Associated Spring Raymond 104-620 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-620 is a medium heavy-duty die spring engineered for use in stamping dies, press tooling, and industrial machinery applications. It features a trapezoidal wire shape wound from chromium alloy steel, which provides consistent force output and extended cycle life under repeated compression. The spring measures 1-1/4 inches in hole diameter, 5/8 inches in rod diameter, and 5 inches in free length. With a maximum deflection load of 536.5 pounds and a maximum deflection of 1.85 inches, it is sized for demanding production tooling where reliable return force is critical. Licensed tool and die makers and industrial maintenance technicians are the primary installers.

This die spring is suited for press dies, injection mold tooling, jigs, and fixtures in both manufacturing and industrial maintenance environments. The red color coding identifies it as a medium heavy-duty spring per standard die spring classification conventions. It is applicable in settings where controlled compression and consistent spring rate are required across high-cycle operations. A spring rate of 300 pounds per inch allows predictable force calculations during tooling design.

Key Features

• Trapezoidal wire cross-section for higher load capacity versus round-wire springs of comparable size
• Chromium alloy steel construction for fatigue resistance in high-cycle press applications
• Medium heavy-duty duty rating with a 300 lb per inch spring rate
• Maximum deflection load of 536.5 pounds at 1.85 inches of travel
• Red color coding for quick duty-rating identification in the field
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or new-installation die spring for standard die spring bores accepting a 1-1/4 inch outer diameter and a 5/8 inch rod diameter in medium heavy-duty press tooling applications.

Installation Notes

Die springs are installed and replaced by tool and die makers or qualified industrial maintenance personnel. Always fully de-energize and lock out the press before removing or installing die springs. Confirm that the bore diameter, rod diameter, free length, and duty rating of the replacement spring match the tooling design specifications before installation. Do not compress a die spring beyond its rated maximum deflection, as overcompression causes permanent set and premature failure.
