Associated Spring Raymond 104-840 Die Spring 2in X 10in Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-840 is a heavy-duty die spring engineered for use in stamping dies, press tooling, and industrial machinery applications requiring consistent, reliable return force. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a rated spring rate of 260 pounds per inch and a maximum deflection load of 962 pounds at full compression. The red color coding identifies it as a heavy-load series spring. With a 2-inch hole diameter, 1-inch rod diameter, and 10-inch free length, it is sized for mid-to-large press die setups. Installation and replacement are typically performed by toolroom machinists or maintenance technicians in manufacturing environments.

This die spring is suited for use in progressive dies, compound dies, stripper plate assemblies, and general press tooling where controlled force and predictable deflection are required. The 3.7-inch maximum deflection rating allows for substantial stroke travel without exceeding design load limits. Its chromium alloy steel construction provides resistance to fatigue and high-cycle wear common in production stamping operations. The 10-inch free length accommodates tooling configurations that require longer spring pockets or extended travel ranges.

Key Features

• Trapezoidal wire cross-section provides higher load capacity in the same envelope compared to round wire springs
• Spring rate of 260 pounds per inch delivers predictable, linear force across the deflection range
• Maximum deflection load of 962 pounds supports heavy stripper and ejector plate applications
• Chromium alloy steel construction resists fatigue under high-cycle press conditions
• Red color coding identifies the heavy-load series for fast visual identification during die maintenance
• Meets ISO 9001 and ISO/TS 16949 quality standards with TUV Rheinland registration

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for industrial press tooling and stamping die assemblies requiring a 2-inch hole diameter, 1-inch rod diameter, and 10-inch free length in the heavy-load red series.

Installation Notes

Die springs should be installed and replaced by qualified toolroom personnel or maintenance machinists familiar with press die construction. Always de-energize and lock out the press before accessing the die set. Inspect the spring pocket depth and rod clearance to confirm dimensional compatibility before installation. Do not compress the spring beyond the rated maximum deflection of 3.7 inches, as over-compression accelerates fatigue failure and can cause uncontrolled spring fracture.
