Associated Spring Raymond 103-312 Die Spring Medium-duty Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-312 is a medium-duty die spring designed for use in stamping dies, punch presses, and similar tooling applications. Built from chromium alloy steel with a trapezoidal wire profile, it delivers consistent load and deflection performance under repetitive cycling. The spring features a 0.625-inch hole diameter, an 11/32-inch rod diameter, and a 3-inch free length. It handles a maximum deflection load of 84 pounds over a maximum deflection of 1.5 inches, yielding a spring rate of 58 pounds per inch. Color coding in blue identifies the medium-duty load class at a glance on the shop floor.

This die spring is suited for production tooling environments where controlled compression force is required, including stamping, forming, and injection mold applications. It fits standard die sets calling for a 5/8-inch hole diameter and an 11/32-inch guide rod. Licensed tool and die makers, machine builders, and maintenance technicians handling press tooling are the typical installers. The compact 3-inch free length makes it appropriate for applications with limited daylight clearance in the die set.

Key Features

• Trapezoidal wire cross-section for higher load capacity relative to round-wire springs of similar size
• Chromium alloy steel construction for durability under high-cycle fatigue conditions
• Blue color coding indicates medium-duty load classification for quick visual identification
• 84-pound maximum deflection load with 1.5-inch maximum deflection travel
• Spring rate of 58 pounds per inch for predictable, linear compression behavior
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a standard-format die spring replacement for tooling applications requiring a 0.625-inch hole diameter and an 11/32-inch rod diameter guide pin with a 3-inch free length in the medium-duty blue load class.

Installation Notes

Installation is typically performed by tool and die makers or maintenance technicians servicing press tooling. Always de-energize and lock out the press before removing or installing die springs. Verify that the guide rod diameter and hole diameter of the die set match the spring specifications before assembly. Do not compress the spring beyond the rated maximum deflection of 1.5 inches, as over-compression will reduce service life and may cause spring failure.
