Associated Spring Raymond 104-105 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-105 is a medium heavy-duty die spring engineered for use in stamping dies, punch presses, and tooling fixtures. It features a trapezoidal wire shape that delivers higher load capacity and longer fatigue life compared to round-wire springs of the same size. The hole diameter measures 0.375 inches, the rod diameter measures 0.1875 inches, and the free length is 1.25 inches. Maximum deflection load is 33.8 pounds at a maximum deflection of 0.46 inches, with a spring rate of 73 pounds per inch. This spring is color-coded red per industry convention to identify its medium heavy-duty duty rating. Installation is typically performed by tool and die makers, press maintenance technicians, and industrial maintenance professionals.

This die spring is suited for compact tooling applications where space is limited but consistent, reliable spring force is required. The red color coding allows for quick identification and replacement in multi-spring die sets. Typical applications include stripper plates, pressure pads, and return mechanisms in stamping and forming dies. The chromium alloy steel construction provides the strength and wear resistance demanded by repetitive high-cycle press operations in both production and maintenance shop environments.

Key Features

• Trapezoidal wire cross-section for higher load density and extended fatigue life versus round-wire designs
• Medium heavy-duty rating, color-coded red for fast field identification
• Spring rate of 73 pounds per inch for consistent, predictable force output
• Chromium alloy steel construction for strength and corrosion resistance in industrial environments
• Manufactured to ISO 9001:2008 and ISO/TS 16949:2009 quality standards with TUV Rheinland registration and ANAB accreditation

Compatibility

Designed as a standard-dimension die spring for use in stamping dies, punch presses, and tooling fixtures requiring a 0.375-inch hole diameter, 0.1875-inch rod diameter, and 1.25-inch free length with a medium heavy-duty load rating.

Installation Notes

Die springs of this type are installed by tool and die makers or press maintenance technicians. Always de-energize and lock out the press before servicing any tooling components. Do not compress the spring beyond the rated maximum deflection of 0.46 inches, as over-compression reduces fatigue life and can cause premature failure. Inspect seating surfaces for burrs or damage before installation to ensure proper load distribution.
