Associated Spring Raymond 105-312 Die Spring Heavy-duty Gold

Product Description

The ASSOCIATED SPRING RAYMOND 105-312 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. It features a 0.625 inch hole diameter, an 11/32 inch rod diameter, and a 3 inch free length. The trapezoidal wire shape delivers a higher spring rate compared to round-wire designs, with a rated spring rate of 140 pounds per inch and a maximum deflection load of 129.6 pounds at 0.9 inches of travel. Manufactured from chromium alloy steel, it is finished in gold to indicate heavy-duty duty rating per industry color-coding conventions. Licensed machinists, tool-and-die makers, and maintenance technicians working on press tooling are the typical installers.

This die spring is suited for heavy-duty industrial press tooling environments where consistent, repeatable force is required over high cycle counts. It is sized to fit standard die sets requiring a 0.625 inch hole diameter and an 11/32 inch guide rod. Typical applications include stripping, clamping, pressure pads, and ejector functions inside progressive, compound, or transfer dies. The gold color coding allows quick identification of spring duty class during tooling setup and maintenance.

Key Features

• Heavy-duty duty rating identified by gold color coding per standard die spring classification
• Trapezoidal wire shape provides higher load capacity and longer fatigue life compared to round-wire springs
• Spring rate of 140 pounds per inch for predictable, consistent force delivery
• Maximum deflection load of 129.6 pounds at 0.9 inches maximum deflection
• Chromium alloy steel construction for high-cycle durability under press tooling conditions
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for industrial stamping and punch press tooling requiring a 0.625 inch hole diameter, 11/32 inch rod diameter, and 3 inch free length in the heavy-duty classification.

Installation Notes

Die spring installation and replacement should be performed by qualified tool-and-die technicians or maintenance personnel with the press fully de-energized, locked out, and tagged out per OSHA lockout/tagout procedures. Verify hole diameter, rod diameter, free length, and duty rating match the tooling specification before installation. Do not exceed the published maximum deflection of 0.9 inches, as over-compression will reduce fatigue life and can cause premature failure. Inspect guide rods and die set bores for wear or misalignment before installing a replacement spring.
