Associated Spring Raymond 204-148 Die Spring 12in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-148 is a heavy-duty die spring engineered for use in stamping dies, presses, and tooling fixtures where consistent, repeatable force is required. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers higher load capacity and longer service life compared to standard round-wire springs. It carries a free length of 12 inches (305 mm), a rod diameter of 5 mm, and a hole diameter of 10 mm. The blue color designation indicates its load category within the ISO 10243 die spring classification system. This part is installed by tooling engineers, die makers, and press maintenance technicians.

The 204-148 is suited for industrial press tooling, injection mold assemblies, and metal stamping applications where precise spring travel and repeatable load characteristics are critical. With a maximum deflection of 116 mm and a maximum deflection load of 185.60 N, it is appropriate for light-to-medium load tooling setups. Its ISO 10243 compliance makes it a direct-fit replacement in applications specifying international standard die spring geometry. Both OEM tooling builds and aftermarket die maintenance are common use cases.

Key Features

• Trapezoidal wire cross-section provides higher load density than round-wire equivalents
• Chromium alloy steel construction for durability under cyclic compression loads
• Blue color code designates light load class per ISO 10243 standard
• 12 inches (305 mm) free length with 116 mm maximum deflection travel
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems
• TUV Rheinland registered and ANAB accredited production facility

Compatibility

Designed as an ISO 10243-compliant die spring for use in stamping dies, press tooling, and mold assemblies requiring a 10 mm hole diameter, 5 mm rod diameter, and 305 mm free length with a blue light-load classification.

Installation Notes

Die spring replacement is performed by qualified tooling technicians or die maintenance personnel. The press or tooling fixture must be fully de-energized, de-pressurized, and locked out before spring removal or installation. Verify that the rod diameter and hole diameter clearances match the tooling bore and guide rod dimensions before seating the spring. Do not compress the spring beyond its rated maximum deflection of 116 mm, as exceeding travel-to-solid load limits accelerates fatigue failure.
