Associated Spring Raymond 105-620 Die Spring Heavy-duty Gold

Product Description

The ASSOCIATED SPRING RAYMOND 105-620 is a heavy-duty die spring designed for use in stamping dies, press tooling, and industrial machinery applications. It features a 1-1/4 inch hole diameter, a 5/8 inch rod diameter, and a 5 inch free length. Constructed from chromium alloy steel with a trapezoidal wire profile, this spring delivers a rated spring rate of 530 pounds per inch and a maximum deflection load of 795 pounds at 1.5 inches of travel. The gold color coding identifies the heavy-duty load class, following standard die spring classification conventions. Licensed tool and die makers and industrial maintenance technicians are the primary installers.

This die spring is suited for heavy-duty compression applications in metal stamping dies, injection molds, and automated press machinery. Its trapezoidal wire cross-section allows higher load capacity in a compact envelope compared to round-wire springs of similar outer dimensions. The 5 inch free length and defined deflection characteristics make it a fit for both new tooling builds and replacement applications in existing die sets requiring a heavy-duty gold-class spring.

Key Features

• Heavy-duty duty rating with gold color coding for quick load-class identification
• Trapezoidal wire shape provides higher load density relative to round-wire alternatives
• Chromium alloy steel construction for fatigue resistance under cyclic loading
• 530 pounds per inch spring rate with 795 lb maximum deflection load
• 1.5 inches maximum deflection at full rated load
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a heavy-duty die spring replacement for industrial press tooling and stamping die applications requiring a 1-1/4 inch hole diameter, 5/8 inch rod diameter, and 5 inch free length in the gold heavy-duty load class.

Installation Notes

Die spring installation and replacement is typically performed by tool and die makers or qualified industrial maintenance personnel. De-energize and lock out all press and tooling equipment before removing or installing springs. Verify that the mating die set pocket and guide rod dimensions match the spring hole diameter and rod diameter to ensure proper seating and alignment. Do not compress the spring beyond the rated maximum deflection of 1.5 inches, as over-compression will shorten fatigue life and may cause failure.
