 125 pounds per inch and installations where the rod diameter is 1/2 inch and the bore is 1 inch. This part is sold individually.

Key Features

• Trapezoidal wire cross-section for higher load capacity relative to round-wire springs of the same envelope size
• 1-inch hole diameter and 1/2-inch rod diameter for precise fitment in standard die sets
• 240-pound maximum deflection load with a spring rate of 125 pounds per inch
• 2-inch maximum deflection over a 4-inch free length
• Chromium alloy steel construction for durability in high-cycle tooling environments
• Meets ISO 9001:2008 and ISO/TS 16949:2009 quality standards; TUV Rheinland Registered and ANAB Accredited

Compatibility

Designed as a standard medium-duty die spring suitable for tooling fixtures, stamping dies, and punch press assemblies that accept a 1-inch bore and 1/2-inch guide rod with a 4-inch free length envelope.

Installation Notes

Die springs are installed by tool-and-die technicians and industrial maintenance personnel. Always de-energize and lockout the press or machine before servicing any tooling components. Ensure the guide rod and bore dimensions match the spring specifications before installation, and never compress the spring beyond its rated maximum deflection of 2 inches to avoid permanent set or fatigue failure.
