Gibraltar DCIL25-102 Die Spring 4 Inch Light-duty Green

Product Description

The GIBRALTAR DCIL25-102 is a light-duty die spring engineered for precision tooling, stamping dies, and industrial press applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 118 pounds per inch and a maximum deflection load of 248 pounds. The free length is 4 inches, with a 1 inch hole diameter and a 1/2 inch rod diameter. The green color coding follows the ISO 10243 standard for light-duty classification, making identification straightforward during setup and replacement. This spring is suited for tool and die makers, press maintenance technicians, and industrial maintenance professionals who require consistent, repeatable spring performance in high-cycle die applications.

This die spring is appropriate for use in stamping dies, molds, and fixture assemblies where controlled compression force and reliable return stroke are required. It installs on a guide rod of 1/2 inch diameter inside a 1 inch bore. With a maximum deflection of 2.11 inches and a travel-to-solid measurement of approximately 2.09 inches, it fits applications requiring moderate travel within a compact 4 inch free length envelope. Typical environments include automotive tooling, metal fabrication shops, and general industrial press operations.

Key Features

• Trapezoidal wire cross-section provides higher load capacity per unit length compared to round wire designs
• Chromium alloy steel construction for durability in high-cycle compression applications
• Green color coding denotes light-duty classification per ISO 10243
• Spring rate of 118 pounds per inch for predictable, linear force delivery
• Maximum deflection load of 248 pounds with 2.11 inches of maximum deflection
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement die spring for light-duty stamping dies, molds, and industrial fixtures requiring a 1 inch hole diameter, 1/2 inch rod diameter, and 4 inch free length with green light-duty rating.

Installation Notes

Installation is typically performed by tool and die makers or industrial maintenance technicians during die setup or planned maintenance. Ensure the press or tooling assembly is fully de-energized and mechanically locked out before removing or installing springs. The guide rod should be clean and free of burrs to prevent uneven loading or premature wear. Do not compress the spring beyond its rated maximum deflection of 2.11 inches, as operating at or near solid height accelerates fatigue failure.
