Dayton Lamina 9-1608-36 Die Spring Extra Heavy-duty

Product Description

The DAYTON LAMINA 9-1608-36 is an extra heavy-duty die spring engineered for precision tooling and stamping applications. It features a 1 inch hole diameter, a 1/2 inch rod diameter, and a 2 inch free length. Constructed from chromium-vanadium steel, this spring delivers a maximum deflection load of 567 pounds at a maximum deflection of 0.5 inches. The D-shaped wire profile and yellow color coding comply with ISO 10243 standards for quick identification of duty rating. It is installed by tool-and-die makers, press technicians, and maintenance personnel working with metal stamping and forming equipment.

This die spring is suited for use in metal stamping dies, progressive dies, and punch press tooling where consistent, high-force spring return is required. The extra heavy-duty rating makes it appropriate for high-cycle industrial press operations in both automotive and general manufacturing environments. It is sold individually and is designed as a direct replacement or spare for tooling that specifies a 1 inch hole, 1/2 inch rod, 2 inch free length die spring in the extra heavy-duty yellow class.

Key Features

• Extra heavy-duty duty rating with 567 pound maximum deflection load
• 1 inch hole diameter and 1/2 inch rod diameter for precise die fitment
• 2 inch free length with 0.5 inch maximum operating deflection
• D-shaped wire cross-section for stable seating in die pockets
• Chromium-vanadium steel construction for fatigue resistance in high-cycle applications
• Yellow color coding per ISO 10243 for fast duty-class identification

Compatibility

Designed as an ISO 10243 standard-compliant replacement die spring for tooling applications requiring a 1 inch hole diameter, 1/2 inch rod diameter, 2 inch free length, extra heavy-duty class spring. Also conforms to NAAMS (North American Automotive Metric Standard) specifications.

Installation Notes

Die springs are installed by qualified tool-and-die technicians or press maintenance personnel. Always de-energize and lock out the press before accessing the die set. Inspect the spring pocket and guide rod for wear or damage before installing a replacement spring. Do not compress the spring beyond its rated maximum deflection, as exceeding the travel-to-solid dimension can cause permanent set or premature failure.
