Associated Spring Raymond 106-307 Die Spring Extra Heavy-duty

Product Description

The ASSOCIATED SPRING RAYMOND 106-307 is an extra heavy-duty die spring designed for use in stamping dies, punch presses, and other high-load tooling applications. It features a trapezoidal wire shape that provides greater load capacity compared to standard round-wire springs, making it well suited for demanding industrial press environments. With a maximum deflection load of 140 pounds, a spring rate of 310 pounds per inch, and a free length of 1.75 inches, this green-coded spring delivers consistent, repeatable force output across its service life. It is manufactured from chromium alloy steel for durability under cyclic compression loads.

This die spring is intended for use in metal stamping, forming, and die-tooling applications where controlled return force is required. The green color coding indicates an extra heavy-duty duty rating per standard die spring classifications, allowing toolmakers and maintenance technicians to quickly identify and replace springs to the correct load specification. It fits applications requiring a 0.625-inch hole diameter and an 11/32-inch rod diameter, and is appropriate for both OEM tooling builds and replacement maintenance in production environments.

Key Features

• Extra heavy-duty duty rating with green color coding for quick identification
• Trapezoidal wire shape provides higher load capacity than round-wire alternatives
• 140-pound maximum deflection load with a spring rate of 310 pounds per inch
• Maximum deflection of 0.44 inches keeps stroke within safe operating limits
• Chromium alloy steel construction for long service life under cyclic compression
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a replacement or OEM-spec die spring for tooling applications requiring a 0.625-inch hole diameter, an 11/32-inch rod diameter, and a 1.75-inch free length in an extra heavy-duty load class.

Installation Notes

Installation is typically performed by toolmakers or die maintenance technicians during press tooling setup or scheduled maintenance. Always de-energize and lock out the press before removing or installing die springs. Ensure the mating hole and rod dimensions match the spring specifications before installation, and never compress the spring beyond its rated maximum deflection to avoid permanent set or premature failure.
