Gibraltar DCIH12.5-51 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH12.5-51 is a heavy-duty die spring designed for use in stamping dies, press tooling, and industrial forming equipment. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a spring rate of 114 pounds per inch and a maximum deflection load of 108 pounds. The 2-inch free length and 0.5-inch hole diameter make it a compact, high-force component suited for tight tooling applications. It meets NAAMS and ISO 10243 international standards, making it a reliable choice for precision die applications requiring consistent force output. Qualified tool and die technicians and industrial maintenance professionals typically handle installation and replacement.

This die spring is intended for industrial tooling environments where controlled compression force is required over repeated cycles. It is commonly installed in stamping presses, injection mold assemblies, and other high-cycle die setups. The red color coding indicates a heavy-duty load rating per standard die spring classification. The 9/32-inch rod diameter and 0.5-inch hole diameter guide fit must be verified against existing tooling before installation. Compliance with NAAMS and ISO 10243 standards makes this part compatible with tooling designed to those specifications.

Key Features

• Heavy-duty load rating with a maximum deflection load of 108 pounds (480.60 N)
• Spring rate of 114 pounds per inch for consistent, predictable force output
• Trapezoidal wire cross-section for higher load capacity in a compact envelope
• Chromium alloy steel construction for durability under high-cycle industrial use
• Red color coding identifies heavy-duty duty rating per die spring industry standards
• Meets NAAMS, ISO 10243, and is manufactured under an ISO 9001:2015 registered quality system

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for stamping and forming tooling built to NAAMS or ISO 10243 standards with a 0.5-inch hole diameter and 9/32-inch rod diameter requirement.

Installation Notes

Die springs should be installed and replaced by qualified tool and die technicians or industrial maintenance personnel. Always de-energize and lock out the press or forming equipment before servicing any tooling components. Verify hole diameter, rod diameter, and free length match existing tooling specifications before installation. Do not compress a die spring beyond its rated maximum deflection of 0.94 inches to avoid permanent set or premature failure.
