Associated Spring Raymond 105-304 Heavy-duty Die Spring

Product Description

The ASSOCIATED SPRING RAYMOND 105-304 is a heavy-duty die spring designed for use in tooling, stamping, and press applications where consistent, high-load compression performance is required. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a rated spring rate of 424 pounds per inch and a maximum deflection load of 127.2 pounds at 0.3 inches of deflection. The gold color coding identifies it as a heavy-duty rated spring per industry die spring standards. It is installed by tool and die makers, machine maintenance technicians, and industrial equipment specialists working with punch and die assemblies.

This spring is suited for industrial press tooling, stamping dies, injection mold assemblies, and similar high-cycle compression applications. The compact 1-inch free length and 0.625-inch hole diameter make it appropriate for confined tooling cavities. The 0.34375-inch rod diameter rating ensures proper guidance when mounted on a center post. Applications span both light industrial and production manufacturing environments where repeatable load performance and dimensional consistency are critical.

Key Features

• Heavy-duty duty rating with gold color coding for fast visual identification in multi-spring assemblies
• Trapezoidal wire cross-section provides higher load capacity relative to round-wire springs of the same envelope size
• Chromium alloy steel construction for fatigue resistance in high-cycle press and tooling applications
• Spring rate of 424 pounds per inch with a maximum deflection load of 127.2 pounds at 0.3 inches
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems with TUV Rheinland registration and ANAB accreditation

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for heavy-duty stamping and press tooling assemblies requiring a 0.625-inch hole diameter, 0.34375-inch rod diameter, and 1-inch free length gold-coded heavy-duty spring.

Installation Notes

Die springs should be installed and serviced by qualified tool and die technicians or maintenance personnel familiar with press and stamping equipment. Always relieve all stored energy and lock out the press ram before removing or installing springs. Do not compress the spring beyond the rated maximum deflection of 0.3 inches, as over-compression will accelerate fatigue failure. Inspect springs for set, cracking, or discoloration at regular maintenance intervals.
