Associated Spring Raymond 206-508 Die Spring 2 in Extra Strong

Product Description

The ASSOCIATED SPRING RAYMOND 206-508 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and mold tooling applications. Built from chromium alloy steel and rated Extra Strong duty, this spring delivers a maximum deflection load of 606.42 pounds (2697.50 N) across a maximum deflection of 13.00 millimeters. The trapezoidal wire cross-section is the defining characteristic of ISO-standard die springs, providing greater load capacity and consistent performance compared to round-wire alternatives. The yellow color coding identifies the Extra Strong duty rating per ISO 10243 standards, making identification and replacement straightforward in a production tooling environment. Licensed machinists, tool and die makers, and maintenance technicians are the primary installers.

This die spring is suited for metal stamping, injection mold tooling, and progressive die applications where consistent spring force and long cycle life are required. It fits into standard die sets where the mounting hole accommodates a 25.00 mm diameter and the guide rod measures 12.50 mm in diameter. With a free length of 51.00 mm (approximately 2 inches) and a travel-to-solid of 13.00 mm, it is appropriate for compact die assemblies requiring high force output in a limited stroke envelope. Typical installations include stripper plates, pressure pads, and return mechanisms in industrial tooling.

Key Features

• Extra Strong duty rating identified by yellow color coding per ISO 10243
• Trapezoidal wire profile provides higher load density than round-wire die springs
• Maximum deflection load of 606.42 pounds (2697.50 N) at 13.00 mm travel
• Chromium alloy steel construction for high fatigue resistance in cyclic applications
• 25.00 mm hole diameter and 12.50 mm rod diameter for standard tooling fitment
• Compliant with ISO 10243 die spring standard

Compatibility

Designed as an ISO 10243 compliant die spring for standard tooling applications requiring a 25.00 mm hole diameter, a 12.50 mm guide rod diameter, and a 51.00 mm free length in Extra Strong duty rating.

Installation Notes

Die spring replacement is performed by tool and die makers or qualified maintenance technicians with the machine fully de-energized and all stored hydraulic or mechanical energy relieved before disassembly. Ensure the guide rod and hole are free of burrs or contamination before seating the spring, as surface damage accelerates fatigue failure. Never compress a die spring beyond its rated maximum deflection; exceeding travel-to-solid length will cause permanent set or fracture. Follow shop safety protocols and applicable OSHA machine guarding requirements when working on active tooling.
