Associated Spring Raymond 203-516 Die Spring 4 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-516 is a heavy-duty die spring engineered for use in stamping dies, press tooling, and industrial mold assemblies. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 120.48 N/mm and a maximum deflection load of 865.10 N over a maximum deflection of 41.00 mm. The green color coding identifies its load class for fast identification in production and maintenance environments. With a free length of 4 inches (102.00 mm), this spring is a standard-format component installed by tool-and-die technicians, press maintenance crews, and industrial maintenance professionals.

This die spring is suited for use in progressive dies, compound dies, and injection mold assemblies operating in light to medium load applications. The green load class is commonly used where controlled return force and consistent stroke repeatability are required. It fits a 25.00 mm hole diameter and accepts a 12.50 mm rod diameter, making it compatible with standard ISO 10243 die spring tooling configurations.

Key Features

• Trapezoidal wire cross-section provides higher load capacity and longer fatigue life compared to round wire die springs
• Chromium alloy steel construction resists wear and deformation under repeated compression cycles
• Green color coding identifies the light load class for quick visual sorting on the shop floor
• Conforms to ISO 10243 standards for interchangeability with other ISO-dimensioned die springs
• 4 inches (102.00 mm) free length with 41.00 mm travel to solid load
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality management systems

Compatibility

Dimensioned to ISO 10243 standards with a 25.00 mm hole diameter and 12.50 mm rod diameter, making it a direct-fit replacement in any tooling assembly designed to that standard.

Installation Notes

Die springs are installed by qualified tool-and-die technicians and press maintenance personnel. Always de-energize and lock out the press before removing or replacing die springs. Inspect the spring pocket and guide rod for wear or damage before installing a new spring. Do not compress the spring beyond its stated maximum deflection to avoid premature failure.
