Associated Spring Raymond 103-740 Die Spring 10 in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-740 is a medium-duty die spring designed for use in stamping dies, punch presses, and tooling fixtures. It features a trapezoidal wire profile that delivers a higher load capacity per unit of compressed length compared to round-wire springs. The 103-740 has a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 10 inch free length. It carries a maximum deflection load of 500 pounds and allows up to 5 inches of maximum deflection at a spring rate of 106 pounds per inch. Constructed from chromium alloy steel, it is suited for demanding press tooling environments where consistent force and long cycle life are required.

This spring is a direct fit for standard die sets used in metal stamping, forming, and blanking operations in industrial manufacturing facilities. The blue color coding follows the ISO 10243 standard convention for medium-duty die springs, making it easy to identify load class during tooling setup and maintenance. It is typically installed and serviced by tool and die makers, maintenance machinists, and industrial technicians working on hydraulic or mechanical press tooling. The 1-1/2 inch hole diameter and 3/4 inch rod diameter suit common die post and rod configurations found in both prototype and production tooling.

Key Features

• Trapezoidal wire cross-section provides higher load density than round-wire die springs of the same envelope size
• 500 pound maximum deflection load with a spring rate of 106 pounds per inch
• 5 inch maximum deflection over a 10 inch free length
• Blue color coding identifies medium-duty load class per ISO 10243 convention
• Chromium alloy steel construction for high-cycle fatigue resistance in press tooling
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for standard medium-duty stamping die sets using a 1-1/2 inch hole diameter and 3/4 inch rod diameter configuration.

Installation Notes

Installation is typically performed by tool and die makers or maintenance machinists during die build or scheduled tooling maintenance. Always relieve all press pressure and lock out the press ram before removing or replacing die springs. Inspect the mating die post and rod dimensions to confirm they match the 1-1/2 inch hole and 3/4 inch rod specifications before installation. Do not exceed the rated maximum deflection of 5 inches, as over-compression will reduce service life and may cause spring failure.
