Associated Spring Raymond 203-628 Die Spring 7 in Light-duty

Product Description

The ASSOCIATED SPRING RAYMOND 203-628 is a light-duty die spring designed for use in metal stamping dies, punch presses, and tooling fixtures. Built from chromium alloy steel with a trapezoidal wire shape, it delivers consistent force characteristics across its compression cycle. The spring has a free length of 7 inches (178 mm) and a maximum deflection of 2.795 inches (71 mm), with a maximum deflection load of 290.50 pounds (1292.20 N). The green color coding follows ISO 10243 standards, identifying this as a light-duty unit. It is installed by tool-and-die makers, machinists, and maintenance technicians working in press and die applications.

This die spring is suited for light-duty compression applications in industrial tooling and stamping operations. It fits into die sets with a hole diameter of 1.26 inches (32 mm) and mounts over a rod diameter of 0.63 inches (16 mm). Typical installations include stripper plates, pressure pads, and component ejection systems within progressive, compound, or transfer dies. The ISO 10243 conformance makes it interchangeable with other compliant light-duty green die springs of matching dimensions.

Key Features

• Light-duty rating per ISO 10243, color-coded green for quick field identification
• Trapezoidal wire cross-section provides higher load capacity relative to round wire at equivalent size
• Chromium alloy steel construction for durability under repeated compression cycles
• Free length of 7 inches (178 mm) with maximum deflection of 2.795 inches (71 mm)
• Maximum deflection load of 290.50 pounds (1292.20 N)
• Fits 1.26-inch (32 mm) hole diameter and 0.63-inch (16 mm) rod diameter

Compatibility

Conforms to ISO 10243 for light-duty die springs. Designed as a direct replacement for any ISO 10243-compliant light-duty green die spring with a 32 mm hole diameter, 16 mm rod diameter, and 178 mm free length.

Installation Notes

Die springs are installed by qualified tool-and-die makers or maintenance technicians. Always ensure the press or tooling is fully de-energized and locked out before removing or replacing die springs. The spring should be seated concentrically on the guide rod and within the counterbore to prevent side loading. Do not compress the spring beyond its rated maximum deflection, as over-compression accelerates fatigue and may cause premature failure.
