Associated Spring Raymond 105-740 Die Spring Gold

Product Description

The ASSOCIATED SPRING RAYMOND 105-740 is a heavy-duty die spring designed for use in stamping dies, presses, and tooling fixtures. It features a trapezoidal wire cross-section that delivers higher load capacity and longer service life compared to round-wire springs of the same envelope size. The 105-740 carries a maximum deflection load of 1,032 pounds over a maximum deflection of 3 inches, with a spring rate of 362 pounds per inch. The gold color coding identifies this spring as a heavy-load series. Manufactured from chromium alloy steel, it is built to withstand the high-cycle fatigue demands of die and press tooling applications.

This die spring fits applications requiring a 1-1/2 inch hole diameter and 3/4 inch rod diameter with a free length of 10 inches. Typical install scenarios include punch and die sets, injection mold tooling, metal stamping fixtures, and industrial press components where consistent, repeatable spring force is required. The gold series designation is used across ISO-standard die spring sizing conventions, making it straightforward to cross-reference within tooling designs that specify load class by color.

Key Features

• Trapezoidal wire profile increases load density and fatigue resistance versus round-wire designs
• 1,032 pound maximum deflection load supports heavy-duty tooling requirements
• 3 inch maximum deflection with a 362 pound-per-inch spring rate for predictable force curves
• Gold color coding identifies heavy-load series per ISO die spring standards
• Chromium alloy steel construction for high-cycle durability in press and die environments
• ISO 9001:2008 and ISO/TS 16949:2009 certified manufacturing

Compatibility

Designed as a replacement or drop-in die spring for tooling fixtures requiring a 1-1/2 inch hole diameter, 3/4 inch rod diameter, and 10 inch free length in the heavy-load (gold) series per ISO die spring dimensional standards.

Installation Notes

Die springs are typically installed by toolmakers or maintenance technicians working on stamping or injection mold tooling. Before servicing any press or die set, relieve all hydraulic or mechanical pressure and lock out the press per applicable OSHA lockout/tagout procedures. Ensure the spring seats squarely on the rod and within the counterbore to prevent lateral loading. Do not compress the spring beyond the rated maximum deflection of 3 inches, as over-compression will reduce service life and may cause premature failure.
