Gibraltar DCIM10-51 Die Spring Medium-duty Blue

Product Description

The GIBRALTAR DCIM10-51 is a medium-duty die spring designed for use in stamping dies, molds, and other precision tooling applications. Built from chromium alloy steel with a trapezoidal wire shape, it delivers a spring rate of 49.0 pounds per inch and a maximum deflection load of 55.0 pounds. The 2-inch free length compresses to a solid length of 1.13 inches, providing 1.13 inches of usable travel. The blue color coding identifies it as a medium-duty spring per industry convention. Licensed machinists, tool-and-die makers, and maintenance technicians are the primary installers of this component.

This spring fits applications where a 0.375-inch hole diameter and a 0.1875-inch rod diameter are required. It is suited for die sets, injection mold assemblies, punch presses, and similar tooling where repeatable, controlled force is needed over a defined stroke range. The compact 2-inch free length makes it appropriate for space-constrained tooling cavities requiring consistent medium-duty spring force.

Key Features

• Chromium alloy steel construction with trapezoidal wire cross-section for high load capacity in a compact envelope
• Medium-duty rating with a spring rate of 49.0 pounds per inch
• Maximum deflection load of 55.0 pounds (244.75 Newtons)
• 1.13 inches maximum deflection with a compressed solid length of 1.13 inches
• Blue color coding for quick medium-duty identification in mixed tooling environments
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as a standard replacement or original-fit die spring for tooling applications requiring a 0.375-inch hole diameter, a 0.1875-inch rod diameter, and a 2-inch free length in a medium-duty blue-series configuration.

Installation Notes

Die spring installation is typically performed by tool-and-die makers or qualified maintenance technicians during die assembly or scheduled maintenance. Power down and lock out all press or molding equipment before removing or installing springs. Inspect the mating pocket diameter and guide rod diameter against spring specifications before seating the spring. Never exceed the rated maximum deflection, as compressing a die spring beyond its travel-to-solid specification will rapidly fatigue the spring and shorten service life.
