Dayton Lamina 9-2412-26 Die Spring 3 in Heavy-duty Red

Product Description

The DAYTON LAMINA 9-2412-26 is a heavy-duty die spring engineered for use in stamping dies, press tooling, and industrial mold assemblies. It features a D-shaped wire cross-section and is manufactured from chromium-vanadium steel for high fatigue resistance under repeated compression cycles. The spring has a 3-inch free length, a 1.5-inch hole diameter, and a 0.75-inch rod diameter, with a maximum deflection load of 1122 pounds at 0.9 inches of travel. Color-coded red to indicate heavy-duty load rating per ISO 10243 standards. This component is installed by tooling engineers and die maintenance technicians in production press environments.

This spring is suited for heavy-duty stamping die applications in both automotive and general industrial settings. It performs in high-cycle tooling where consistent spring force and dimensional precision are critical. The D-shaped wire profile provides a stable seating surface and maximizes the load capacity within standard die spring bore dimensions. Maximum operating deflection is rated at 30 percent of free length, making it appropriate for applications requiring controlled, repeatable spring travel.

Key Features

• Heavy-duty load rating with 1122 lb maximum deflection load
• Chromium-vanadium steel construction for fatigue resistance in high-cycle applications
• D-shaped wire profile for stable seating and consistent force output
• 3-inch free length with 0.9-inch maximum deflection travel
• Red color coding per ISO 10243 heavy-duty classification
• Compliant with ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for heavy-duty stamping die assemblies requiring a 1.5-inch bore diameter and 0.75-inch rod diameter with a 3-inch free length per ISO 10243 international standards.

Installation Notes

Die springs are installed and serviced by qualified tooling technicians or die maintenance personnel. Always de-energize and lock out the press before removing or replacing springs in a die assembly. Inspect bore and rod mating surfaces for wear or misalignment before installation, as off-axis loading can reduce spring service life. Do not compress beyond the rated maximum operating deflection of 30 percent of free length during normal operation.
