Dayton Lamina 9-1620-26 Die Spring 5 in Red Heavy-duty

Product Description

The DAYTON LAMINA 9-1620-26 is a heavy-duty die spring designed for use in metal stamping dies, punch presses, and tooling assemblies. Built from chromium-vanadium steel with a D-shaped wire profile, it delivers high load capacity in a compact form. The spring features a 1 inch hole diameter, a 1/2 inch rod diameter, and a 5 inch free length. At maximum deflection of 1.5 inches, it produces a load of 497 pounds. The red color coding identifies it as a heavy-duty spring per ISO 10243 standards. Licensed HVAC, tooling, and die maintenance professionals specify this part for precision tooling applications requiring consistent, repeatable spring performance.

This die spring is suited for industrial tooling environments including stamping dies, injection molds, and material handling fixtures. Its heavy-duty duty rating makes it appropriate for high-cycle applications where consistent force and deflection characteristics are critical. The ISO 10243 color and size coding allows direct interchangeability across tooling systems that follow international or NAAMS dimensional standards. Installation is typical in manufacturing and tool-and-die shops by toolmakers and maintenance machinists.

Key Features

• Heavy-duty duty rating with a maximum deflection load of 497 pounds
• Chromium-vanadium steel construction for high-cycle fatigue resistance
• D-shaped wire profile for increased load capacity per unit length
• Red color coding per ISO 10243 for easy duty-rating identification
• Maximum operating deflection of 30 percent of free length (1.5 inches)
• Travel to solid load of 1.77 inches provides a defined compression limit

Compatibility

Designed as an ISO 10243-compliant replacement die spring for heavy-duty tooling applications requiring a 1 inch hole diameter, 1/2 inch rod diameter, and 5 inch free length. Compatible with systems built to NAAMS (North American Automotive Metric Standard) specifications.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance personnel with the press fully de-energized and locked out per OSHA lockout/tagout procedures. Ensure the mating rod and hole diameters in the die set match the spring specifications before installation. Do not compress the spring beyond its travel-to-solid value of 1.77 inches, as doing so may cause permanent set or component damage. Inspect springs regularly for signs of fatigue, cracking, or loss of free length during scheduled die maintenance intervals.
