Dayton Lamina 9-2424-26 Heavy-duty Die Spring Red

Product Description

The DAYTON LAMINA 9-2424-26 is a heavy-duty die spring designed for use in metal stamping dies, molds, and precision tooling fixtures. It features a 1.5-inch hole diameter, a 0.75-inch rod diameter, and a free length of 6 inches. Manufactured from chromium-vanadium steel, this spring delivers consistent force and fatigue resistance under repeated cycling loads. The D-shaped wire cross-section allows higher load capacity within a compact envelope compared to round-wire designs. The red color coding identifies it as a heavy-duty rated spring per ISO 10243 standards. It weighs 1.12 pounds and is intended for installation by toolmakers, die setters, and precision machining professionals.

This die spring is suited for heavy-duty applications in metal stamping, progressive dies, injection molds, and fixture clamping assemblies. It performs in both horizontal and vertical orientations wherever consistent return force and controlled deflection are required. The spring is appropriate for high-cycle production tooling environments in automotive, aerospace, and general manufacturing settings. A maximum operating deflection of 30 percent of free length keeps the spring within its rated fatigue life under normal production conditions.

Key Features

• Heavy-duty load rating with a maximum deflection load of 1,059 pounds
• Maximum deflection of 1.8 inches at full rated load
• Travel to solid load of 2.18 inches provides controlled bottoming margin
• D-shaped wire cross-section increases load density compared to round-wire springs
• Chromium-vanadium steel construction for high fatigue strength and wear resistance
• Red color coding per ISO 10243 heavy-duty designation for quick field identification
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an OEM-style replacement or direct-fit component for heavy-duty die spring applications requiring a 1.5-inch hole diameter, 0.75-inch rod diameter, and 6-inch free length per ISO 10243 heavy-duty specifications.

Installation Notes

Die springs should be installed by qualified toolmakers or die setters following established press and tooling safety procedures. Always de-energize and lock out the press before servicing any die components. Do not compress the spring beyond its rated maximum operating deflection of 30 percent during normal production cycles, as exceeding this limit reduces fatigue life. Inspect springs periodically for coil cracking, set, or discoloration, and replace any spring showing signs of fatigue before returning the die to service.
