Dayton Lamina 9-0806-26 Die Spring 1.5 in Heavy-duty Red

Product Description

The DAYTON LAMINA 9-0806-26 is a heavy-duty die spring designed for use in metal stamping dies, molds, and tooling fixtures. It features a 0.5-inch hole diameter and a 9/32-inch rod diameter, with a free length of 1.5 inches. Constructed from chromium-vanadium steel, this spring delivers a maximum deflection load of 70 pounds at 0.45 inches of travel. The red color coding identifies it as a heavy-duty load class per ISO 10243 standards. It weighs 0.022 pounds and suits high-cycle tooling environments where consistent spring force is critical.

This die spring is used in metal stamping, progressive die, and injection mold tooling where controlled return force and repeatable deflection are required. It fits standard die sets as a stripper spring, knockout spring, or pressure pad spring. The 30 percent maximum operating deflection rating supports long service life in high-cycle press applications. Tool and die makers, mold makers, and maintenance technicians working in production manufacturing environments typically install this component.

Key Features

• Heavy-duty load class with a maximum deflection load of 70 pounds
• Chromium-vanadium steel construction for high fatigue resistance in production tooling
• 0.45-inch maximum deflection with 0.69-inch travel to solid
• Red color coding for quick load-class identification per ISO 10243
• D-shaped wire cross-section for improved space efficiency in die sets
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as a standard replacement or original-fit die spring for heavy-duty stamping dies, progressive dies, and injection molds requiring a 0.5-inch hole diameter and 9/32-inch rod diameter with a 1.5-inch free length.

Installation Notes

Tool and die makers or maintenance technicians should de-energize and lockout all press equipment before servicing die springs. Verify that the bore and rod dimensions of the die set match the spring specifications before installation to avoid side loading. Do not compress the spring beyond the rated maximum deflection or travel-to-solid value, as this accelerates fatigue failure and can damage tooling. Inspect springs at scheduled maintenance intervals and replace in matched sets when wear or set is observed.
