Gibraltar DCIH40-114 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH40-114 is a heavy-duty die spring rated for demanding industrial tooling and stamping applications. Built from chromium alloy steel with a trapezoidal wire profile, it delivers a spring rate of 889 pounds per inch and a maximum deflection load of 1,485 pounds. The free length is 4.5 inches, with a maximum deflection of 1.67 inches before reaching solid. Color-coded red to indicate heavy-duty load classification, this spring is used by toolmakers, press technicians, and die maintenance professionals who need reliable, repeatable spring performance under high cyclic loads.

This die spring is suited for metal stamping dies, punch press tooling, plastic injection molds, and other precision tooling fixtures where consistent spring force and long service life are required. The 1.5-inch hole diameter accommodates a 0.75-inch rod diameter, making it a direct fit for standard die set configurations. It conforms to NAAMS and ISO 10243 dimensional standards, making it a straightforward replacement in tooling designed to those specs.

Key Features

• Heavy-duty load rating with a maximum deflection load of 1,485 pounds (6,608.25 N)
• Spring rate of 889 pounds per inch for predictable, linear force output
• Trapezoidal wire cross-section for higher load capacity versus round wire designs
• Chromium alloy steel construction for fatigue resistance under repeated cycling
• Red color coding follows ISO 10243 and NAAMS load-class identification standards
• Conforms to NAAMS, ISO 10243, and is manufactured under ISO 9001:2015 registered quality systems

Compatibility

Designed as a NAAMS- and ISO 10243-compliant replacement die spring for tooling and die sets requiring a 1.5-inch hole diameter, 0.75-inch rod diameter, and 4.5-inch free length in the heavy-duty red load class.

Installation Notes

Die spring replacement is typically performed by toolmakers or die maintenance technicians during scheduled tooling maintenance or after spring fatigue failure. Always relieve all press load and lock out the press before disassembling the die set. Inspect the rod and guide bore for wear or scoring before installing the new spring, as surface damage accelerates fatigue. Do not compress the spring beyond the rated maximum deflection of 1.67 inches, as exceeding this value will result in coil bind and rapid failure.
