Gibraltar DCIB16-25 Die Spring 5/8 in Extra Heavy-duty Yellow

Product Description

The GIBRALTAR DCIB16-25 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 1 inch free length. Constructed from chromium alloy steel with a trapezoidal wire profile, it delivers a maximum deflection load of 242 pounds and a spring rate of 778 pounds per inch. The yellow color coding identifies its extra heavy-duty duty rating, allowing quick visual identification during press and die maintenance. Licensed machinists, tool and die makers, and mechanical maintenance technicians are the typical installers.

This die spring is suited for use in press tooling, punch and die assemblies, and other precision mechanical applications where consistent, high-force return loads are required. The trapezoidal wire shape maximizes load-bearing surface area within the spring coil, making it well-suited for tight tooling envelopes. It is sold individually and ships as a single-unit package, making it practical for direct replacement in existing die sets or new tooling builds.

Key Features

• Extra heavy-duty duty rating for demanding high-cycle tooling environments
• Chromium alloy steel construction for strength and fatigue resistance
• Trapezoidal wire cross-section maximizes load density in compact spaces
• 242 pound maximum deflection load with a 0.310 inch maximum deflection
• Spring rate of 778 pounds per inch for predictable, linear force output
• Yellow color coding for fast duty-rating identification on the shop floor

Compatibility

Designed as a standard die spring replacement conforming to NAAMS (North American Automotive Metric Standard) and ISO 10243 specifications, making it interchangeable with other NAAMS- and ISO 10243-compliant die springs of the same hole diameter, rod diameter, free length, and duty rating.

Installation Notes

Installation and replacement should be performed by qualified tool and die or mechanical maintenance personnel with the press or machine fully de-energized and locked out per applicable OSHA lockout/tagout procedures. Ensure the rod diameter and hole diameter clearances match the existing die set before installation. Do not compress the spring beyond its rated maximum deflection of 0.310 inch, as overcompression will reduce fatigue life and can cause premature failure. Inspect the spring seat and guide rod for wear or damage before installing a replacement spring.
