Associated Spring Raymond 204-740 Die Spring Medium Duty

Product Description

The ASSOCIATED SPRING RAYMOND 204-740 is a medium-duty die spring engineered for use in stamping dies, punch presses, and related tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force and fatigue resistance under repeated cycling. It has a free length of 10 inches (254 mm), a hole diameter of 40 mm, and a rod diameter of 20 mm. The blue color coding identifies it as a medium-duty load class per ISO 10243. Licensed toolmakers, die setters, and maintenance technicians are the typical installers for this component.

This die spring is designed for industrial tooling environments where controlled deflection and predictable load characteristics are required. The 204-740 provides a maximum deflection of 95 mm with a corresponding load of 642.84 pounds (2859.50 N) at solid. It is suited for use in press tooling where a medium load rating is specified and where the bore and rod dimensions match the 40 mm hole diameter and 20 mm rod diameter requirements.

Key Features

• Medium-duty load rating with blue color coding per ISO 10243
• Trapezoidal wire cross-section for higher load capacity relative to round wire
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• 10 inch (254 mm) free length with 95 mm maximum deflection travel
• 40 mm hole diameter and 20 mm rod diameter for precise die fitment
• Maximum deflection load of 642.84 pounds (2859.50 N)

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for stamping and punch die assemblies requiring a medium-duty spring with a 40 mm bore, 20 mm rod diameter, and 254 mm free length conforming to ISO 10243 specifications.

Installation Notes

Installation is typically performed by a trained toolmaker or die maintenance technician with the press de-energized and all stored energy released before disassembly. The spring must be seated squarely within the die bore with the rod centered to prevent side loading during operation. Do not compress this spring beyond its rated maximum deflection of 95 mm, as over-compression will shorten fatigue life and may cause premature failure.
