Associated Spring Raymond 106-840 Die Spring 2in Hole 10in

Product Description

The ASSOCIATED SPRING RAYMOND 106-840 is a heavy-load die spring engineered for use in stamping dies, punch press tooling, and other industrial compression spring applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum load of 2,100 pounds at full deflection and a spring rate of 884 pounds per inch. The green color coding identifies it as a heavy-duty load class per standard die spring classification. This spring is installed and serviced by toolmakers, die setters, and maintenance machinists working in metal fabrication and manufacturing environments.

This spring is suited for die sets and press tooling requiring a 2 inch hole diameter and 1 inch rod diameter with a free length of 10 inches. The 2.5 inch maximum deflection allows controlled, repeatable compression strokes in high-cycle stamping operations. It is also used in jig and fixture applications, injection mold tooling, and other precision compression spring positions where consistent load characteristics and dimensional accuracy are critical.

Key Features

• Chromium alloy steel construction for durability under high-cycle fatigue loading
• Trapezoidal wire cross-section maximizes load capacity relative to spring envelope
• Green color designation indicates heavy-duty load class per international die spring standards
• 884 pounds per inch spring rate provides predictable, linear compression force
• 2,100 pound maximum deflection load suitable for demanding press tooling applications
• Certified to ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland quality standards

Compatibility

Designed for use in standard die spring positions with a 2 inch hole diameter and 1 inch rod diameter. Fits tooling applications requiring a 10 inch free length heavy-duty compression spring in the green load class.

Installation Notes

Installation is typically performed by toolmakers or die maintenance technicians. The press or machine must be fully de-energized and locked out before any die spring replacement. Verify that the housing bore and guide rod dimensions match the spring specifications before seating the spring. Do not compress the spring beyond the rated 2.5 inch maximum deflection, as exceeding this limit will cause permanent set or premature failure.
