Associated Spring Raymond 205-724 Die Spring Red Strong Duty

Product Description

The ASSOCIATED SPRING RAYMOND 205-724 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and tooling fixtures. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent, high-cycle performance under demanding load conditions. It carries a strong duty rating and meets ISO 10243 standards. The 40 mm hole diameter, 20 mm rod diameter, and 152 mm free length define its fitment envelope, while a maximum deflection load of 4,830 N (1,085.83 lb.) reflects its capacity for heavy tooling applications. Die and tool makers, as well as press maintenance technicians, are the typical installers.

This spring is suited for industrial tooling environments where strong-duty compression springs are required inside die sets, molds, or mechanical presses. The red color coding follows ISO 10243 color classification for strong-duty springs, making identification straightforward during die setup and maintenance. Applications include blanking, forming, drawing, and progressive die operations across light and heavy manufacturing environments.

Key Features

• Strong duty rating per ISO 10243 color-coded red classification
• Trapezoidal wire profile for higher load capacity relative to round-wire springs of the same envelope
• Chromium alloy steel construction for high fatigue resistance under repeated cycling
• Maximum deflection of 46 mm with a corresponding load of 4,830 N (1,085.83 lb.)
• 40 mm hole diameter and 20 mm rod diameter for direct drop-in fit in standard die sets

Compatibility

Designed as an ISO 10243 compliant strong-duty die spring for use in standard die sets and tooling fixtures requiring a 40 mm hole diameter and 20 mm rod diameter with a 152 mm free length.

Installation Notes

Die springs are installed and serviced by toolroom machinists and press maintenance technicians. Before replacing a die spring, lock out and tag out the press per your facility energy control program. Confirm that the replacement spring hole diameter, rod diameter, free length, and duty rating match the original tooling specification. Do not exceed the published maximum deflection value, as over-compression will reduce service life and may cause premature fatigue failure.
