Gibraltar DCIB50-178 Die Spring 7in Extra Heavy-duty Yellow

Product Description

The GIBRALTAR DCIB50-178 is an extra heavy-duty die spring engineered for high-load industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 2,808 pounds and a spring rate of 1,193 pounds per inch. The 7-inch free length, 2-inch hole diameter, and 1-inch rod diameter make it a direct fit for standard die sets and stamping press tooling. At 2.5 pounds, it is a robust component designed to withstand repeated high-stress cycling in production environments. Toolmakers, die setters, and maintenance machinists are the primary installers of this component.

This die spring is suited for use in metal stamping dies, injection mold tooling, and industrial press applications requiring extra heavy-duty force ratings. The yellow color coding follows the ISO 10243 international standard for load classification, allowing quick visual identification of spring duty rating on the shop floor or in tool cribs. It is appropriate for both automotive and general manufacturing die applications where consistent high-force return is required under compressed cycle conditions.

Key Features

• Extra heavy-duty duty rating with a maximum deflection load of 2,808 pounds
• Chromium alloy steel construction with trapezoidal wire profile for high fatigue resistance
• Spring rate of 1,193 pounds per inch for consistent, predictable force output
• 2-inch hole diameter and 1-inch rod diameter for standard die set fitment
• 7-inch free length with a maximum deflection of 2.35 inches
• Yellow color coding per ISO 10243 load classification standard

Compatibility

Designed as an OEM-style replacement die spring for extra heavy-duty industrial stamping dies, press tooling, and mold assemblies requiring a 2-inch hole diameter, 1-inch rod diameter, and 7-inch free length configuration conforming to NAAMS and ISO 10243 standards.

Installation Notes

Die springs of this type are installed and serviced by qualified toolmakers or die maintenance technicians. Always de-energize and lock out the press before servicing any die component. Inspect the mating rod and pocket bore for wear or damage before installing a replacement spring. Never compress the spring beyond its rated maximum deflection to avoid permanent set or premature fatigue failure.
