Associated Spring Raymond 104-308 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-308 is a medium heavy-duty die spring designed for use in stamping dies, punch presses, and tooling fixtures that require consistent, reliable return force. It features a 0.625-inch hole diameter, an 11/32-inch rod diameter, and a 2-inch free length. The trapezoidal wire shape maximizes load capacity within a compact envelope. Constructed from chromium alloy steel, the 104-308 delivers a spring rate of 155 pounds per inch and a maximum deflection load of 109.5 pounds at 0.74 inches of travel. The red color coding identifies this unit as a medium heavy-duty rating per industry convention.

This die spring is suited for industrial tooling applications including metal stamping dies, injection mold tooling, and hydraulic press fixtures. It is appropriate wherever a compact, high-cycle-capable compression spring is required to maintain consistent force during repeated deflection. Licensed toolmakers, die setters, and maintenance technicians working in fabrication and manufacturing environments are the primary installers. The 2-inch free length makes it adaptable to a range of standard die set configurations.

Key Features

• Trapezoidal wire cross-section increases load capacity compared to round wire springs of the same envelope size
• Chromium alloy steel construction provides fatigue resistance under high-cycle tooling conditions
• 155 lb per inch spring rate with a 109.5 lb maximum deflection load
• 0.74-inch maximum deflection travel
• Red color code identifies medium heavy-duty duty rating for fast identification during die setup
• ANAB Accredited and ISO 9001:2008 Certified; ISO/TS 16949:2009 Certified; TUV Rheinland Registered

Compatibility

Designed as a standard replacement or new-installation die spring for tooling fixtures requiring a 0.625-inch hole diameter, 11/32-inch rod diameter, 2-inch free length, and medium heavy-duty duty rating.

Installation Notes

Die springs are typically installed and replaced by toolmakers or die maintenance technicians. Before servicing a die set, lock out and tag out all press energy sources per OSHA lockout/tagout procedures. Inspect the mating hole and guide rod dimensions against the spring specifications before installation to prevent side loading. Never compress a die spring beyond its rated maximum deflection, as overtravel can cause permanent set or fatigue failure.
