Gibraltar DCIM20-102 Die Spring 3/4 in Medium-duty Blue

Product Description

The GIBRALTAR DCIM20-102 is a medium-duty die spring designed for use in stamping dies, molds, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers consistent spring force and fatigue resistance under repeated compression cycles. The spring has a 3/4-inch hole diameter, a 3/8-inch rod diameter, and a 4-inch free length. At maximum deflection of 1.69 inches, it produces a load of 187.00 pounds. The blue color coding indicates medium-duty classification, making identification quick during setup and maintenance.

This die spring is suited for use in hydraulic and mechanical press tooling, injection molds, and fixture clamping systems across manufacturing and industrial maintenance environments. It is installed on guide rods or posts within die sets and is typically handled by tool and die makers, maintenance machinists, or industrial MRO technicians. The 4-inch free length and 3/8-inch rod fit make it a common size for medium-stroke tooling applications where controlled return force is required.

Key Features

• Chromium alloy steel construction for high fatigue life under repeated cycling
• Trapezoidal wire shape provides higher load capacity relative to round-wire springs of the same envelope
• Blue color coding identifies medium-duty rating for fast visual selection
• Maximum deflection load of 187.00 pounds at 1.69 inches of travel
• Spring rate of 111.0 pounds per inch for predictable, linear force response
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement or standard die spring for industrial tooling applications requiring a 3/4-inch hole diameter, 3/8-inch rod diameter, and 4-inch free length medium-duty spring conforming to NAAMS and ISO 10243 specifications.

Installation Notes

Die springs are installed by tool and die makers or industrial maintenance technicians as part of die set assembly or tooling repair. Always ensure the guide rod diameter matches the rod diameter specification before installation to prevent buckling or binding under load. Power down and de-energize all press equipment before accessing die components. Do not compress the spring beyond its rated maximum deflection of 1.69 inches during setup or operation.
