Dayton Lamina 9-2448-26 Heavy-duty Die Spring 12 Inches Red

Product Description

The DAYTON LAMINA 9-2448-26 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and precision tooling applications. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 12 inch free length, making it suitable for high-load tooling setups that demand consistent force and reliable deflection performance. Constructed from chromium-vanadium steel with a D-shaped wire profile, this spring delivers a maximum deflection load of 1,034 pounds and a maximum deflection of 3.6 inches. The red color coding indicates a heavy-duty load rating per ISO 10243 standards. Tool and die makers, press room technicians, and industrial maintenance professionals install this spring in production tooling environments.

This die spring is designed for use in metal stamping dies, forming tools, bending fixtures, and similar industrial press tooling where repeatable spring force and stroke accuracy are critical. The 12 inch free length accommodates applications requiring extended travel, and the heavy-duty rating suits high-cycle production tooling. The spring meets ISO 10243 international standards, ISO 9001:2015 quality registration requirements, and NAAMS (North American Automotive Metric Standard) specifications, making it appropriate for automotive tooling programs and other precision manufacturing environments.

Key Features

• Heavy-duty load rating with a maximum deflection load of 1,034 pounds
• 12 inch free length with a maximum deflection of 3.6 inches (30 percent maximum operating deflection)
• 1-1/2 inch hole diameter and 3/4 inch rod diameter for standard die set fitment
• Chromium-vanadium steel construction with D-shaped wire cross-section for high fatigue resistance
• Red color coding per ISO 10243 heavy-duty classification
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an ISO 10243-compliant heavy-duty die spring for use in standard punch and die tooling applications requiring a 1-1/2 inch hole diameter, 3/4 inch rod diameter, and 12 inch free length configuration.

Installation Notes

Die springs of this type are installed and serviced by tool and die makers or press room maintenance technicians. Always de-energize and lockout the press before removing or installing die springs. Inspect the mating hole diameter and guide rod diameter for proper fit before installation; an undersized or worn guide rod can cause lateral loading and premature spring failure. Never compress a die spring beyond its rated maximum operating deflection, as exceeding the travel-to-solid dimension can cause permanent set or fracture.
