Dayton Lamina 9-0806-21 Die Spring 1.5 in Blue Medium Duty

Product Description

The DAYTON LAMINA 9-0806-21 is a medium-duty die spring designed for use in stamping dies, molds, and precision tooling applications. Built from chromium-vanadium steel, this spring delivers consistent, reliable force across repeated compression cycles. It features a 0.5-inch hole diameter, a 9/32-inch rod diameter, and a 1.5-inch free length. The D-shaped wire profile resists rotation during compression and maintains accurate load characteristics over extended service life. A maximum deflection load of 61 pounds and a maximum deflection of 0.56 inches make this spring well-suited for medium-force clamping and stripping operations in production tooling environments. Licensed machinists, tool and die makers, and industrial maintenance technicians are the primary installers.

This die spring is intended for use in stamping dies, injection molds, jigs, fixtures, and similar precision metalworking tooling. The blue color coding identifies medium-duty load class per ISO 10243 international standards, allowing quick visual identification during tooling assembly and maintenance. It fits over a 9/32-inch guide rod and seats inside a 0.5-inch pocket, making it compatible with standard medium-duty die spring pocket layouts used across production tooling in automotive, aerospace, and general manufacturing environments.

Key Features

• Chromium-vanadium steel construction for high fatigue resistance and long cycle life
• D-shaped wire profile resists rotation and maintains consistent load alignment
• Blue color coding indicates medium-duty load class per ISO 10243
• Maximum deflection load of 61 pounds at 0.56 inches maximum deflection
• 37.5 percent maximum operating deflection rating
• Meets ISO 10243, ISO 9001:2015, and NAAMS standards

Compatibility

Designed as an OEM-style medium-duty die spring replacement for stamping dies, molds, and precision tooling assemblies requiring a 0.5-inch hole diameter and 9/32-inch rod diameter with a 1.5-inch free length.

Installation Notes

Die springs should be installed by qualified tool and die makers or machinist personnel familiar with press tooling safety procedures. Always de-energize and lockout the press or machine before disassembling tooling. Ensure the guide rod diameter and pocket bore match the spring specifications before installation to prevent binding or misalignment. Do not exceed the maximum operating deflection of 37.5 percent during normal production cycles, as exceeding this value accelerates fatigue and reduces service life.
