Associated Spring Raymond 105-307 Die Spring Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 105-307 is a heavy-duty die spring designed for use in stamping dies, punch presses, and tooling fixtures where consistent, reliable force is required under repeated compression cycles. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 240 pounds per inch and a maximum deflection load of 126 pounds at 0.53 inches of travel. The gold color coding identifies this spring as a heavy-duty unit per standard die spring classification. It is installed by tool and die makers, machine builders, and maintenance technicians working on press tooling and industrial fixtures.

The 105-307 fits applications requiring a 0.625-inch hole diameter and an 11/32-inch rod diameter, with a free length of 1.75 inches. This spring is suited for use in progressive dies, compound dies, stripping operations, and other precision tooling where controlled load deflection is critical. Its chromium alloy steel construction handles the high-cycle fatigue demands common in production stamping environments. Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 quality management systems, it meets the dimensional and performance standards expected in industrial tooling applications.

Key Features

• Trapezoidal wire cross-section increases load capacity and fatigue life compared to round wire die springs
• Spring rate of 240 pounds per inch provides predictable, consistent force output
• Maximum deflection load of 126 pounds at 0.53 inches of travel
• Gold color coding identifies heavy-duty duty rating per standard die spring classification
• Chromium alloy steel construction for high-cycle durability in production tooling
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a standard heavy-duty die spring for tooling fixtures, stamping dies, and punch press applications requiring a 0.625-inch hole diameter, an 11/32-inch rod diameter, and a 1.75-inch free length.

Installation Notes

Die springs should be installed by qualified tool and die technicians or maintenance personnel familiar with press tooling. Always de-energize and lock out the press before replacing springs in a die assembly. Ensure the rod diameter and hole diameter clearances match the spring specifications before installation to prevent buckling or binding during operation. Do not compress the spring beyond its rated maximum deflection, as over-compression significantly reduces fatigue life.
