Gibraltar DCIB40-76 Die Spring 1865 Lb Extra Heavy-duty Yellow

Product Description

The GIBRALTAR DCIB40-76 is an extra heavy-duty die spring designed for use in stamping dies, presses, and industrial tooling applications. It features a trapezoidal wire cross-section wound from chromium alloy steel, which delivers a higher spring rate and greater load capacity compared to standard round-wire springs of the same envelope size. The spring has a 1.5-inch hole diameter, a 0.75-inch rod diameter, and a 3-inch free length. At maximum deflection of 0.87 inches, it produces a load of 1,865 pounds. The spring rate is 2,134 pounds per inch. Licensed trades and tooling engineers install this part in production and maintenance environments.

This die spring is suited for heavy industrial press tooling, stamping dies, and mechanical assemblies where high cyclic load and consistent force are required. The yellow color coding identifies the extra heavy-duty load category per ISO and NAAMS standards, making it straightforward to identify and replace within a mixed-spring tooling setup. It fits standard 1.5-inch bore pockets with 0.75-inch guide rods, which are common configurations in automotive and general manufacturing tooling.

Key Features

• Extra heavy-duty duty rating with a spring rate of 2,134 pounds per inch
• Maximum deflection load of 1,865 pounds at 0.87 inches deflection
• Trapezoidal wire cross-section in chromium alloy steel for extended cycle life
• Yellow color coding per ISO 10243 and NAAMS extra heavy-duty classification
• Meets NAAMS, ISO 10243, and ISO 9001:2015 registered standards
• Free length of 3 inches with a compressed length at maximum load of 0.87 inches

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for standard tooling pockets with a 1.5-inch hole diameter and a 0.75-inch rod diameter in stamping dies and industrial press assemblies.

Installation Notes

Installation is typically performed by tooling technicians or millwrights during die build or scheduled die maintenance. Before servicing, de-energize and lock out the press per applicable OSHA lockout/tagout procedures. Seat the spring fully into the die pocket and verify the guide rod diameter and pocket bore match the spring specifications before cycling. Do not compress the spring beyond the rated maximum deflection of 0.87 inches during setup or operation.
