Associated Spring Raymond 103-505 Die Spring Medium Duty Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-505 is a medium-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a trapezoidal wire shape that delivers higher load capacity relative to round-wire springs of the same envelope size. With a 1 inch hole diameter, a 0.5 inch rod diameter, and a 1.25 inch free length, this spring fits standard die set configurations. The blue color coding indicates medium-duty classification per ISO and industry-standard die spring conventions. Maximum deflection load is 281.3 pounds at 0.63 inches of deflection, with a spring rate of 450 pounds per inch. The body is manufactured from chromium alloy steel for durability under cyclic compressive loading.

The 103-505 is suited for use in metal stamping dies, injection mold assemblies, and general industrial press tooling where consistent, repeatable spring force is required. Blue-coded medium-duty die springs are a common selection for moderate-load stripping and pressure pad applications. This spring is appropriate for both OEM die builds and maintenance replacement in production tooling environments. Tool and die makers, mold builders, and industrial maintenance technicians are the typical installers.

Key Features

• Trapezoidal wire cross-section for higher load capacity in a compact envelope
• Blue color coding denotes medium-duty classification per standard die spring ratings
• 281.3 pound maximum deflection load at 0.63 inches maximum deflection
• Spring rate of 450 pounds per inch for predictable, linear force output
• Chromium alloy steel construction resists fatigue under high-cycle compressive loading
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or new-build component for standard die sets and press tooling that accept a 1 inch hole diameter, 0.5 inch rod diameter die spring with a 1.25 inch free length.

Installation Notes

Die spring installation is typically performed by tool and die makers or industrial maintenance technicians during die build or tooling service. Always de-energize and lock out the press before removing or replacing die springs. Ensure the mating rod diameter and pocket diameter match the spring specifications before installation. Do not compress a die spring beyond its rated maximum deflection, as overcompression accelerates fatigue failure and reduces service life.
