Gibraltar DCIH40-51 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH40-51 is a heavy-duty die spring engineered for use in stamping dies, press tooling, and industrial fixture applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 1404 pounds (6247.80 N) and a spring rate of 2122 pounds per inch. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 2 inch free length. The red color coding indicates its heavy-duty load classification, consistent with ISO 10243 international die spring standards. Tool and die makers, press operators, and industrial maintenance technicians work with this part in production tooling environments.

This die spring is suited for installation in stamping dies, injection mold tooling, jigs, and fixtures that require controlled, repeatable spring force. It accommodates a maximum deflection of 0.6600 inches (16.76 mm) and compresses to a solid length of 0.66 inches under maximum load. The NAAMS and ISO 10243 dimensional standards make it a compatible form-fit-function replacement in tooling designed to those specifications. It is appropriate for both light production and high-cycle industrial press applications where consistent load performance is required.

Key Features

• Heavy-duty load rating with 1404 pounds maximum deflection load
• Trapezoidal wire cross-section provides higher load capacity compared to round wire springs of equivalent size
• Chromium alloy steel construction for durability under cyclic compressive loads
• Red color coding identifies heavy-duty duty rating per ISO 10243 and NAAMS standards
• Spring rate of 2122 pounds per inch for predictable, linear force output
• Conforms to ISO 10243 International Standard and NAAMS dimensional specifications

Compatibility

Designed as an OEM-style replacement or direct substitute for heavy-duty die springs conforming to ISO 10243 and NAAMS dimensional standards with a 1-1/2 inch hole diameter, 3/4 inch rod diameter, and 2 inch free length.

Installation Notes

Installation should be performed by qualified tool and die technicians or industrial maintenance personnel familiar with press tooling. Relieve all press and tooling load before removing or replacing die springs. Inspect the mating rod and bore surfaces for wear or damage prior to installation. Follow applicable tooling engineering drawings and shop safety procedures when working with high-load spring components.
