Gibraltar DCIM12.5-89 Die Spring Blue Medium-duty

Product Description

The GIBRALTAR DCIM12.5-89 is a medium-duty die spring designed for use in stamping dies, molds, and industrial tooling applications where consistent, reliable spring force is required. This spring features a 0.5 inch hole diameter, a 9/32 inch (0.2813 inch) rod diameter, and a 3.5 inch free length. Wound from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 78 pounds at 1.83 inches of travel. The blue color designation indicates medium-duty load class per industry standards. Installed by tool and die technicians, maintenance mechanics, and industrial engineers.

This die spring is suited for medium-load press and stamping die applications in both production and maintenance environments. Its trapezoidal wire profile maximizes load capacity relative to physical size, making it a practical choice for confined tooling spaces. The 3.5 inch free length and 1.83 inch maximum deflection suit it for a range of standard die set configurations where consistent spring return is critical to part quality and die longevity.

Key Features

• Medium-duty load rating with 78 pound maximum deflection load
• Trapezoidal wire cross-section for higher load density vs. round wire
• Chromium alloy steel construction for durability under cyclic loading
• Blue color coding for quick medium-duty identification at the die
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards
• Spring rate of 43 pounds per inch for predictable, linear force output

Compatibility

Designed as an OEM-style replacement die spring for medium-duty stamping dies, punch presses, and injection mold tooling that use 0.5 inch hole diameter, 9/32 inch rod diameter spring pockets with a 3.5 inch free length.

Installation Notes

Die springs are installed and serviced by tool and die technicians or qualified maintenance personnel. Always relieve all press and clamping pressure and lock out the press before removing or replacing die springs. Inspect the spring pocket and guide rod for wear or damage before installing a replacement. Do not exceed the rated maximum deflection of 1.83 inches to avoid premature fatigue failure.
