Associated Spring Raymond 203-820 Die Spring 5 in Light-duty

Product Description

The ASSOCIATED SPRING RAYMOND 203-820 is a light-duty die spring designed for use in stamping dies, punch presses, and similar tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers consistent load characteristics across its deflection range. The spring measures 5 inches (127 millimeters) in free length, with a maximum deflection of 2 inches (51 millimeters) and a maximum deflection load of 814.03 pounds (3621 N). The green color coding identifies its light-duty rating per ISO 10243 standards. This spring is installed by tool and die makers, machine builders, and maintenance technicians working on mechanical press tooling.

This die spring fits applications requiring a 50 millimeter hole diameter and a 25 millimeter rod diameter. It is suited for light-duty cyclic compression in stamping dies, progressive dies, and injection mold tooling where consistent return force and fatigue resistance are required. The trapezoidal wire profile allows for higher load capacity within a compact cross-section compared to standard round wire springs of the same envelope. Packaging quantity is one piece per unit.

Key Features

• Light-duty rating with green color coding per ISO 10243
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• Trapezoidal wire cross-section for improved load density within the spring envelope
• 5 inch (127 mm) free length with 2 inch (51 mm) maximum deflection travel
• Fits 50 mm hole diameter and 25 mm rod diameter tooling configurations
• Maximum deflection load of 814.03 pounds (3621 N)

Compatibility

Designed as an ISO 10243 compliant light-duty die spring for use in stamping dies, punch press tooling, and injection mold assemblies requiring a 50 millimeter hole diameter and 25 millimeter rod diameter with a 127 millimeter free length.

Installation Notes

Die springs are installed by qualified tool and die technicians or machine maintenance personnel. Always de-energize and lock out the press or machine before servicing tooling components. Ensure the spring seat surfaces are clean, flat, and free of burrs before installation to prevent uneven loading. Do not compress the spring beyond its specified maximum deflection of 51 millimeters to avoid permanent set or premature fatigue failure.
