Gibraltar DCIB20-89 Die Spring Extra Heavy-duty Yellow

Product Description

The GIBRALTAR DCIB20-89 is an extra heavy-duty die spring designed for use in stamping dies, molds, and high-cycle 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 free length of 3.5 inches, a 0.75-inch hole diameter, and a 0.375-inch rod diameter, this spring fits standard die sets and guided spring assemblies. At maximum deflection of 0.93 inches, it produces a load of 416 pounds at a spring rate of 448 pounds per inch. The yellow color coding identifies the extra heavy-duty duty rating per NAAMS and ISO 10243 standards. Installation is typically performed by toolmakers and die maintenance technicians.

This die spring is suited for metal stamping dies, injection mold tooling, and precision industrial fixtures that require consistent, high-force return action under repetitive cycling. The DCIB20-89 is used in both OEM die builds and maintenance replacement scenarios where the original spring must be matched by hole diameter, rod diameter, free length, and duty rating. Its chromium alloy steel construction maintains load performance across high-cycle fatigue conditions common in production stamping environments.

Key Features

• Extra heavy-duty duty rating with yellow color coding per NAAMS and ISO 10243 identification standards
• Trapezoidal wire cross-section maximizes load capacity within the spring envelope
• Chromium alloy steel construction for high-cycle fatigue resistance
• Maximum deflection load of 416 pounds at 0.93 inches of travel
• Spring rate of 448 pounds per inch for predictable, consistent force output
• Compliant with NAAMS, ISO 10243, and manufactured under ISO 9001:2015 registered quality systems

Compatibility

Designed as a standard-dimension replacement die spring for applications requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 3.5-inch free length in extra heavy-duty service. Dimensionally conforms to NAAMS and ISO 10243 international die spring standards.

Installation Notes

Die springs should be installed and replaced by qualified toolmakers or die maintenance technicians with the press or machine fully de-energized and locked out per OSHA lockout/tagout procedures. Inspect the mating bore and guide rod for wear or damage before installing a replacement spring. Do not exceed the maximum deflection of 0.93 inches during operation, as over-compression reduces fatigue life and can cause spring failure. Springs showing visible cracking, set, or corrosion should be replaced as a set rather than individually to maintain balanced tool performance.
