Gibraltar DCIM40-102 Die Spring 4 in Blue Medium-duty

Product Description

The GIBRALTAR DCIM40-102 is a medium-duty die spring engineered for use in stamping dies, press tooling, and industrial machinery applications that demand consistent return force and long cycle life. Built from chromium alloy steel with a trapezoidal wire profile, this spring delivers a maximum deflection load of 690 pounds at 1.6 inches of travel. It measures 4 inches in free length with a 1.5 inches hole diameter and a 0.75 inches rod diameter, making it a direct-fit component for standard die sets using color-coded ISO-style spring arrangements. Licensed HVAC, plumbing, and industrial maintenance technicians working on press or tooling applications will recognize the blue color designation as the medium-duty classification within the ISO 10243 standard family.

This die spring is suited for medium-load tooling applications in automotive, metal fabrication, and general manufacturing environments. It is designed for installations where consistent spring rate and predictable travel-to-solid behavior are critical to part quality and die longevity. The spring rate of 431 pounds per inch supports repeatable performance across high-cycle press operations. Sold individually, it is appropriate for single-position replacement or matched-set builds in standard die shoe configurations.

Key Features

• Chromium alloy steel construction with trapezoidal wire cross-section for high load capacity in a compact envelope
• Medium-duty blue color coding per ISO 10243 and NAAMS standards for easy identification in multi-spring die layouts
• 690 pound maximum deflection load with a spring rate of 431 pounds per inch
• 1.6 inches maximum deflection with 1.5906 inches travel to solid
• Meets NAAMS, ISO 10243, and ISO 9001:2015 registered quality standards
• 1.5 inches hole diameter and 0.75 inches rod diameter for standard die post fitment

Compatibility

Designed as an OEM-style replacement or new-build component for medium-duty die sets and press tooling that use ISO 10243 or NAAMS standard color-coded die springs with a 1.5 inches hole diameter and 0.75 inches rod diameter.

Installation Notes

Die spring replacement and installation should be performed by qualified tool and die technicians or maintenance personnel familiar with press tooling safety procedures. Always de-energize and lock out the press before accessing die components. Do not compress the spring beyond its rated maximum deflection of 1.6 inches, as exceeding travel-to-solid limits can cause premature failure or die damage. Inspect mating rod and pocket surfaces for wear or misalignment before installing a new spring.
