Dayton Lamina 9-2010-36 Die Spring Extra Heavy-duty Yellow

Product Description

The DAYTON LAMINA 9-2010-36 is an extra heavy-duty die spring engineered for use in metal stamping dies, punch presses, and precision tooling applications. Built from chromium-vanadium steel, it delivers a maximum deflection load of 957 pounds at a maximum deflection of 0.63 inches. The spring features a D-shaped wire cross-section and a yellow color code that identifies the extra heavy-duty rating at a glance. With a 1-1/4 inch hole diameter, 5/8 inch rod diameter, and a free length of 2-1/2 inches, this spring fits standard die sets and tooling fixtures. Tool and die makers, press technicians, and precision machining professionals are the primary installers.

This spring is intended for use in metal stamping, forming, and progressive die tooling where consistent, high-force spring return is required. The extra heavy-duty classification makes it appropriate for high-cycle production tooling that demands reliable load performance over extended service. The ISO 10243 compliance ensures dimensional interchangeability with other standards-based die springs across tooling systems. With a maximum operating deflection of 25 percent and a travel to solid load of 0.75 inches, it is suited for applications where controlled deflection and repeatable force are critical to part quality and die longevity.

Key Features

• Extra heavy-duty rating with a maximum deflection load of 957 pounds
• Chromium-vanadium steel construction for high-cycle fatigue resistance
• D-shaped wire cross-section for consistent seating and load distribution
• Yellow color coding for fast identification of duty rating in the field
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards
• Maximum operating deflection of 25 percent with 0.63 inches maximum deflection

Compatibility

Designed as an ISO 10243-compliant replacement die spring for standard tooling fixtures requiring a 1-1/4 inch hole diameter, 5/8 inch rod diameter, and 2-1/2 inch free length in extra heavy-duty applications.

Installation Notes

Die spring replacement is performed by qualified tool and die technicians or press maintenance personnel. Always de-energize and lockout the press before disassembling any die set. Ensure the rod and bore dimensions of the die set match the spring specifications before installation to prevent binding or misalignment. Do not compress the spring beyond the rated maximum deflection to avoid premature fatigue failure.
