Associated Spring Raymond 104-516 Die Spring Red Medium Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 104-516 is a medium heavy-duty die spring designed for use in stamping dies, presses, and tooling applications where consistent force and reliable deflection are critical. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum load of 272.3 pounds at full deflection. The red color coding identifies it as a medium heavy-duty rating per standard die spring classifications. With a free length of 4 inches and a spring rate of 202 pounds per inch, it provides predictable performance across repeated compression cycles. Tool and die makers, machinists, and press maintenance technicians work with this component regularly in both production and repair settings.

This die spring fits applications requiring a 1-inch hole diameter and a 0.5-inch rod diameter. It is suited for use in metal stamping dies, injection mold tooling, and industrial press assemblies where controlled return force is needed. The 4-inch free length and 1.48-inch maximum deflection make it appropriate for medium-stroke tooling configurations. It is sold individually and is a direct replacement or spare for worn or broken die springs in existing tooling setups.

Key Features

• Trapezoidal wire cross-section provides higher load capacity compared to round wire springs of similar dimensions
• Chromium alloy steel construction resists fatigue and wear under repeated compression cycles
• Red color coding identifies medium heavy-duty duty rating for quick field identification
• Maximum deflection load of 272.3 pounds with a spring rate of 202 pounds per inch
• Meets ISO 9001:2008 and ISO/TS 16949:2009 quality standards; TUV Rheinland registered; ANAB accredited

Compatibility

Designed as an OEM-style replacement or spare die spring for industrial stamping dies, mold tooling, and press assemblies requiring a 1-inch hole diameter and 0.5-inch rod diameter with a 4-inch free length.

Installation Notes

Installation is performed by tool and die makers or press maintenance technicians. Always relieve all stored energy and lock out the press or tooling before removing or installing die springs. Confirm that the mating hole diameter and rod diameter match the spring specifications before seating the spring. Do not compress the spring beyond the rated maximum deflection of 1.48 inches to avoid permanent set or premature failure.
