Dayton Lamina 9-3214-36 Die Spring Extra Heavy-duty Yellow

Product Description

The DAYTON LAMINA 9-3214-36 is an extra heavy-duty die spring designed for use in stamping dies, press tooling, and industrial mold applications. Built from chromium-vanadium steel, it delivers a maximum deflection load of 2374 pounds and a maximum deflection of 0.88 inches at 25 percent of free length. The spring features a D-shaped wire cross-section, which increases contact surface area and helps resist rotation under load. With a free length of 3.5 inches, a 2-inch hole diameter, and a 1-inch rod diameter, this spring is dimensioned for direct drop-in use in standard die sets. Installation is handled by toolmakers, die setters, and maintenance technicians in manufacturing and fabrication environments.

This die spring is suited for high-cycle stamping, forming, stripping, and lifting operations in press tooling. Its extra heavy-duty rating makes it appropriate for applications where standard or heavy-duty springs would fatigue prematurely under high loads or frequent cycling. The yellow color coding follows ISO 10243 conventions, allowing quick visual identification of duty rating in the toolroom or on the press floor. Compatible with tooling designed around ISO 10243 outer diameter and rod diameter standards.

Key Features

• Extra heavy-duty duty rating for high-load, high-cycle die and press tooling applications
• Chromium-vanadium steel construction for fatigue resistance and long service life
• D-shaped wire profile increases bearing surface and reduces spring rotation
• Maximum deflection load of 2374 pounds with 0.88 inches of available travel
• Yellow color coding per ISO 10243 for fast visual duty-rating identification
• Meets ISO 10243, ISO 9001:2015, and NAAMS dimensional and quality standards

Compatibility

Dimensioned to ISO 10243 international standards with a 2-inch hole diameter and 1-inch rod diameter, making it a direct fit for tooling built to those specifications. Also conforms to NAAMS (North American Automotive Metric Standard) requirements for die spring applications.

Installation Notes

Die springs of this type are installed by qualified toolmakers or die maintenance technicians. Always de-energize and lock out the press before servicing tooling. Ensure the spring seat and rod are free of burrs or debris that could damage the spring ends or cause misalignment. Do not compress this spring beyond the rated maximum deflection of 0.88 inches, as exceeding rated travel will shorten service life and may cause premature failure.
