Gibraltar DCIB12.5-76 Die Spring Extra Heavy-duty Yellow

Product Description

The GIBRALTAR DCIB12.5-76 is an extra heavy-duty die spring designed for high-load tooling and press applications in industrial and manufacturing environments. Wound from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a rated spring rate of 95 pounds per inch and a maximum deflection load of 106 pounds. The trapezoidal wire profile increases active coil surface area, improving load capacity and fatigue resistance compared to round-wire springs of equivalent size. Typical installers include tool-and-die technicians, press maintenance mechanics, and industrial maintenance professionals working with stamping dies, injection molds, and similar tooling.

This die spring is suited for use in stamping dies, punching presses, molds, and other repetitive-cycle industrial tooling where consistent force and long service life are required. The yellow color coding indicates extra heavy-duty load class per ISO 10243 and NAAMS standards, making it straightforward to identify and source replacements during scheduled die maintenance. With a free length of 3 inches, a hole diameter of 0.5 inches, and a rod diameter of 0.28 inches, it fits standard die spring pockets of compatible dimensions.

Key Features

• Extra heavy-duty duty rating with a maximum deflection load of 106 pounds (471.70 N)
• Trapezoidal wire cross-section for higher load density and improved fatigue life
• Chromium alloy steel construction for durability under repeated compression cycles
• Yellow color coding per ISO 10243 and NAAMS standards for easy load-class identification
• Maximum deflection of 1.12 inches with a compressed solid length of 1.12 inches
• Compliant with NAAMS, ISO 10243, and manufactured under ISO 9001:2015 registered quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for standard industrial tooling applications requiring a 0.5 inch hole diameter, 0.28 inch rod diameter, and 3 inch free length extra heavy-duty spring conforming to ISO 10243 and NAAMS dimensional standards.

Installation Notes

Die spring replacement and installation should be performed by qualified tool-and-die or industrial maintenance personnel with the press or tooling fully de-energized, locked out, and secured against unexpected actuation per applicable LOTO procedures. Inspect the spring pocket and guide rod for wear, burrs, or misalignment before installing the new spring. Do not compress the spring beyond its rated maximum deflection of 1.12 inches, as exceeding this limit reduces service life and risks spring failure. Replacement springs should be installed with the same orientation and seating as the original component.
