Dayton Lamina 9-1048-26 Die Spring Heavy-duty Red

Product Description

The DAYTON LAMINA 9-1048-26 is a heavy-duty die spring designed for use in metal stamping dies, press tooling, and industrial mold assemblies. Built from chromium-vanadium steel with a D-shaped wire cross-section, it delivers consistent, high-force return action under repeated compression cycles. The spring measures 0.625 inches in hole diameter, 0.34375 inches in rod diameter, and 12 inches in free length. It handles a maximum deflection load of 120 pounds at 3.6 inches of travel. Licensed tooling technicians and die-maintenance professionals are the primary installers. It is rated red duty and meets ISO 10243 dimensional standards.

This spring is suited for high-cycle stamping dies, injection mold tooling, and similar precision press applications where consistent spring force and dimensional repeatability are required. The heavy-duty red rating indicates higher load capacity relative to standard-duty springs of the same envelope size. It is appropriate for both production tooling environments and toolroom maintenance applications. The D-shaped wire profile improves solid-height predictability and lateral stability compared to round-wire alternatives.

Key Features

• Heavy-duty red rating for high-load tooling applications
• Chromium-vanadium steel construction for fatigue resistance under repeated cycling
• D-shaped wire cross-section for improved lateral stability and predictable solid height
• 12 inches free length with 3.6 inches maximum operating deflection
• Maximum deflection load of 120 pounds
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an ISO 10243-compliant die spring for heavy-duty stamping dies, press tools, and industrial mold assemblies requiring a 0.625-inch bore and 12-inch free length configuration.

Installation Notes

Installation is typically performed by toolroom technicians or die-maintenance personnel during press die assembly or rebuild. Always de-energize and lock out the press before servicing any spring components. Ensure the rod diameter and bore clearance match the specified 0.34375-inch rod and 0.625-inch hole dimensions before seating the spring. Do not compress the spring beyond the rated 30 percent maximum operating deflection to avoid premature fatigue failure.
