Gibraltar DCIB12.5-25 Die Spring Extra Heavy-duty Yellow

Product Description

The GIBRALTAR DCIB12.5-25 is an extra heavy-duty die spring designed for use in stamping dies, molds, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire shape, this spring delivers a spring rate of 312 pounds per inch and a maximum deflection load of 109 pounds. Its yellow color coding identifies the extra heavy-duty duty rating at a glance, which is standard across NAAMS and ISO 10243 die spring classifications. Licensed tool-and-die technicians and industrial maintenance professionals typically specify this part when high-force, short-stroke spring return is required in a compact envelope.

This die spring suits applications in stamping and forming dies, injection molds, jigs, and fixtures where reliable return force and consistent cycling are critical. With a 0.5-inch hole diameter and a 9/32-inch rod diameter, it is sized for standard guided-rod installations. The 1-inch free length and 0.35-inch maximum deflection make it appropriate for tight tooling clearances in both production and repair scenarios. It is sold individually, making it practical for single-position replacement without committing to bulk quantities.

Key Features

• Extra heavy-duty duty rating with 109-pound maximum deflection load
• Trapezoidal wire cross-section for higher load capacity relative to round-wire springs of comparable size
• Chromium alloy steel construction for fatigue resistance under high-cycle conditions
• Yellow color coding conforms to NAAMS and ISO 10243 duty-rating identification standards
• Spring rate of 312 pounds per inch provides firm, predictable return force
• Compliant with NAAMS, ISO 10243, and manufactured under ISO 9001:2015 registered quality systems

Compatibility

Designed as a standard-specification replacement die spring for guided-rod tooling installations requiring a 0.5-inch hole diameter, a 9/32-inch rod diameter, and a 1-inch free length in an extra heavy-duty rating per NAAMS and ISO 10243 dimensional standards.

Installation Notes

Die spring replacement is typically performed by tool-and-die technicians or industrial maintenance personnel with the press or mold fully de-energized and all stored mechanical energy safely released. The spring must be installed on an appropriate guide rod sized for the 9/32-inch rod diameter to prevent buckling during compression. Inspect the rod and bore for wear or damage before installing a replacement spring. Follow applicable facility lockout/tagout procedures before servicing any tooling.
