Gibraltar DCIB40-89 Die Spring Extra Heavy-duty Yellow

Product Description

The GIBRALTAR DCIB40-89 is an extra heavy-duty die spring designed for use in stamping dies, punch presses, and other high-load tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 1863 pounds and a maximum deflection of 1.04 inches. The yellow color coding identifies the extra heavy-duty load rating in accordance with ISO 10243 classification standards. This spring is installed by tool and die makers, machine builders, and maintenance technicians working with industrial press tooling.

This die spring fits applications requiring a 1.5-inch hole diameter and a 0.75-inch rod diameter. The 3.5-inch free length suits medium-stroke tooling setups where high force is needed within a compact envelope. Typical installations include injection molds, stamping dies, forming tools, and other precision tooling where consistent spring force and deflection are critical. The spring rate of 1793 pounds per inch supports predictable, repeatable performance across production cycles.

Key Features

• Extra heavy-duty load rating with a maximum deflection load of 1863 pounds
• Chromium alloy steel construction with trapezoidal wire shape for high load capacity and fatigue resistance
• Spring rate of 1793 pounds per inch for consistent, repeatable force output
• Yellow color coding per ISO 10243 for fast visual identification of duty class
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards
• 1.5-inch hole diameter and 0.75-inch rod diameter for standard tooling fitment

Compatibility

Designed as a standard-dimension die spring for industrial stamping dies, punch presses, injection molds, and forming tooling requiring a 1.5-inch hole diameter, 0.75-inch rod diameter, and 3.5-inch free length with an extra heavy-duty load rating.

Installation Notes

Die springs are installed by qualified tool and die technicians or machine maintenance personnel. Before servicing any tooling, de-energize and lock out the press or machine per OSHA lockout/tagout procedures. Verify that the mounting hole diameter and rod diameter match the spring dimensions before installation. Do not compress the spring beyond the rated maximum deflection of 1.04 inches, as exceeding the travel-to-solid limit can cause permanent set or premature failure.
