Associated Spring Raymond 206-310 Die Spring Extra Strong Yellow

Product Description

The ASSOCIATED SPRING RAYMOND 206-310 is an extra-strong die spring engineered for use in stamping dies, punch presses, and similar metal-forming tooling. It features a 16.00 mm hole diameter, an 8.00 mm rod diameter, and a free length of 2-1/2 inches (64.00 mm). The trapezoidal wire shape maximizes load capacity within a compact envelope. Wound from chromium alloy steel, this spring handles a maximum deflection load of 659.20 N at 16.00 mm of travel to solid. The yellow color coding identifies the extra-strong duty rating per ISO 10243 standards. Tool and die makers, press operators, and maintenance technicians are the primary installers.

This die spring is suited for industrial tooling applications where high force is required in a limited space. Typical install scenarios include progressive dies, blanking dies, and forming dies in manufacturing and fabrication environments. The extra-strong rating makes it appropriate when standard or heavy-duty springs are insufficient for the required press force. It can also be used in other mechanical assemblies where a guided compression spring with a known load curve is specified by the tooling designer.

Key Features

• Extra-strong duty rating with a maximum deflection load of 659.20 N
• Trapezoidal wire cross-section for higher load capacity per unit length
• Chromium alloy steel construction for durability under cyclic compressive loads
• Yellow color coding for fast visual identification per ISO 10243
• 16.00 mm hole diameter and 8.00 mm rod diameter for guided installation on standard tooling pins
• 2-1/2 inch (64.00 mm) free length with 16.00 mm maximum deflection travel

Compatibility

Designed as an OEM-style replacement or direct substitute for die spring applications requiring an ISO 10243 extra-strong class spring with a 16.00 mm hole diameter, 8.00 mm rod diameter, and 64.00 mm free length.

Installation Notes

Installation is typically performed by tool and die technicians during die setup or maintenance. Ensure the guide pin and bore dimensions match the specified rod and hole diameters before installation to prevent side loading. Always de-energize and lock out the press before accessing the die set. Do not exceed the rated maximum deflection of 16.00 mm, as compressing the spring to solid will accelerate fatigue failure.
