Associated Spring Raymond 104-828 Die Spring 2in Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-828 is a medium heavy-duty die spring designed for use in stamping dies, punch presses, and other high-cycle tooling applications. It features a 2-inch hole diameter, a 1-inch rod diameter, and a 7-inch free length, with a trapezoidal wire profile that delivers more load capacity per unit of deflection than round wire springs. Rated for a maximum deflection load of 1,036 pounds with up to 2.59 inches of maximum deflection, this spring is built from chromium alloy steel for long service life under repeated compression cycles. It is identified by its red color coding, which corresponds to the medium heavy-duty load class.

This die spring is suited for use in metal stamping tooling, injection mold assemblies, and press tooling where consistent return force and dimensional repeatability are required. Its standardized hole and rod diameters make it a direct fit for conventional die sets using industry-standard spring pockets. Toolmakers, tool and die technicians, and maintenance machinists are the typical trades that specify and install this component.

Key Features

• 2-inch hole diameter and 1-inch rod diameter for standard die set fitment
• 7-inch free length with 2.59 inches of maximum deflection travel
• Maximum deflection load rated at 1,036 pounds
• Spring rate of 374 pounds per inch for predictable, linear force output
• Trapezoidal wire cross-section for higher load density versus round wire
• Chromium alloy steel construction for fatigue resistance in high-cycle applications
• Red color coding identifies medium heavy-duty load class per ISO die spring standards

Compatibility

Designed as an OEM-style replacement or direct substitute for standard ISO-pattern die springs with a 2-inch hole diameter, 1-inch rod diameter, and 7-inch free length in medium heavy-duty (red) load class applications.

Installation Notes

Installation is performed by toolmakers or die maintenance technicians during die build or spring replacement service. Ensure the spring pocket depth and rod clearance are verified against the free length and rod diameter before assembly. Never exceed the rated maximum deflection, as over-compression accelerates fatigue failure and can cause spring fracture. Inspect the spring for cracking or set loss at scheduled die maintenance intervals.
