Dayton Lamina 9-0848-26 Die Spring 12 Inch Red Heavy-duty

Product Description

The DAYTON LAMINA 9-0848-26 is a heavy-duty die spring engineered for precision tooling and stamping die applications. Built from chromium-vanadium steel, it features a D-shaped wire cross-section that increases load capacity and resistance to fatigue compared to round-wire designs. The spring measures 12 inches in free length, accepts a 1/2-inch hole diameter, and is sized for a 9/32-inch rod diameter. It delivers a maximum deflection load of 64 pounds at 3.6 inches of maximum deflection, with a travel-to-solid load of 5.71 inches. The red color coding identifies it as a heavy-duty rating per ISO 10243 standards. Die maintenance technicians and tool-and-die professionals handle installation in production tooling environments.

This spring is suited for use in stamping dies, punch press tooling, injection molds, and similar high-cycle industrial applications where consistent spring force and long fatigue life are required. The heavy-duty designation targets applications demanding higher load capacity within a given space envelope. Its 30 percent maximum operating deflection rating helps prevent overcompression during production runs, extending service intervals and reducing unplanned downtime in manufacturing tooling.

Key Features

• Chromium-vanadium steel construction for high fatigue resistance in heavy-cycle tooling
• D-shaped wire profile increases load-bearing capacity over equivalent round-wire springs
• Red color coding identifies heavy-duty duty rating per ISO 10243 International Standard
• Maximum deflection load of 64 pounds at 3.6 inches of travel
• 30 percent maximum operating deflection rating guards against overcompression
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an ISO 10243-compliant heavy-duty die spring for use in standard stamping die sets, punch press tooling, and industrial mold assemblies requiring a 1/2-inch hole diameter and 9/32-inch rod diameter with a 12-inch free length.

Installation Notes

Installation is typically performed by tool-and-die technicians during die setup or maintenance. Ensure the press or tooling is fully de-energized and at rest before removing or replacing die springs. Do not exceed the 30 percent maximum operating deflection during normal production cycles to avoid premature failure or coil bind. Inspect the rod and bore for wear or misalignment before seating the replacement spring, as side loading will reduce fatigue life.
