Associated Spring Raymond 103-612 Die Spring Blue Medium-duty

Product Description

The ASSOCIATED SPRING RAYMOND 103-612 is a medium-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a 1-1/4 inch hole diameter, a 5/8 inch rod diameter, and a 3 inch free length. Constructed from chromium alloy steel with a trapezoidal wire shape, it delivers a spring rate of 240 pounds per inch and a maximum deflection load of 360 pounds at 1.5 inches of travel. The blue color coding identifies the medium-duty load rating at a glance, consistent with standard die spring classification conventions. Licensed tooling technicians and machine maintenance professionals are the typical installers.

This die spring is suited for use in compression applications within metal stamping dies, injection mold tooling, and general industrial machinery where consistent load performance and repeatable deflection are required. It is appropriate for both light production and repetitive-cycle tooling environments. The medium-duty rating makes it a common choice when a standard-duty spring is insufficient but a heavy-duty spring would introduce excessive load for the application.

Key Features

• Blue color coding indicates medium-duty load classification for quick field identification
• Trapezoidal wire cross-section provides higher load capacity relative to round wire springs of comparable size
• 360 pound maximum deflection load with 1.5 inches of maximum travel
• Spring rate of 240 pounds per inch for predictable, linear compression behavior
• Chromium alloy steel construction for durability under cyclic loading
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems; TUV Rheinland registered

Compatibility

Designed as a direct-fit replacement or standard component for tooling applications requiring a 1-1/4 inch hole diameter, 5/8 inch rod diameter, 3 inch free length, medium-duty die spring.

Installation Notes

Die springs are installed by qualified tooling technicians or machine maintenance personnel. Before servicing any press or die assembly, de-energize the machine, engage all mechanical safeties, and relieve stored hydraulic or pneumatic pressure. Ensure the rod and bore dimensions of the die set match the 5/8 inch rod and 1-1/4 inch hole specifications before installation. Never compress a die spring beyond its rated maximum deflection of 1.5 inches, as over-compression will reduce service life and may cause premature failure.
