Dayton Lamina 9-2410-36 Die Spring Extra Heavy-duty Yellow

Product Description

The DAYTON LAMINA 9-2410-36 is an extra heavy-duty die spring engineered for high-load tooling and stamping applications. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a free length of 2-1/2 inches. Constructed from chromium-vanadium steel and color-coded yellow to indicate extra heavy-duty load rating, this spring delivers a maximum deflection load of 1,518 pounds at a maximum deflection of 0.63 inches. The D-shaped wire profile and tight dimensional tolerances make it suitable for precision die sets used in metal forming and press tooling environments.

This die spring is intended for use in industrial die sets, stamping presses, and precision tooling fixtures where consistent spring force and reliable cycle life are required. It is well suited for automotive tooling, metal fabrication shops, and any production environment demanding high-load spring performance within a compact envelope. The yellow color coding allows for fast visual identification of load class during tooling assembly and maintenance.

Key Features

• Extra heavy-duty load rating with a maximum deflection load of 1,518 pounds
• 1-1/2 inch hole diameter and 3/4 inch rod diameter for precise die set fitment
• 2-1/2 inch free length with a maximum deflection of 0.63 inches (25 percent maximum operating deflection)
• Chromium-vanadium steel construction for high fatigue resistance and durability
• D-shaped wire profile for consistent seating and load distribution
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards for interchangeability and quality

Compatibility

Designed as an ISO 10243-compliant replacement or direct-fit die spring for extra heavy-duty tooling applications requiring a 1-1/2 inch hole diameter and 3/4 inch rod diameter with a 2-1/2 inch free length.

Installation Notes

Die spring installation should be performed by qualified toolmakers or die maintenance technicians with the press fully de-energized, locked out, and blocked against movement. Ensure the mating rod and pocket dimensions conform to the spring specifications to prevent buckling or side loading. Do not compress the spring beyond the rated maximum operating deflection, as exceeding this limit will reduce service life and may cause spring failure.
