Associated Spring Raymond 106-104 Die Spring Extra Heavy Duty

Product Description

The ASSOCIATED SPRING RAYMOND 106-104 is an extra heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a 3/8 inch hole diameter, a 3/16 inch rod diameter, and a 1 inch free length. The trapezoidal wire shape maximizes load capacity within a compact envelope, delivering a spring rate of 210 pounds per inch and a maximum deflection load of 55 pounds. Constructed from chromium alloy steel, it offers superior fatigue resistance and consistent performance under repeated high-load cycling. Color coded green to indicate extra heavy-duty classification, making identification fast during setup and maintenance.

This die spring is used in metal stamping, die casting support, injection mold tooling, and similar industrial press applications where consistent spring force and precise deflection control are critical. The compact 1 inch free length suits tight tool clearances. It is typically specified by tool and die makers, machine builders, and maintenance technicians working on progressive dies, compound dies, or stripping mechanisms that require reliable, repeatable spring return force.

Key Features

• Extra heavy-duty duty rating with a maximum deflection load of 55 pounds
• Spring rate of 210 pounds per inch for consistent, predictable force output
• Maximum deflection of 0.25 inches within a 1 inch free length
• Trapezoidal wire cross-section maximizes load capacity versus coil diameter
• Chromium alloy steel construction for high fatigue life under cyclic loading
• Green color coding for fast visual identification of extra heavy-duty classification

Compatibility

Designed as a standard-dimension replacement die spring for tooling applications requiring a 3/8 inch hole diameter and 3/16 inch rod diameter with a 1 inch free length in the extra heavy-duty load class.

Installation Notes

Die springs are installed by tool and die professionals or maintenance technicians servicing press tooling. Always de-energize and lockout the press before replacing springs within a die set. Ensure the mating rod and pocket dimensions match the specified rod and hole diameters to prevent spring buckling or bore contact during compression. Do not compress the spring beyond the rated maximum deflection of 0.25 inches to avoid permanent set or premature failure.
