Associated Spring Raymond 205-307 Die Spring Red Strong

Product Description

The ASSOCIATED SPRING RAYMOND 205-307 is a heavy-duty die spring designed for use in stamping dies, punch press tooling, and similar industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a Strong duty rating and a maximum deflection load of 127.02 pounds (565 N). The free length is 1.75 inches (44.00 mm), with a maximum deflection of 13.20 mm. The red color coding identifies the Strong duty rating at a glance on the shop floor, helping toolmakers and die maintenance technicians quickly select the correct spring during setup or replacement.

This die spring is suited for applications in metal stamping, forming, and die-making operations where consistent spring force and reliable cycling are required. It fits into tooling bores with a 16.00 mm hole diameter and is designed for use over an 8.00 mm guide rod. Typical end users include tool and die makers, press room technicians, and industrial maintenance personnel working with standard die spring tooling assemblies. The spring conforms to ISO 10243 standards, making it compatible with tooling engineered to that specification.

Key Features

• Strong duty rating identified by red color coding per ISO 10243
• Trapezoidal wire cross-section for higher load capacity in a compact profile
• Chromium alloy steel construction for fatigue resistance under repeated cycling
• Maximum deflection load of 127.02 pounds (565 N)
• Free length of 1.75 inches (44.00 mm) with 13.20 mm travel to solid load
• Conforms to ISO 10243 for standardized die spring interchangeability

Compatibility

Designed as an ISO 10243-compliant die spring for use in standard stamping die assemblies requiring a 16.00 mm hole diameter, 8.00 mm guide rod, and Strong duty rating.

Installation Notes

Die springs should be installed by qualified tool and die makers or press room technicians familiar with tooling assembly procedures. Always confirm the bore diameter and guide rod dimensions match the spring specifications before installation. De-energize and lock out all press equipment before servicing or replacing die springs. Never exceed the rated maximum deflection, as compressing a die spring to solid repeatedly will reduce service life.
