Associated Spring Raymond 103-348 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-348 is a medium-duty die spring designed for use in stamping dies, punch presses, and other tooling applications that demand consistent, repeatable force under cyclic compression. Built from chromium alloy steel with a trapezoidal wire shape, this spring delivers a spring rate of 15 pounds per inch and handles a maximum deflection load of 96 pounds over a maximum deflection of 6 inches. The blue color coding identifies it as a medium-duty rating per standard die spring classification. It is installed and maintained by tooling technicians, die setters, and mechanical maintenance professionals.

This spring fits applications requiring a 0.625-inch hole diameter and an 11/32-inch rod diameter, with a 12-inch free length. It is suited for use in hydraulic and mechanical press tooling, injection mold assemblies, and industrial die sets where controlled return force and long fatigue life are required. The compact geometry and standard sizing make it a direct fit in most medium-duty die sets calling for blue-coded springs at this dimensional range.

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 at the same outside diameter
• Blue color code indicates medium-duty rating for quick identification during die setup
• 15 pounds per inch spring rate provides consistent, predictable force output
• Maximum deflection load of 96 pounds at 6 inches of deflection
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as an OEM-style replacement or new-installation die spring for medium-duty tooling applications requiring a 0.625-inch hole diameter, 11/32-inch rod diameter, and 12-inch free length with a blue medium-duty rating.

Installation Notes

Die springs should be installed by qualified tooling or mechanical maintenance personnel familiar with press and die set safety procedures. Always de-energize and lock out the press before removing or installing die components. Do not compress the spring beyond its rated maximum deflection of 6 inches, as over-deflection will shorten fatigue life and may cause premature failure. Inspect the spring seating surfaces for burrs or damage before installation to ensure even load distribution.
