Gibraltar DCIL20-89 Light Duty Die Spring Green

Product Description

The GIBRALTAR DCIL20-89 is a light-duty die spring designed for use in tooling, stamping dies, and press applications where consistent, repeatable spring force is required. It features a trapezoidal wire cross-section that provides higher load capacity per unit length compared to standard round-wire springs. With a free length of 3.5 inches, a 0.75-inch hole diameter, and a 0.375-inch rod diameter, this spring is sized for common die set configurations. It carries a maximum deflection load of 139 pounds and allows up to 1.86 inches of maximum deflection. Manufactured from chromium alloy steel, the green color coding identifies it as a light-duty rating per industry convention.

This die spring is suited for use in metal stamping dies, injection mold tooling, jigs, fixtures, and other precision press or machine tool applications. The light-duty rating makes it appropriate for applications requiring moderate, controlled force with frequent cycling. Toolmakers, die setters, and machine builders typically specify this spring for stripper plates, lifters, and return mechanisms in both prototype and production tooling environments.

Key Features

• Trapezoidal wire shape provides greater load capacity and longer fatigue life compared to round-wire alternatives
• Light-duty green color coding follows NAAMS and ISO 10243 standard identification conventions
• Maximum deflection load of 139 pounds with up to 1.86 inches of travel
• Chromium alloy steel construction for durability in cyclic loading applications
• Spring rate of 75 pounds per inch for predictable, linear force output
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as a standard-profile replacement or original-equipment die spring for light-duty tooling and stamping die applications requiring a 0.75-inch hole diameter and 0.375-inch rod diameter with a 3.5-inch free length.

Installation Notes

Installation is typically performed by toolmakers or die setters during die assembly or maintenance. Always depressurize and lock out the press before removing or installing die springs. Ensure the mating rod and hole diameters are within tolerance to prevent lateral loading, which can cause premature fatigue failure. Do not compress the spring beyond its rated maximum deflection during operation.
