Gibraltar DCIB25-76 Die Spring 3 Inch Yellow Extra Heavy-duty

Product Description

The GIBRALTAR DCIB25-76 is an extra heavy-duty die spring designed for high-load tooling and stamping applications. It features a 1-inch hole diameter, a 0.5-inch rod diameter, and a 3-inch free length. The spring is wound from chromium alloy steel with a trapezoidal wire profile, which distributes stress more evenly than round wire and supports a maximum deflection load of 701 pounds. The yellow color coding indicates extra heavy-duty duty rating per industry convention. This part is installed by tool and die makers, mold technicians, and maintenance machinists working on press tooling, injection molds, and progressive die assemblies.

This die spring is suited for use in industrial press tooling, stamping dies, injection mold assemblies, and fixture applications where consistent, high spring force is required across repeated compression cycles. The compact 3-inch free length makes it practical for installations with limited vertical space. It is appropriate for both new tooling builds and replacement applications in existing die sets requiring an extra heavy-duty spring with a 1-inch bore.

Key Features

• Extra heavy-duty duty rating with a maximum deflection load of 701 pounds
• Trapezoidal wire cross-section for improved load distribution and fatigue resistance
• Chromium alloy steel construction for strength and durability under repeated cycling
• 1-inch hole diameter and 0.5-inch rod diameter for straightforward die set fitment
• Maximum deflection of 0.95 inches at full load
• Yellow color coding for quick duty-rating identification in the field
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement die spring for extra heavy-duty tooling applications requiring a 1-inch hole diameter, 0.5-inch rod diameter, and 3-inch free length in chromium alloy steel construction.

Installation Notes

Installation is performed by qualified tool and die technicians or maintenance machinists. Always relieve all press pressure and lock out the ram before removing or installing die springs. Inspect the mating rod and bore for burrs or wear that could cause uneven loading or premature spring failure. Do not compress the spring beyond the rated maximum deflection of 0.95 inches, as over-compression accelerates fatigue and can cause sudden failure.
