Associated Spring Raymond 203-720 Die Spring 5 in Light-duty

Product Description

The ASSOCIATED SPRING RAYMOND 203-720 is a light-duty die spring engineered for use in stamping dies, press tooling, and similar industrial applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force characteristics and reliable cycle life under repeated compression loads. It carries a free length of 5 inches (127 mm), a maximum deflection of 2.008 inches (51 mm), and a maximum deflection load of 424.21 pounds (1887 N). The green color coding follows ISO 10243 standards, identifying this unit as a light-duty spring. Maintenance technicians and tool-and-die professionals install this type of spring during die assembly or routine tooling maintenance.

This spring is suited for installation in stamping and forming dies where controlled return force is required. The 40 mm hole diameter and 20 mm rod diameter sizing makes it compatible with standard die sets and guided spring pockets in that dimensional range. It is commonly specified in light-duty press tooling applications where lower load rates are appropriate for the material being formed or the cycle frequency of the press. This spring conforms to ISO 10243 and is classified under UNSPSC code 31161905.

Key Features

• Light-duty rating per ISO 10243, color-coded green for easy identification in multi-spring die setups
• Trapezoidal wire cross-section provides higher load capacity per unit length compared to round wire designs
• Chromium alloy steel construction for durability under cyclic compression loads
• 5 inch (127 mm) free length with 2.008 inch (51 mm) maximum deflection travel
• Maximum deflection load of 424.21 pounds (1887 N)
• 40 mm hole diameter and 20 mm rod diameter for compatibility with standard die spring pockets

Compatibility

Designed for use in stamping and forming dies with a 40 mm hole diameter pocket and a 20 mm guide rod, conforming to ISO 10243 light-duty die spring specifications.

Installation Notes

Die springs are installed by tool-and-die technicians and press maintenance personnel. Always de-energize and lock out the press before servicing any die components. Ensure the guide rod and spring pocket dimensions match the specified rod and hole diameters before installation to prevent buckling or misalignment. Do not compress the spring beyond its rated maximum deflection of 51 mm to avoid permanent set or premature failure.
