Gibraltar DCIM25-76 Die Spring Medium-duty Blue

Product Description

The GIBRALTAR DCIM25-76 is a medium-duty die spring designed for use in stamping dies, press tooling, and precision industrial fixtures. It features a 1-inch hole diameter, a 0.5-inch rod diameter, and a 3-inch free length, making it a standard-size component for die sets requiring consistent, reliable return force. Constructed from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 353 pounds at 1.26 inches of travel. The blue color coding identifies it as a medium-duty rating per ISO and NAAMS standards. Toolmakers, die setters, and industrial maintenance technicians install this type of component in production tooling environments.

This die spring is suited for stamping, forming, and blanking die applications in both production and maintenance settings. Its medium-duty rating makes it appropriate for moderate-load cycling applications where consistent spring force and dimensional repeatability are required. The trapezoidal wire profile increases load capacity relative to round wire springs of the same envelope size, which is an advantage in compact die spaces. Sold individually, it is a direct fit for standard die spring pockets calling for a 1-inch hole diameter and 0.5-inch guide rod.

Key Features

• 1-inch hole diameter and 0.5-inch rod diameter for standard die spring pocket fitment
• 3-inch free length with 1.26 inches of maximum deflection travel
• 353-pound maximum deflection load rating
• Trapezoidal wire cross-section for higher load density in compact tooling envelopes
• Chromium alloy steel construction for durability under repeated cycling
• Blue color coding per NAAMS and ISO 10243 medium-duty designation
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard die spring applications requiring a 1-inch hole diameter, 0.5-inch rod diameter, and 3-inch free length in medium-duty press and stamping tooling.

Installation Notes

Die spring installation and replacement should be performed by qualified toolmakers or die maintenance technicians with the press fully de-energized and ram safely blocked. Inspect the die pocket and guide rod for wear or damage before installing a new spring. Do not compress the spring beyond its rated maximum deflection of 1.26 inches, as over-compression will permanently reduce spring rate and service life. Follow applicable shop safety procedures and tooling manufacturer guidelines during die disassembly and reassembly.
