Associated Spring Raymond 103-308 Die Spring Medium-duty Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-308 is a medium-duty die spring designed for use in stamping dies, molds, and industrial tooling applications. It features a 0.625-inch hole diameter, an 11/32-inch rod diameter, and a 2-inch free length. The trapezoidal wire shape increases contact area and load capacity compared to round-wire springs of similar size, delivering a spring rate of 86 pounds per inch and a maximum deflection load of 88 pounds at 1 inch of travel. Manufactured from chromium alloy steel, this spring provides consistent performance under cyclic loading conditions. Installation is performed by tool and die makers, machine builders, and industrial maintenance technicians.

This die spring is suited for use in punch and die assemblies, injection mold tooling, press tooling, and other high-cycle industrial equipment where controlled compression force is required. The blue color coding identifies it as a medium-duty rating per industry die spring standards. It fits standard die spring pockets and guided rod assemblies sized for a 0.625-inch bore and 11/32-inch rod. The compact 2-inch free length suits applications with limited pocket depth or stroke requirements.

Key Features

• Medium-duty rating with 88-pound maximum deflection load at 1 inch maximum deflection
• Spring rate of 86 pounds per inch for predictable, linear force output
• Trapezoidal wire cross-section for increased load capacity and fatigue life
• Chromium alloy steel construction for durability under cyclic compressive loads
• Blue color coding identifies medium-duty classification at a glance
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a medium-duty die spring for standard guided rod and die pocket assemblies with a 0.625-inch hole diameter and an 11/32-inch rod diameter. Confirm pocket depth, rod diameter, and required load before installation.

Installation Notes

Installation is typically performed by tool and die makers or industrial maintenance technicians during die setup or tooling maintenance. De-energize and lock out all press or machine energy sources before accessing the die assembly. Ensure the rod diameter and pocket bore match the spring specifications before seating the spring. Do not compress the spring beyond its rated maximum deflection of 1 inch to avoid permanent set or premature failure.
