Associated Spring Raymond 203-940 Die Spring 10 in Light-duty

Product Description

The ASSOCIATED SPRING RAYMOND 203-940 is a light-duty die spring engineered for use in tooling, stamping, and press applications. Built from chromium alloy steel with a trapezoidal wire shape, it provides consistent return force and extended service life under repetitive compression cycles. The spring measures 10 inches in free length with a maximum deflection of approximately 4.02 inches, and it delivers a maximum deflection load of 1,077.73 pounds. The green color coding identifies it as a light-duty rating per ISO 10243 standards. This part is typically installed by toolmakers, die setters, and maintenance technicians working with punch and die assemblies.

This die spring is suited for industrial press tooling, injection mold assemblies, and stamping die applications where controlled, repeatable spring force is required. The trapezoidal wire cross-section increases the active material volume compared to round wire, allowing higher load capacity within the same envelope. It fits inside a hole diameter of 63.00 mm and mounts over a rod diameter of 38.00 mm, making it compatible with standard die set configurations that follow ISO 10243 specifications.

Key Features

• Light-duty rating with green color coding per ISO 10243 standard
• Trapezoidal wire shape for higher load density versus round-wire springs
• Chromium alloy steel construction for durability under cyclic compression
• 10 inches free length with 4.02 inches maximum deflection travel
• Maximum deflection load of 1,077.73 pounds (4,794 N)
• Designed to fit 63.00 mm hole diameter and 38.00 mm rod diameter

Compatibility

Designed as an ISO 10243-compliant replacement or direct-install die spring for light-duty stamping and press tooling applications requiring a 63.00 mm hole diameter, 38.00 mm rod diameter, and 254.00 mm free length.

Installation Notes

Die spring installation is typically performed by toolmakers or die maintenance technicians. Always de-energize and lockout the press before accessing the die set. Ensure the mating hole and rod dimensions match the spring specifications before installation to prevent buckling or binding. Do not compress the spring beyond its rated maximum deflection travel during operation.
