Gibraltar DCIH25-127 Heavy-duty Die Spring 5 in Red

Product Description

The GIBRALTAR DCIH25-127 is a heavy-duty die spring designed for high-load tooling and stamping applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 639 pounds and a spring rate of 361 pounds per inch. The 5-inch free length compresses to a solid height of approximately 1.77 inches at full load, with a maximum deflection of 1.77 inches. The red color coding identifies it as a heavy-duty rating per industry convention. Licensed millwrights, tool and die technicians, and maintenance mechanics typically specify and install this spring in press tooling, molds, and die sets.

This spring is suited for industrial press tooling, injection mold assemblies, and automated stamping equipment where consistent, repeatable spring force is required. The 1-inch hole diameter accepts a 0.5-inch rod, making it compatible with standard die set configurations in both production and maintenance environments. Its compliance with NAAMS and ISO 10243 standards makes it a recognized choice for automotive and precision manufacturing tooling applications.

Key Features

• Heavy-duty rating with 639-pound maximum deflection load
• Trapezoidal wire profile for higher load capacity in a compact envelope
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• Red color coding for quick identification of duty rating on the shop floor
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards
• 1-inch hole diameter with 0.5-inch rod diameter for standard die set fitment

Compatibility

Designed as a replacement or upgrade die spring for standard NAAMS and ISO 10243 compliant die sets and press tooling with a 1-inch bore and 1/2-inch rod diameter.

Installation Notes

Installation should be performed by qualified tool and die technicians or maintenance mechanics familiar with press tooling safety procedures. Always de-energize and lock out the press before removing or replacing die springs. Inspect the rod diameter and bore for burrs or wear before seating the spring to prevent premature fatigue. Do not exceed the rated maximum deflection of 1.77 inches during operation.
