Gibraltar DCIH20-76 Die Spring 3/4 in Hole 3 in Red Heavy-duty

Product Description

The GIBRALTAR DCIH20-76 is a heavy-duty die spring designed for use in stamping dies, molds, and industrial tooling applications. It features a trapezoidal wire cross-section wound from chromium alloy steel, which delivers higher load capacity in a compact envelope compared to round-wire springs. With a 3/4 inch hole diameter, 3/8 inch rod diameter, and 3 inch free length, this spring fits standard die sets and guided spring assemblies. It carries a maximum deflection load of 347 pounds and a maximum deflection of 0.97 inches, placing it firmly in the heavy-duty load category.

This spring is suited for industrial press tooling, injection mold assemblies, and die cushion applications where consistent, repeatable force is required over high cycle counts. The red color coding follows the ISO 10243 and NAAMS heavy-duty duty-rating convention, making it straightforward to identify the correct load class during tooling setup or replacement. It is typically installed and specified by tool and die makers, mold technicians, and maintenance machinists working in metal stamping or plastics processing environments.

Key Features

• Heavy-duty load rating with 347 pounds maximum deflection load
• Trapezoidal wire cross-section for higher load density versus round-wire equivalents
• Chromium alloy steel construction for fatigue resistance under high-cycle operation
• Red color coding per ISO 10243 heavy-duty classification for fast visual identification
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards
• 3/4 inch hole diameter and 3/8 inch rod diameter for compatibility with standard guided die spring assemblies

Compatibility

Designed as a standard replacement die spring for guided spring applications conforming to NAAMS and ISO 10243 dimensional standards with a 3/4 inch hole diameter, 3/8 inch rod diameter, and 3 inch free length in the heavy-duty load class.

Installation Notes

Die springs should be installed by qualified tool and die technicians or maintenance machinists familiar with press tooling safety procedures. Always depressurize and lock out the press or mold before removing or installing springs. Inspect the mating guide rod and bore for wear or misalignment before installation, as a damaged guide surface will accelerate spring fatigue. Do not compress the spring beyond the rated maximum deflection of 0.97 inches during installation or operation.
