Associated Spring Raymond 103-507 Die Spring Blue Medium-duty

Product Description

The ASSOCIATED SPRING RAYMOND 103-507 is a medium-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire shape, this spring delivers a spring rate of 320 pounds per inch and a maximum deflection load of 262.5 pounds. The blue color coding identifies it as a medium-duty rating per standard die spring classifications. It is designed for installation by tool and die makers, maintenance technicians, and machine shop personnel working with press tooling and fixture assemblies.

This die spring is suited for medium-load tooling applications in stamping, forming, and press operations. The 1 inch hole diameter accommodates a standard guide post, while the 1/2 inch rod diameter allows guided mounting on a center rod. With a free length of 1.75 inches and a maximum deflection of 0.88 inches, it fits into compact die sets where controlled, repeatable spring force is required. Manufactured to ISO 9001:2008 and ISO/TS 16949:2009 standards, it meets quality requirements common in precision tooling environments.

Key Features

• Trapezoidal wire shape provides higher load capacity in a compact free length compared to round wire springs
• Spring rate of 320 pounds per inch delivers consistent, predictable deflection force
• Maximum deflection load of 262.5 pounds at 0.88 inches of travel
• Chromium alloy steel construction resists fatigue under high-cycle press operation
• Blue color coding indicates medium-duty rating for straightforward identification during maintenance
• Manufactured under ANAB-accredited ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for medium-duty stamping dies and press tooling that require a 1 inch outer diameter, 1/2 inch rod diameter, and 1.75 inch free length spring with blue medium-duty rating.

Installation Notes

Die springs are installed by qualified tool and die technicians or maintenance machinists. Always de-energize and lock out the press before replacing springs in a die set. Ensure the guide post and rod dimensions match the spring bore and rod diameter specifications before installation. Never compress a die spring beyond its rated maximum deflection, as over-compression accelerates fatigue and can cause premature failure.
