Gibraltar DCIM25-51 Die Spring 2 in Medium-duty Blue

Product Description

The GIBRALTAR DCIM25-51 is a medium-duty die spring designed for use in stamping dies, press tools, and industrial tooling fixtures. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 354 pounds across a maximum deflection of 0.83 inches. The free length measures 2 inches, the hole diameter is 1 inch, and the rod diameter is 0.5 inches. This spring is color-coded blue to indicate its medium-duty rating, making it easy to identify and match during tooling maintenance. It is sold individually and is the right part for tool-and-die makers, press operators, and maintenance technicians working in industrial manufacturing environments.

This die spring is suited for use in progressive dies, compound dies, and other press tooling applications requiring controlled, consistent spring force. The blue color code follows the industry-standard duty classification system, allowing straightforward cross-referencing during tooling setups and replacements. Its chromium alloy steel construction handles the repeated compression cycles typical in high-volume stamping operations. The spring rate of 426 pounds per inch provides predictable force characteristics across the working stroke.

Key Features

• Medium-duty rating, color-coded blue for fast identification in tooling applications
• Chromium alloy steel construction with trapezoidal wire cross-section for extended cycle life
• Maximum deflection load of 354 pounds with a spring rate of 426 pounds per inch
• 2-inch free length with a maximum deflection of 0.83 inches and compressed solid length of 0.83 inches
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards
• 1-inch hole diameter and 0.5-inch rod diameter for standard die tooling compatibility

Compatibility

Designed as an OEM-style replacement die spring for use in stamping die assemblies and press tooling fixtures that call for a medium-duty, blue-coded spring with a 1-inch hole diameter and 0.5-inch rod diameter.

Installation Notes

Installation should be performed by qualified tool-and-die technicians or maintenance personnel with appropriate press safety training. De-energize and lock out the press completely before accessing the die set or replacing springs. Verify the hole diameter and rod diameter clearances match the tooling before compressing the spring into position. Never exceed the rated maximum deflection to avoid set or premature fatigue failure.
