Gibraltar DCIB16-64 Die Spring 2.5in Extra Heavy-duty Yellow

Product Description

The GIBRALTAR DCIB16-64 is an extra heavy-duty die spring designed for high-load tooling and stamping applications. It features a 5/8 inch hole diameter, an 11/32 inch rod diameter, and a 2.5 inch free length. Wound from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 229 pounds and a maximum deflection of 0.83 inches. The yellow color coding identifies the extra heavy-duty duty rating at a glance, consistent with industry-standard die spring classification. It is sold individually and suited for precision die and mold work where consistent spring force and durability are critical.

This die spring is intended for use in stamping dies, injection molds, and similar industrial tooling assemblies. It performs in applications requiring high compressive force within a compact envelope. The extra heavy-duty rating makes it appropriate for high-cycle production tooling where lighter-duty springs would fatigue prematurely. Machinists, tool-and-die makers, and maintenance technicians working on press tooling are the primary installers.

Key Features

• Extra heavy-duty duty rating with yellow color coding for fast field identification
• Trapezoidal wire cross-section for higher load capacity versus round-wire springs of the same envelope
• Chromium alloy steel construction for fatigue resistance in high-cycle tooling environments
• Maximum deflection load of 229 pounds at 0.83 inches of travel
• Spring rate of 274 pounds per inch for predictable, linear force progression
• Compliant with NAAMS, ISO 10243, and manufactured under ISO 9001:2015 registered quality standards

Compatibility

Designed as a standard-profile die spring for use in stamping dies, molds, and industrial tooling assemblies requiring a 5/8 inch hole diameter and 11/32 inch rod diameter with a 2.5 inch free length.

Installation Notes

Installation is performed by tool-and-die makers or maintenance machinists during die assembly or tooling maintenance. Confirm the mating hole diameter and guide rod diameter match the spring specifications before installation to prevent binding or misalignment. Always relieve all press or clamp pressure and lock out the press before servicing die components. Do not compress the spring beyond its rated maximum deflection of 0.83 inches, as over-compression will reduce service life and can cause premature failure.
