Associated Spring Raymond 203-848 Die Spring 12 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-848 is a light-duty die spring designed for use in metal stamping dies, punch press tooling, and similar industrial tooling applications. Built from chromium alloy steel, it features a trapezoidal wire cross-section that increases contact area and improves load distribution compared to round-wire springs. The spring has a free length of 12 inches (305 mm), a hole diameter of 50 mm, and a rod diameter of 25 mm. It is color-coded green to indicate its light-duty rating, making identification fast during tooling setup or maintenance. Rated to a maximum deflection load of 781.66 pounds (3477 N) with a maximum deflection of 122 mm, this spring meets ISO 10243 standards.

This die spring is suited for light-duty stamping and forming die sets in both production and toolroom environments. It is installed by tool and die makers, press room technicians, and industrial maintenance professionals. The green color-code designation follows the ISO 10243 die spring classification system, allowing straightforward cross-referencing and replacement sourcing. Typical applications include stripper plate return, component ejection, and pad pressure functions within progressive, compound, or single-stage tooling setups.

Key Features

• Chromium alloy steel construction for fatigue resistance under cyclic loading
• Trapezoidal wire shape increases load-bearing surface area over round-wire designs
• Green color-coding identifies light-duty rating per ISO 10243 classification
• 12-inch (305 mm) free length accommodates tooling with extended travel requirements
• Maximum deflection load of 781.66 pounds (3477 N) at 122 mm travel to solid
• UNSPSC Code 31161905 for procurement and catalog classification

Compatibility

Designed as an ISO 10243-compliant light-duty die spring for use in standard die sets requiring a 50 mm hole diameter and 25 mm rod diameter with a 12-inch free length.

Installation Notes

Die springs are installed by qualified tool and die makers or press room technicians. Always de-energize and lockout the press before removing or installing die components. The spring must be seated concentrically on the guide rod and within the counterbore to prevent lateral loading and premature fatigue failure. Do not compress beyond the rated maximum deflection of 122 mm or operate the spring at solid height, as this will reduce service life significantly.
