Gibraltar DCIH40-89 Die Spring 1-1/2in Heavy-duty Red

Product Description

The GIBRALTAR DCIH40-89 is a heavy-duty die spring designed for use in stamping dies, punch presses, and similar metal-forming tooling applications. It features a 1.5-inch hole diameter, a 0.75-inch rod diameter, and a free length of 3.5 inches. The spring is wound from chromium alloy steel with a trapezoidal wire cross-section, which increases the load-bearing surface area compared to round wire. At maximum deflection of 1.19 inches, it delivers a load of 1,342 pounds. The red color coding indicates a heavy-duty load rating per standard die spring classification conventions. This part ships as a single-piece unit.

This die spring is used in industrial tooling environments where high compressive loads and consistent return force are required. Typical applications include stamping dies, injection molds, jigs, and fixtures in manufacturing and fabrication settings. It is installed and serviced by tool and die makers, press technicians, and industrial maintenance personnel. The spring conforms to NAAMS and ISO 10243 standards, making it suitable for both domestic and internationally specified tooling builds.

Key Features

• Heavy-duty load rating with 1,342 pounds maximum deflection load at 1.19 inches of travel
• Trapezoidal wire shape increases contact surface area for improved load capacity over round wire springs
• Chromium alloy steel construction for high fatigue resistance under cyclic compression
• Red color coding per standard die spring load-class identification
• Meets NAAMS, ISO 10243, and ISO 9001:2015 registered standards
• Compact 3.5-inch free length suits a wide range of tooling cavity depths

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for stamping dies and press tooling requiring a 1.5-inch hole diameter and 0.75-inch rod diameter with a 3.5-inch free length in the heavy-duty red load class per NAAMS and ISO 10243 specifications.

Installation Notes

Installation is typically performed by tool and die makers or industrial maintenance technicians during die build or scheduled tooling maintenance. Before servicing any press or die assembly, verify that the machine is fully de-energized, locked out, and blocked against unintended closure. Ensure the rod diameter and hole diameter of the tooling match the spring dimensions before pressing the spring into position. Do not exceed the rated maximum deflection to avoid permanent set or premature fatigue failure.
