Gibraltar DCIB40-102 Die Spring 1927 Lb Extra Heavy-duty

Product Description

The GIBRALTAR DCIB40-102 is an extra heavy-duty die spring engineered for high-load stamping, pressing, and tooling die applications. It features a trapezoidal wire cross-section wound from chromium alloy steel, which delivers higher load capacity and longer service life compared to round-wire springs of the same envelope size. The spring carries a maximum deflection load of 1927 pounds and a spring rate of 1563 pounds per inch, making it suitable for demanding metal-forming and injection-mold operations. It is sold individually and is ready for direct installation into standard die sets and tooling fixtures.

This spring is designed for use in industrial tooling, progressive dies, stamping dies, molds, and related fixturing where consistent, repeatable force is required over extended production cycles. The yellow color coding identifies the extra heavy-duty load class per ISO 10243, allowing quick visual identification during die maintenance. Maintenance technicians, tool-and-die makers, and mold repair specialists are the primary installers in both automotive and general manufacturing environments.

Key Features

• Extra heavy-duty duty rating with 1927 lb maximum deflection load
• Trapezoidal wire profile for higher load density within a compact envelope
• Chromium alloy steel construction for fatigue resistance and extended cycle life
• Yellow color coding per ISO 10243 extra heavy-duty class for fast visual identification
• Compliant with NAAMS, ISO 10243, and manufactured under ISO 9001:2015 registered quality standards
• 1.23 inches maximum deflection with a travel-to-solid load of approximately 1.2165 inches

Compatibility

Designed as a standard replacement or new-installation die spring for tooling die sets and fixtures requiring a 1.5-inch hole diameter, 0.75-inch rod diameter, and 4-inch free length in the extra heavy-duty (yellow) load class per ISO 10243 and NAAMS specifications.

Installation Notes

Installation is typically performed by a tool-and-die maker or qualified maintenance technician. Ensure the mating die set or fixture is fully de-energized and all hydraulic or mechanical press energy is dissipated before replacing springs. Verify that the bore diameter and rod diameter of the tooling match the spring envelope before installation to prevent side-loading, which can reduce fatigue life. Inspect the spring seat surfaces for burrs or damage that could cause uneven seating.
