Dayton Lamina 9-1014-26 Die Spring Heavy-duty Red

Product Description

The DAYTON LAMINA 9-1014-26 is a heavy-duty die spring designed for use in metal stamping, die sets, and press tooling applications. Built from chromium-vanadium steel, it features a D-shaped wire cross-section that maximizes load capacity within a compact envelope. The spring carries a maximum deflection load of 125 pounds at 1.05 inches of travel, with a travel-to-solid measurement of 1.57 inches. The red color coding follows the ISO 10243 international standard for heavy-duty spring classification, making identification fast during die maintenance and setup. At 0.071 pounds, it is lightweight without sacrificing load performance.

This die spring is suited for use in progressive dies, compound dies, blanking dies, and general press tooling where consistent return force and repeatable deflection are required. It fits a 0.625-inch hole diameter and accepts a 0.344-inch rod diameter, accommodating standard die set rod configurations. The 3.5-inch free length provides adequate stroke for medium-travel applications in both production stamping and short-run tooling environments. Installation is appropriate for tool and die makers and maintenance technicians working with mechanical or hydraulic press equipment.

Key Features

• Heavy-duty load rating with a maximum deflection load of 125 pounds
• Chromium-vanadium steel construction for fatigue resistance under cyclic loading
• D-shaped wire profile maximizes force output relative to envelope size
• Red color coding per ISO 10243 for quick identification in die sets
• Maximum operating deflection of 30 percent of free length
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for heavy-duty die set applications requiring a 0.625-inch hole diameter, 0.344-inch rod diameter, and 3.5-inch free length per ISO 10243 specifications.

Installation Notes

Die springs should be installed by qualified tool and die makers or press maintenance technicians familiar with die set assembly. Always relieve press tonnage and lock out all energy sources before removing or installing die springs. Do not exceed the maximum operating deflection of 30 percent of free length during normal production cycles, as operating beyond this limit accelerates fatigue failure. Inspect springs for cracking, set, or corrosion at each scheduled die maintenance interval.
