Gibraltar DCIB20-127 Die Spring Extra Heavy-duty Yellow

Product Description

The GIBRALTAR DCIB20-127 is an extra heavy-duty die spring designed for high-load tooling and stamping die applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 413 pounds and a spring rate of 309 pounds per inch. The 5-inch free length compresses to a solid height of 1.34 inches at maximum load, providing 1.34 inches of working travel. Color-coded yellow per industry convention to indicate extra heavy-duty duty rating, it is sized at 3/4-inch hole diameter and 3/8-inch rod diameter. This spring is installed by tool and die technicians, maintenance machinists, and industrial equipment technicians in production tooling environments.

The DCIB20-127 is suited for use in stamping dies, punch press tooling, jigs, fixtures, and other industrial machinery where consistent, high-force spring return is required. The chromium alloy steel construction and trapezoidal wire profile support higher load capacity in a compact envelope compared to round-wire springs of equivalent size. Typical applications include automotive tooling, metal fabrication dies, and OEM machine component replacement. This spring ships individually and is also appropriate for bench-stock use in tool rooms and maintenance shops.

Key Features

• Extra heavy-duty rating with a maximum deflection load of 413 pounds
• Trapezoidal wire cross-section increases load capacity relative to round-wire designs
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• Yellow color coding identifies extra heavy-duty duty rating at a glance
• 1.34 inches of maximum deflection with a spring rate of 309 pounds per inch
• Conforms to NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for stamping dies and industrial tooling applications requiring a 3/4-inch hole diameter, 3/8-inch rod diameter, and 5-inch free length extra heavy-duty spring.

Installation Notes

Die spring replacement is performed by tool and die technicians or maintenance machinists. Always de-energize and lockout the press or machine before servicing tooling components. Inspect the mating rod and bore for wear, burrs, or misalignment before installing a replacement spring, as improper guidance accelerates fatigue failure. Consult the tooling design drawings to confirm free length, hole diameter, rod diameter, and load requirements before substituting springs.
