Associated Spring Raymond 206-740 Die Spring 40mm Extra Strong

Product Description

The ASSOCIATED SPRING RAYMOND 206-740 is a heavy-duty die spring engineered for tooling, stamping, and press applications that demand consistent, repeatable force. Built to an Extra Strong duty rating, this spring features a trapezoidal wire cross-section and is manufactured from chromium alloy steel for high fatigue resistance under cyclic loading. It has a 40 mm hole diameter, a 20 mm rod diameter, and a 12-inch free length. Maximum deflection load reaches 6,848 newtons (N) at a maximum deflection of 64 mm. The yellow color coding identifies the Extra Strong load class per ISO 10243. Toolmakers, die setters, and precision manufacturing technicians are the primary installers of this component.

This die spring is suited for use in metal stamping dies, injection molds, progressive tooling, and industrial press assemblies where high spring force in a compact envelope is required. The 40 mm outer diameter and 20 mm rod diameter make it compatible with standard die set configurations calling for Extra Strong class springs at this dimensional envelope. Confirm free length and deflection requirements against your tooling drawings before installation.

Key Features

• Extra Strong duty rating for high-load cyclic press and stamping applications
• Trapezoidal wire cross-section maximizes load capacity within the coil envelope
• Chromium alloy steel construction provides high fatigue life under repeated deflection
• 6,848 N maximum deflection load with 64 mm maximum deflection travel
• Yellow color coding per ISO 10243 for quick load-class identification
• 12-inch free length in a 40 mm hole diameter / 20 mm rod diameter form factor

Compatibility

Designed as an ISO 10243-compliant Extra Strong die spring for standard tooling and stamping die assemblies requiring a 40 mm outer diameter, 20 mm rod diameter, and 12-inch free length.

Installation Notes

Die springs should be installed by qualified toolmakers or die maintenance technicians familiar with press tooling safety procedures. Always de-energize and lock out the press before accessing the die set. Inspect the spring pocket and guide rod for proper diameter clearance before seating the spring. Never compress a die spring beyond its rated maximum deflection, as over-compression can cause premature fatigue failure or spring fracture.
