Gibraltar DCIB20-64 Extra Heavy-duty Die Spring Yellow

Product Description

The GIBRALTAR DCIB20-64 is an extra heavy-duty die spring engineered for high-load tooling and stamping applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 461 pounds and a spring rate of 655 pounds per inch. The 0.75-inch hole diameter and 0.375-inch rod diameter allow direct mounting on standard die guide rods. With a free length of 2.5 inches and a maximum deflection of 0.7 inches, this spring is sized for compact die sets where stroke and load capacity are critical. It is installed by toolmakers, die maintenance technicians, and precision machine builders.

This spring is suited for metal stamping dies, punch presses, injection mold tooling, and industrial fixture applications requiring consistent, repeatable force under cyclic compression. The yellow color coding indicates extra heavy-duty load class per ISO 10243 international standards, making it straightforward to identify and sort in multi-spring die assemblies. It is appropriate for both OEM tooling builds and aftermarket replacement in stamping and forming operations.

Key Features

• Extra heavy-duty load rating: 461 pounds maximum deflection load
• Spring rate of 655 pounds per inch for predictable, linear force output
• Trapezoidal wire shape maximizes material contact and load capacity within a compact envelope
• Chromium alloy steel construction for durability under high-cycle fatigue conditions
• Yellow color coding per ISO 10243 for quick visual identification of duty class
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement or direct-fit component for extra heavy-duty die spring applications requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 2.5-inch free length per ISO 10243 and NAAMS specifications.

Installation Notes

Die springs of this type are installed by toolmakers or die maintenance technicians as part of stamping die assemblies or industrial fixtures. Always de-energize and fully de-stroke the press or machine before replacing springs. Inspect the guide rod for wear or scoring before seating the new spring, as rod surface condition directly affects spring service life. Follow applicable OSHA machine guarding and lockout/tagout procedures during any tooling changeout.
