Gibraltar DCIB50-89 Die Spring Extra Heavy-duty Yellow

Product Description

The GIBRALTAR DCIB50-89 is an extra heavy-duty die spring designed for high-load tooling and press applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 3,023 pounds across a 1.17-inch travel range. The 2-inch hole diameter and 1-inch rod diameter make it a direct fit for standard die set configurations. Color-coded yellow per ISO 10243 conventions for quick identification of extra heavy-duty duty rating. Licensed HVAC technicians, tool-and-die makers, and maintenance professionals working on stamping and forming equipment are the typical installers of this spring type.

This spring is suited for use in industrial die sets, punch press tooling, injection mold assemblies, and similar high-cycle mechanical applications where consistent return force and long fatigue life are required. With a free length of 3.5 inches and a spring rate of 2,576 pounds per inch, it is appropriate for applications demanding high load capacity in a compact envelope. It meets NAAMS and ISO 10243 dimensional standards, making it interchangeable within compliant tooling designs used across automotive, aerospace, and general manufacturing environments.

Key Features

• Extra heavy-duty duty rating with a maximum deflection load of 3,023 pounds
• Trapezoidal wire cross-section for increased load capacity relative to round-wire springs of the same envelope
• Chromium alloy steel construction for durability in high-cycle press environments
• Yellow color coding per ISO 10243 for fast visual identification of duty class
• Compliant with NAAMS and ISO 10243 standards for direct dimensional interchangeability
• Spring rate of 2,576 pounds per inch across a maximum deflection of 1.17 inches

Compatibility

Designed as an ISO 10243 and NAAMS-compliant replacement die spring for tooling assemblies requiring a 2-inch hole diameter, 1-inch rod diameter, and 3.5-inch free length in an extra heavy-duty rating class.

Installation Notes

Die springs of this type are installed and serviced by qualified tool-and-die technicians or maintenance personnel. Always de-energize and lockout-tagout the press or forming machine before removing or installing springs. Inspect the mating rod and hole bores for wear or damage before seating the replacement spring. Never compress the spring beyond its rated maximum deflection of 1.17 inches to avoid permanent set or fatigue failure.
