Dayton Lamina 9-4032-21 Die Spring 8 Inch Medium-duty Blue

Product Description

The DAYTON LAMINA 9-4032-21 is a medium-duty die spring designed for use in stamping dies, punch presses, and other precision tooling applications. It features a 2.5-inch hole diameter, a 1.5-inch rod diameter, and an 8-inch free length, making it suited for applications that require substantial spring force in a large-format bore. Constructed from chromium-vanadium steel, it delivers reliable load performance and fatigue resistance under repeated cycling. The blue color coding identifies it as a medium-duty rating per standard die spring classification. Maximum deflection load is 1,649 pounds at 3 inches of deflection.

This spring is used in metal stamping and forming dies in both production and job-shop environments. It fits standard die sets where a 2.5-inch bore and 1.5-inch guide rod are specified. Typical installation scenarios include stripper plate actuation, blank holder pressure, and component ejection in progressive or compound dies. Toolmakers, die setters, and press maintenance technicians are the primary installers of this component.

Key Features

• Medium-duty rating with blue color coding for quick identification
• Chromium-vanadium steel construction for high fatigue resistance and durability under cyclic loading
• 2.5-inch hole diameter and 1.5-inch rod diameter for standard large-format die set fitment
• Maximum deflection load of 1,649 pounds at 3 inches of travel
• D-shaped wire cross-section for consistent load distribution and spring stability
• Maximum operating deflection of 37.50 percent of free length

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for standard tooling applications requiring a 2.5-inch hole diameter, 1.5-inch rod diameter, and 8-inch free length in medium-duty die sets.

Installation Notes

Installation is performed by toolmakers or die maintenance technicians during die assembly or spring replacement. Always de-energize and lock out the press before servicing any tooling components. Ensure the guide rod and bore are clean and free of burrs before seating the spring. Do not compress the spring beyond the rated maximum operating deflection to avoid premature fatigue failure.
