Gibraltar DCIB25-102 Die Spring 4 Inch Extra Heavy-duty Yellow

Product Description

The GIBRALTAR DCIB25-102 is an extra heavy-duty die spring designed for use in stamping dies, injection molds, and industrial press tooling where high compressive force is required in a compact envelope. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 711 pounds and a spring rate of 544 pounds per inch. The yellow color designation indicates its extra heavy-duty duty rating in accordance with NAAMS and ISO 10243 standards. Licensed machinists, tool-and-die makers, and industrial maintenance technicians are the typical installers of this component.

This die spring is suited for high-cycle industrial applications including progressive stamping dies, plastic injection molds, and mechanical press tooling. The 1 inch hole diameter and 0.5 inch rod diameter allow it to seat securely on a guide rod or within a counterbored pocket. With a 4 inch free length and a maximum deflection of 1.31 inches, it is appropriate for applications requiring a stiff, controlled return force across a short stroke. It is sold and packaged individually.

Key Features

• Extra heavy-duty duty rating with a maximum deflection load of 711 pounds (3,163.95 N)
• Trapezoidal wire cross-section provides higher load capacity per unit length compared to round wire
• Chromium alloy steel construction for durability in high-cycle press and die applications
• Spring rate of 544 pounds per inch for consistent, predictable deflection behavior
• Yellow color coding for quick identification of duty rating in multi-spring tooling setups
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement or new-installation die spring for industrial stamping, molding, and press tooling applications requiring a 1 inch hole diameter, 0.5 inch rod diameter, and 4 inch free length in an extra heavy-duty rating.

Installation Notes

Installation is typically performed by tool-and-die makers or industrial maintenance technicians during die build or tooling maintenance. Ensure the guide rod diameter and counterbore dimensions match the spring's rod and hole diameter specifications before seating the spring. De-energize and lock out all press or machine energy sources before servicing any die components. Do not compress this spring beyond its rated maximum deflection of 1.31 inches to avoid permanent set or fatigue failure.
