Gibraltar DCIL10-51 Die Spring 3/8 in Light-duty Green

Product Description

The GIBRALTAR DCIL10-51 is a light-duty die spring designed for use in tooling, stamping dies, and precision machinery applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force and reliable cycle life under repetitive compression loads. It features a 3/8 inch hole diameter, a 3/16 inch rod diameter, and a 2 inch free length. Maximum deflection load is 39.00 pounds at 1.09 inches of travel. The green color coding identifies its light-duty rating, following industry-standard color conventions for quick identification during tool setup and maintenance.

This die spring is suited for light-duty press tooling, injection mold assemblies, and precision fixture applications in manufacturing and industrial environments. Its compact 2 inch free length makes it appropriate for shallow die sets and space-constrained tooling configurations. Toolmakers, die setters, and maintenance technicians working with stamping or molding equipment are the primary installers. The spring conforms to NAAMS and ISO 10243 standards, making it a direct fit for internationally standardized die spring pocket dimensions.

Key Features

• Chromium alloy steel construction with trapezoidal wire cross-section for consistent load performance
• Green color coding identifies light-duty rating per standard die spring classification
• 3/8 inch hole diameter and 3/16 inch rod diameter for precise die pocket and guide rod fitment
• Maximum deflection load of 39.00 pounds with 1.09 inches maximum deflection
• Spring rate of 36.00 pounds per inch for predictable, linear force output
• Compliant with NAAMS, ISO 10243, and manufactured under ISO 9001:2015 registered quality standards

Compatibility

Designed as a replacement light-duty die spring conforming to NAAMS and ISO 10243 dimensional standards, compatible with tooling die sets and fixtures engineered to accept a 3/8 inch hole diameter, 3/16 inch rod diameter, and 2 inch free length spring pocket.

Installation Notes

Die spring installation and replacement should be performed by qualified toolmakers or die maintenance technicians with the press or machine fully de-energized and locked out per OSHA lockout/tagout procedures. Inspect the die pocket and guide rod for wear or damage before installing the new spring. Do not compress the spring beyond its rated maximum deflection of 1.09 inches, as over-compression can cause permanent set or premature failure. Always verify the replacement spring color code and free length match the original tooling specification before installation.
