Associated Spring Raymond 105-516 Heavy-duty Die Spring

Product Description

The ASSOCIATED SPRING RAYMOND 105-516 is a heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a 1 inch hole diameter, a 1/2 inch rod diameter, and a 4 inch free length, making it suitable for high-load compression applications. Constructed from chromium alloy steel with a trapezoidal wire profile, this spring delivers a spring rate of 400 pounds per inch and a maximum deflection load of 480 pounds at 1.2 inches of maximum deflection. The gold color coding identifies the heavy-duty load rating per standard die spring classification. This component is installed by tool and die makers, press technicians, and maintenance machinists in manufacturing environments.

This die spring is used in metal stamping, forming, and stripping operations where consistent, repeatable spring force is required. It fits standard die sets with a 1 inch bore and a 1/2 inch guide rod. Typical applications include stripper plates, pressure pads, and return mechanisms in progressive and compound dies. Its heavy-duty rating makes it appropriate for high-cycle tooling where lighter-duty springs would fatigue prematurely.

Key Features

• Heavy-duty load rating with a maximum deflection load of 480 pounds
• Trapezoidal wire cross-section for higher load capacity compared to round-wire springs of the same envelope
• Chromium alloy steel construction for fatigue resistance in high-cycle tooling
• Gold color coding for quick identification of heavy-duty duty rating
• Spring rate of 400 pounds per inch for predictable, linear force output
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed for use in standard die sets with a 1 inch hole diameter and a 1/2 inch guide rod diameter. Suitable as a direct replacement or new installation in heavy-duty stamping and forming tooling that requires a 4 inch free-length compression spring in this bore and rod envelope.

Installation Notes

Die springs should be installed by qualified tool and die technicians following established press safety procedures. Always de-energize and lock out the press before servicing any die components. Do not exceed the rated maximum deflection of 1.2 inches, as over-compression accelerates fatigue and can cause premature failure. Inspect springs for set, cracking, or corrosion at scheduled die maintenance intervals.
