Associated Spring Raymond 103-522 Die Spring Blue Medium-duty

Product Description

The ASSOCIATED SPRING RAYMOND 103-522 is a medium-duty die spring designed for use in stamping dies, presses, and tooling fixtures where consistent, repeatable force is required. Built from chromium alloy steel with a trapezoidal wire shape, it delivers a spring rate of 88 pounds per inch and handles a maximum deflection load of 242 pounds over a maximum deflection of 2.75 inches. The blue color coding follows the ISO standard for medium-duty classification, making identification fast during tooling setup and maintenance. This spring is installed by toolmakers, die setters, and maintenance technicians working in metal fabrication and industrial manufacturing environments.

This die spring fits applications requiring a 1 inch hole diameter and a 0.5 inch rod diameter, with a free length of 5.5 inches. It is suited for medium-duty press tooling, injection mold stripper plates, and general industrial die applications where controlled spring force and consistent deflection performance are critical to part quality and tool longevity. The chromium alloy steel construction supports repeated compression cycles under load without significant set loss.

Key Features

• Trapezoidal wire profile increases load capacity and fatigue life compared to round-wire springs of similar outer diameter
• Medium-duty blue color coding for fast visual identification in tooling environments
• 88 pounds-per-inch spring rate with a 242 pound maximum deflection load
• 2.75 inch maximum deflection allows precise travel control in die and fixture designs
• Chromium alloy steel construction for durability under cyclic compressive loading
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a standard medium-duty die spring for use in stamping dies, mold assemblies, and industrial tooling fixtures requiring a 1 inch hole diameter and a 0.5 inch rod diameter guide arrangement.

Installation Notes

Die springs are installed by toolmakers or maintenance technicians during die assembly or tooling maintenance. Always de-energize and lock out the press or machine before servicing any tooling. Ensure the guide rod diameter and pocket diameter match the spring specifications before installation to prevent buckling or premature wear. Do not compress the spring beyond the rated maximum deflection listed for this part.
