Associated Spring Raymond 103-816 Die Spring Blue Medium-duty

Product Description

The ASSOCIATED SPRING RAYMOND 103-816 is a medium-duty die spring designed for use in stamping dies, punch presses, and similar tooling applications. It features a 2-inch hole diameter, a 1-inch rod diameter, and a 4-inch free length. The spring is wound from chromium alloy steel wire with a trapezoidal wire cross-section, which provides consistent load performance and extended cycle life compared to round-wire designs. At maximum deflection of 2 inches, it delivers a load capacity of 1,200 pounds, with a spring rate of 600 pounds per inch. The blue color coding identifies its medium-duty rating per standard die spring classification. Licensed tool and die technicians, press operators, and maintenance machinists are the typical installers.

This die spring is suited for medium-duty tooling setups in both production and maintenance environments. It is commonly installed in stamping dies, forming tools, injection mold assemblies, and other industrial equipment requiring controlled compression force. The 2-inch hole diameter accommodates standard die set guide posts, and the 1-inch rod diameter suits common inner pilot rod configurations. Its compact 4-inch free length fits tooling envelopes where space is limited but reliable spring return force is required across high-cycle applications.

Key Features

• Trapezoidal wire cross-section provides higher load capacity and longer fatigue life versus round-wire springs of the same envelope size
• 1,200-pound maximum deflection load at 2 inches of travel
• Spring rate of 600 pounds per inch for predictable, linear force delivery
• Chromium alloy steel construction for durability in high-cycle industrial tooling
• Blue color coding indicates medium-duty classification for quick field identification
• ISO 9001:2008 and ISO/TS 16949:2009 certified manufacturing; TUV Rheinland Registered

Compatibility

Designed as a standard medium-duty die spring for industrial tooling applications with a 2-inch hole diameter and 1-inch rod diameter. Fits standard die set configurations requiring a 4-inch free-length compression spring at this bore and rod size.

Installation Notes

Die spring installation and replacement should be performed by qualified tool and die technicians or maintenance machinists familiar with press tooling procedures. Always de-energize and lock out the press or machine before accessing the die set. Inspect the mating guide post and rod for wear, burrs, or misalignment before installing the new spring, as surface damage accelerates fatigue failure. Never compress the spring beyond its rated maximum deflection of 2 inches during setup or operation.
