Dayton Lamina 9-0812-26 Die Spring Red Heavy-duty

Product Description

The DAYTON LAMINA 9-0812-26 is a heavy-duty die spring designed for use in stamping dies, molds, and industrial tooling applications. It features a 0.5-inch hole diameter and a 9/32-inch rod diameter, with a 3-inch free length. Built from chromium-vanadium steel, this spring delivers a maximum deflection load of 69 pounds at 0.9 inches of maximum deflection. The D-shaped wire profile and red color coding identify it as a heavy-duty grade per ISO 10243 standards. Tooling engineers and die maintenance technicians specify this spring for reliable, repeatable force in high-cycle press tooling.

This die spring is suited for stamping, forming, and die-casting applications in both automotive and general industrial tooling. The red color designation indicates heavy-duty load class, making it appropriate for applications requiring higher spring force within a compact envelope. It is commonly installed in stripper plates, pressure pads, and guided die sets where consistent spring force and dimensional accuracy are critical.

Key Features

• Heavy-duty load rating with 69-pound maximum deflection load
• Chromium-vanadium steel construction for high-cycle durability
• D-shaped wire profile for stable seating and consistent force output
• 30 percent maximum operating deflection with 1.47-inch travel to solid load
• Red color coding per ISO 10243 heavy-duty classification
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an ISO 10243-compliant heavy-duty die spring for use in stamping dies, molds, and industrial tooling wherever a 0.5-inch hole diameter and 9/32-inch rod diameter mounting configuration is required.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance technicians. Always relieve press tonnage and lock out the press before servicing tooling. Inspect the spring seat and guide rod for wear or misalignment before installation, as improper seating can cause premature fatigue. Do not compress the spring beyond the rated maximum operating deflection during service.
