Associated Spring Raymond 103-828 Die Spring 2in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-828 is a heavy-duty die spring engineered for use in stamping dies, presses, and industrial tooling applications where consistent, high-force return action is required. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum load deflection of 1,092 pounds and a spring rate of 312 pounds per inch. The blue color coding identifies it as a heavy-load class spring per standard die spring conventions. At 7 inches free length with a 2-inch hole diameter and 1-inch rod diameter, it fits standard die sets and guide rod assemblies used by toolmakers and maintenance professionals in manufacturing environments.

This die spring is suited for industrial press and stamping die applications where reliable cyclic compression performance is critical. The trapezoidal wire form maximizes material cross-section within the spring envelope, supporting higher load capacity relative to round-wire alternatives of the same envelope size. Typical installations include punch press dies, injection mold return systems, and fixture clamps requiring repeatable force characteristics across high-cycle service life.

Key Features

• Chromium alloy steel construction for high fatigue resistance in cyclic applications
• Trapezoidal wire shape increases load capacity within the same outer diameter envelope
• Blue color class indicates heavy-duty load rating per standard die spring classification
• 1,092 lb maximum deflection load with a 312 lb per inch spring rate
• 3.5 inches maximum deflection travel on a 7-inch free length body
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed for use in standard die sets and tooling assemblies accepting a 2-inch hole diameter and 1-inch guide rod diameter. Verify free length and deflection range against your specific tooling requirements before installation.

Installation Notes

Die springs of this type are installed by toolmakers or maintenance machinists in press and die applications. De-energize and lock out all press equipment before servicing any die components. Do not compress the spring beyond the rated maximum deflection of 3.5 inches, as overcompression will cause permanent set or failure. Inspect the spring seating surfaces for squareness and ensure the guide rod is smooth and within tolerance to prevent side loading during operation.
