Gibraltar DCIL25-140 Die Spring 5.5 in Light-duty Green

Product Description

The GIBRALTAR DCIL25-140 is a light-duty die spring designed for use in stamping dies, punch presses, molds, and similar tooling applications. It features a trapezoidal wire cross-section wound from chromium alloy steel, which provides consistent force output and resistance to fatigue under repeated compression cycles. The spring has a 1-inch hole diameter, a 0.5-inch rod diameter, and a free length of 5.5 inches. Maximum deflection load is 234 pounds, with a maximum deflection of 2.81 inches. This part is installed by toolmakers, die setters, and maintenance technicians working in metal fabrication and production tooling environments.

This spring is suited for light-duty tooling applications in stamping, forming, and injection mold operations. Its green color coding follows the ISO 10243 international standard for die spring duty classification, making it straightforward to identify and cross-reference on the shop floor or in a maintenance inventory. The 5.5-inch free length and 0.5-inch rod diameter make it a common fit for standard die sets requiring a controlled return force with moderate stroke.

Key Features

• Trapezoidal wire cross-section provides higher load capacity and longer fatigue life compared to round wire springs of equivalent size
• Chromium alloy steel construction for durability under cyclic compressive loads
• Green color code indicates light-duty classification per ISO 10243 and NAAMS standards
• Maximum deflection load of 234 pounds at 2.81 inches of travel
• Spring rate of 83 pounds per inch for predictable, linear force output
• Meets NAAMS, ISO 10243, and ISO 9001:2015 registered standards

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for light-duty stamping dies, punch presses, and mold tooling requiring a 1-inch hole diameter and 0.5-inch rod diameter with a 5.5-inch free length.

Installation Notes

Die springs should be installed by qualified toolmakers or maintenance technicians familiar with press and die safety procedures. Always de-energize and lockout the press before removing or installing springs. Inspect the mating rod and guide bore for wear or damage before installation, as misalignment accelerates fatigue failure. Do not exceed the rated maximum deflection of 2.81 inches during operation.
