Gibraltar DCIH25-89 Heavy-duty Die Spring Red 3.5 in

Product Description

The GIBRALTAR DCIH25-89 is a heavy-duty die spring designed for use in stamping dies, press tooling, and industrial machinery where consistent, reliable spring force is required. Wound from chromium alloy steel with a trapezoidal wire profile, this spring delivers a maximum deflection load of 612 pounds over a maximum deflection of 1.19 inches. The free length is 3.5 inches, with a hole diameter of 1 inch and a rod diameter of 0.5 inch. The red color coding identifies it as a heavy-duty rated spring per standard industry classification. Installation is performed by tool and die makers, maintenance machinists, and industrial technicians.

This die spring is suited for high-load stamping and forming applications in automotive, metalworking, and general industrial environments. The trapezoidal wire cross-section maximizes the active coil surface area, supporting higher load capacity and longer fatigue life compared to round-wire springs of equivalent envelope dimensions. It conforms to NAAMS and ISO 10243 dimensional standards, making it a compatible replacement in tooling designed to those specifications. Sold individually.

Key Features

• Heavy-duty load rating with 612 pounds maximum deflection load
• Trapezoidal wire shape for increased load density and fatigue resistance
• Chromium alloy steel construction for durability under cyclic loading
• Red color coding identifies heavy-duty duty rating per standard die spring classification
• Conforms to NAAMS and ISO 10243 international die spring standards
• Spring rate of 514 pounds per inch for predictable force-deflection behavior

Compatibility

Designed as a replacement or new-installation die spring for tooling built to NAAMS and ISO 10243 standards, with a 1 inch hole diameter and 0.5 inch rod diameter envelope. Confirm free length and duty rating against existing tooling specifications before installation.

Installation Notes

Die springs are installed and serviced by qualified tool and die technicians or industrial maintenance personnel. Always de-energize and lock out the press or machine before accessing the die set. Verify that the spring seat and guide rod are free of burrs or damage before seating the spring. Do not exceed the rated maximum deflection of 1.19 inches, as operating beyond this point can result in coil contact and premature failure.
