Gibraltar DCIM16-25 Die Spring 1 Inch Blue Medium-duty

Product Description

The GIBRALTAR DCIM16-25 is a medium-duty die spring designed for use in tooling, stamping dies, and industrial press applications. It features a trapezoidal wire cross-section wound from chromium alloy steel, which delivers higher load capacity and longer service life compared to standard round-wire springs of the same envelope size. The hole diameter is 0.625 inches, the rod diameter is 0.344 inches, and the free length is 1 inch. Maximum deflection load is 145 pounds at 0.460 inches of travel. The spring rate is 318 pounds per inch. This part is installed by tool and die makers, maintenance machinists, and industrial equipment technicians.

This die spring is suited for medium-duty cycling loads in stamping dies, molds, fixtures, and industrial machinery where consistent force and repeatable travel are required. The blue color coding identifies the medium-duty load class per standard die spring classification systems. The compressed length at maximum load is 0.460 inches, and maximum travel to solid is 0.472 inches. It is appropriate for applications where space is limited and a compact 1-inch free-length spring is specified.

Key Features

• Trapezoidal wire cross-section for higher load density versus round-wire springs of equivalent size
• Chromium alloy steel construction for durability under cyclic loading
• Blue color code identifies medium-duty load class per NAAMS and ISO 10243 standards
• Spring rate of 318 pounds per inch for predictable, linear force output
• Maximum deflection load of 145 pounds at 0.460 inches of travel
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as a standard replacement die spring for medium-duty tooling and stamping die applications requiring a 5/8-inch hole diameter, 11/32-inch rod diameter, and 1-inch free length per NAAMS and ISO 10243 specifications.

Installation Notes

Die springs should be installed by qualified tooling or maintenance personnel with the press or machine de-energized and all stored energy released before service. Ensure the mating hole and rod dimensions match the spring specifications before installation. Do not exceed the rated maximum deflection to avoid permanent set or premature failure. Consult applicable machinery safety standards and facility lockout/tagout procedures before any tooling work.
