Associated Spring Raymond 203-518 Light-duty Die Spring

Product Description

The ASSOCIATED SPRING RAYMOND 203-518 is a light-duty die spring designed for use in stamping dies, punch press tooling, and related industrial fixture applications. It features a trapezoidal wire shape and is manufactured from chromium alloy steel, offering consistent load performance across compression cycles. The spring carries a free length of 4.5 inches (115 mm), a rod diameter of 12.5 mm, and a hole diameter of 25 mm. At maximum deflection of 46 mm, it delivers a load of 193.38 pounds-force (860.20 N). The green color coding follows ISO 10243 standards, identifying this unit as a light-duty rated spring. Licensed toolmakers, die setters, and industrial maintenance technicians are the typical installers.

This spring is suited for light-duty compression applications in metal stamping dies, injection mold tooling, and precision fixture assemblies. It is used in both production and maintenance environments where controlled spring return force is required. The ISO 10243 compliance makes it interchangeable within systems specifying color-coded die springs of the same dimensional class. It is appropriate for horizontal or vertical mounting configurations as the tooling design allows.

Key Features

• Light-duty rating with green color coding per ISO 10243
• Trapezoidal wire cross-section for higher load capacity relative to round wire of the same envelope
• Chromium alloy steel construction for durability under repeated compression cycles
• 4.5-inch (115 mm) free length with 46 mm maximum deflection travel
• Maximum deflection load of 193.38 lb (860.20 N)
• Rod diameter of 12.5 mm and hole diameter of 25 mm for standard die post fitment

Compatibility

Designed as an ISO 10243-compliant light-duty die spring compatible with tooling applications requiring a 25 mm hole diameter, 12.5 mm rod diameter, and 115 mm free length within the green duty-class designation.

Installation Notes

Die springs are installed by toolmakers or die maintenance technicians. Always de-energize and lock out all press and hydraulic equipment before servicing tooling. Verify that the rod and hole diameters in the die set match the spring dimensions before installation. Do not exceed the rated maximum deflection to avoid permanent set or premature fatigue failure.
