Associated Spring Raymond 203-948 Die Spring 12 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-948 is a heavy-duty die spring engineered for use in industrial stamping, forming, and press tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force and extended fatigue life under high-cycle conditions. It features a 12-inch free length, a hole diameter of 63 millimeters, and a rod diameter of 38 millimeters. With a maximum deflection load of 4,660.40 newtons and a spring rate of 218.13 newtons per millimeter, this unit is suited for demanding die sets where precise, repeatable spring performance is required. Color-coded green for quick identification in the field.

This die spring is designed for use in metal stamping dies, injection molds, press tooling, and similar industrial equipment where controlled compression and return force are critical. The green color designation indicates its load category within standard die spring classification systems. It is installed by tool and die makers, maintenance technicians, and machine builders working on hydraulic or mechanical press systems. The 305-millimeter free length and 122-millimeter maximum deflection make it appropriate for medium-to-heavy duty tooling configurations requiring substantial travel.

Key Features

• Chromium alloy steel construction for high fatigue resistance and long service life
• Trapezoidal wire shape maximizes contact area and spring rate efficiency
• 12-inch (305 mm) free length with 122 mm maximum deflection travel
• Spring rate of 218.13 N/mm for predictable, consistent load performance
• Green color-coding allows fast visual identification of load category
• Meets ISO 10243 standards for die springs

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for industrial stamping and press tooling applications requiring an ISO 10243 green-category spring with a 63 mm hole diameter and 38 mm rod diameter.

Installation Notes

Die springs are installed by qualified tool and die technicians or industrial maintenance personnel. Always de-energize and lock out the press before disassembling the die set. Ensure the mating hole and rod dimensions match the spring specifications before installation to prevent side loading or premature failure. Do not compress the spring beyond its rated maximum deflection of 122 millimeters.
