Gibraltar DCIL20-140 Die Spring Light-duty Green 5.5in

Product Description

The GIBRALTAR DCIL20-140 is a light-duty die spring designed for use in stamping dies, press tooling, and industrial fixtures requiring controlled compression force. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 149.00 pounds (663.05 N) across a maximum deflection of 3.0500 inches. The spring has a free length of 5.5 inches, a 0.75-inch hole diameter, and a 0.375-inch rod diameter. The green color coding identifies it as a light-duty rating per standard die spring classification. This spring is installed and replaced by tool-and-die makers, maintenance technicians, and industrial machine repair professionals.

This die spring is suited for light-duty press tool applications in stamping, forming, and automated assembly equipment. It is used in both original equipment builds and replacement service situations where consistent spring force and reliable cycle life are required. The trapezoidal wire profile maximizes load capacity relative to the coil cross-section, making it a practical choice in space-constrained tooling cavities where a round-wire spring of equivalent diameter would carry less load.

Key Features

• Light-duty rating with 149.00-pound maximum deflection load
• Trapezoidal wire cross-section for higher load density in compact tooling
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• Green color coding for quick visual identification of duty rating
• Spring rate of 49.0 lb/in for predictable, linear force curve
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement die spring for light-duty stamping and press tooling applications requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 5.5-inch free length. Conforms to NAAMS and ISO 10243 dimensional standards, allowing cross-reference with other springs built to those specifications.

Installation Notes

Die spring replacement is performed by qualified tool-and-die or maintenance personnel with the press fully de-energized and all stored energy released before disassembly. Confirm the rod diameter and bore clearance match the replacement spring before installation. Do not compress the spring beyond the rated maximum deflection of 3.0500 inches, as over-compression accelerates fatigue failure. Inspect the mating rod and bore surfaces for wear or burrs that could damage the coil during operation.
