Associated Spring Raymond 206-840 Die Spring 50mm Yellow Extra Strong

Product Description

The ASSOCIATED SPRING RAYMOND 206-840 is a heavy-duty die spring engineered for use in stamping dies, punch press tooling, and other industrial spring applications requiring consistent, high-load performance. It features a 50.00 mm hole diameter, a 25.00 mm rod diameter, and a 12-inch free length, making it suited for demanding deflection cycles. Constructed from chromium alloy steel with a trapezoidal wire cross-section, this Extra Strong rated spring delivers a maximum deflection load of 9792.00 N with a maximum deflection of 64.00 mm. Qualified toolmakers, die setters, and maintenance technicians are the typical installers.

This die spring is used in metal stamping, forming, and press tooling applications where high spring forces are required in a compact envelope. The Extra Strong duty rating and yellow color coding follow ISO 10243 standards, making it straightforward to identify and specify within a multi-spring die set. It is appropriate for both new tooling builds and replacement of worn or fatigued springs in existing die assemblies operating under heavy-cycle or high-load conditions.

Key Features

• Extra Strong duty rating with a maximum deflection load of 9792.00 N
• Trapezoidal wire cross-section for higher load capacity compared to round wire springs
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• ISO 10243 compliant - yellow color coding identifies Extra Strong duty class
• 50.00 mm hole diameter and 25.00 mm rod diameter for precise die fit
• 64.00 mm maximum deflection (travel to solid load)

Compatibility

Designed as an ISO 10243 standard die spring for use in stamping dies, press tooling, and similar industrial fixture applications requiring a 50.00 mm bore and 25.00 mm rod fit with an Extra Strong load rating.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance technicians following the press or die manufacturer's design specifications. Always relieve all press tonnage and lock out the press ram before removing or installing die springs. Do not compress the spring beyond the rated maximum deflection of 64.00 mm, as exceeding travel-to-solid load will shorten fatigue life and risk spring failure. Inspect mating hole and rod surfaces for burrs or damage before installation to prevent uneven loading.
