Gibraltar DCIM20-89 Die Spring Medium Duty Blue

Product Description

The GIBRALTAR DCIM20-89 is a medium-duty die spring engineered for precision tooling and stamping applications. It features a trapezoidal wire cross-section wound from chromium alloy steel, which delivers consistent force and extended cycle life compared to standard round-wire springs. The spring has a 0.75-inch hole diameter, a 0.375-inch rod diameter, and a 3.5-inch free length. At maximum deflection of 1.46 inches, it handles a peak load of 184 pounds. Identified by its blue color coding per ISO 10243 standards, this spring is suited for installation by toolmakers, die setters, and maintenance technicians working with progressive or stamping dies.

This die spring is designed for use in metal stamping dies, punch presses, and industrial tooling fixtures where controlled, repeatable spring force is required. The medium-duty rating makes it appropriate for applications requiring moderate load capacity without the space demands of heavy-duty configurations. It is commonly used in both OEM die assemblies and aftermarket tooling replacement scenarios across automotive, aerospace, and general manufacturing environments. The blue color designation aligns with NAAMS and ISO 10243 load-class coding for medium duty.

Key Features

• Trapezoidal wire shape provides higher load capacity and longer fatigue life than round-wire alternatives
• Chromium alloy steel construction for durability under repeated compression cycles
• Blue color coding per ISO 10243 and NAAMS standards for easy load-class identification
• Maximum deflection load of 184 pounds at 1.46 inches of travel
• Spring rate of 126 pounds per inch for predictable, linear force response
• Meets NAAMS, ISO 10243, and ISO 9001:2015 registered quality standards

Compatibility

Designed as an ISO 10243 and NAAMS compliant replacement die spring for medium-duty tooling applications with a 0.75-inch hole diameter and 0.375-inch rod diameter. Verify free length and duty rating against the existing spring specification before installation.

Installation Notes

Die springs are typically installed and replaced by toolmakers or die maintenance technicians. Always relieve all press load and lockout the press before accessing the die assembly. Confirm the rod diameter, hole diameter, and free length match the die pocket specifications before seating the spring. Do not exceed the rated maximum deflection to avoid permanent set or premature failure.
