Associated Spring Raymond 205-510 Die Spring Strong Duty

Product Description

The ASSOCIATED SPRING RAYMOND 205-510 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and progressive tooling applications. Manufactured from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers high load capacity in a compact envelope. It carries a Strong duty rating, a free length of 2.5 inches (64 mm), and a maximum deflection load of 525.38 pounds (2,337 N). The red color coding follows ISO 10243 standards, immediately identifying the duty class during tooling setup and maintenance.

This die spring is suited for production tooling environments where consistent force and reliable cycle life are required. Typical applications include metal stamping dies, injection mold components, and industrial press tooling. The trapezoidal wire profile allows higher stress capacity compared to round wire springs of the same envelope, making it a common choice for Strong-duty positions in tight die spaces. Installation and replacement are performed by tool and die makers and maintenance machinists during die build or scheduled tooling maintenance.

Key Features

• Strong duty rating per ISO 10243 - color-coded red for quick visual identification
• Trapezoidal wire cross-section for increased load capacity within a compact footprint
• Chromium alloy steel construction for fatigue resistance under repeated cycling
• Maximum deflection load of 525.38 pounds (2,337 N) with 19 mm travel to solid
• Hole diameter of 25 mm and rod diameter of 12.5 mm for straightforward die pocket fitment
• Complies with ISO 10243 dimensional and performance standards

Compatibility

Designed as an ISO 10243-compliant Strong-duty die spring for use in standard die spring pockets with a 25 mm hole diameter and 12.5 mm rod diameter.

Installation Notes

Die spring replacement is performed by qualified tool and die makers with the press or tooling fully de-energized and locked out per LOTO procedures. Verify that the die pocket hole diameter and guide rod diameter match the spring dimensions before seating. Do not exceed the rated maximum deflection of 19 mm during operation, as over-compression accelerates fatigue failure. Inspect mating die components for wear or misalignment before installing a new spring.
