Associated Spring Raymond 106-516 Die Spring Extra Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 106-516 is an extra heavy-duty die spring designed for high-load tooling and stamping applications. It features a 1 inch hole diameter, a 0.5 inch rod diameter, and a 4 inch free length, with a trapezoidal wire cross-section that delivers a consistent 552 pound spring rate across its full travel range. Constructed from chromium alloy steel, this spring is built to withstand the compressive stress cycles common in metal stamping dies, injection molds, and industrial press tooling. The green color coding identifies its extra heavy-duty duty rating per international die spring standards.

This spring is suited for use in metal stamping dies, progressive dies, injection mold tooling, and other industrial applications that require a compact, high-load compression spring. It fits over a 0.5 inch guide rod inside a 1 inch bore pocket, making it a direct fit for standard die sets following ISO and metric-compatible tooling layouts. Typical installers include tool-and-die makers, mold technicians, and mechanical maintenance engineers working in production manufacturing environments.

Key Features

• Extra heavy-duty duty rating with a 552 pound maximum deflection load
• Trapezoidal wire shape for higher load capacity versus round wire springs of the same envelope
• Chromium alloy steel construction for fatigue resistance under cyclic compression
• Green color coding for quick duty-rating identification at the die or press
• 1 inch maximum deflection at full rated load
• 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 direct-fit die spring for standard tooling bores requiring a 1 inch hole diameter, 0.5 inch rod diameter, and 4 inch free length in an extra heavy-duty green classification.

Installation Notes

Installation is typically performed by tool-and-die makers or mechanical technicians during die maintenance or build. Always de-energize and lock out the press before removing or installing die springs. Seat the spring fully in the pocket bore and confirm the guide rod engages cleanly without lateral binding. Do not exceed the rated maximum deflection of 1 inch, as over-compression accelerates fatigue failure and shortens service life.
