Associated Spring Raymond 104-606 Die Spring Red Medium Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 104-606 is a medium heavy-duty die spring designed for use in stamping dies, punch presses, and industrial tooling applications. It features a 1-1/4 inch hole diameter, a 5/8 inch rod diameter, and a free length of 1-1/2 inches. Constructed from chromium alloy steel with a trapezoidal wire profile, this spring delivers a maximum deflection load of 634.9 pounds at a maximum deflection of 0.56 inches. The red color coding identifies its medium heavy-duty classification, making it easy to sort and replace in multi-spring tooling setups. It is sold individually with a minimum order quantity of one.

This die spring is suited for industrial press tooling, injection mold assemblies, and heavy-duty mechanical fixtures that require consistent, repeatable spring force over extended cycles. The trapezoidal wire cross-section provides higher load capacity in a compact envelope compared to round-wire designs, making it appropriate for tight-tolerance tooling where space is limited. Maintenance machinists, toolmakers, and die setters are the primary installers of this component.

Key Features

• 1-1/4 inch hole diameter and 5/8 inch rod diameter for standard die post fitment
• 1-1/2 inch free length in a compact form factor
• Maximum deflection load of 634.9 pounds with a spring rate of 1,144 pounds per inch
• Maximum deflection of 0.56 inches for controlled stroke applications
• Trapezoidal wire shape maximizes load density within the spring envelope
• Chromium alloy steel construction for durability under repetitive cycling
• Red color coding identifies medium heavy-duty duty rating at a glance

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard die spring applications requiring a 1-1/4 inch hole diameter, 5/8 inch rod diameter, and 1-1/2 inch free length in medium heavy-duty configurations.

Installation Notes

Die spring replacement is performed by qualified toolmakers or maintenance machinists with the press or tooling fully de-energized and locked out per applicable OSHA lockout/tagout procedures. Verify that the rod and bore diameters in the tooling assembly match the spring specifications before installation. Do not compress the spring beyond its rated maximum deflection of 0.56 inches, as over-compression will shorten service life and may cause permanent set. Inspect the seating surfaces for wear or debris before installing the new spring.
