Associated Spring Raymond 103-248 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-248 is a medium-duty die spring engineered for use in stamping dies, molds, and other high-cycle industrial tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force characteristics and long service life under repetitive compression loads. It features a 0.5 inch hole diameter, a 9/32 inch rod diameter, a 12 inch free length, and a maximum deflection of 6 inches. The blue color coding identifies its medium-duty rating per industry convention. With a maximum deflection load of 42 pounds and a spring rate of 7 pounds per inch, it is sized for applications where controlled, predictable force is essential. Licensed technicians, toolmakers, and maintenance personnel install this spring as an OEM-style or replacement component.

This spring is suited for use in punch press tooling, injection molds, and die sets where a guided rod and bore configuration is required. The 9/32 inch rod diameter and 0.5 inch hole diameter allow proper guidance within a standard die set boring without play. The 12 inch free length accommodates tooling assemblies requiring extended travel or pre-load range. Medium-duty classification makes it appropriate for moderate-cycle production tooling rather than extreme-duty or light-duty applications. It is installed by toolmakers, press technicians, and industrial maintenance professionals in both OEM and aftermarket tooling assemblies.

Key Features

• Chromium alloy steel construction for high-cycle fatigue resistance
• Trapezoidal wire cross-section increases load capacity relative to round wire designs
• Blue color coding identifies medium-duty rating per industry-standard classification
• Maximum deflection load of 42 pounds with a spring rate of 7 pounds per inch
• 6 inch maximum deflection for extended travel range in deep die sets
• Meets ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland quality standards

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for standard guided die sets and tooling assemblies requiring a 0.5 inch bore diameter and 9/32 inch rod diameter with a 12 inch free length in the medium-duty blue classification.

Installation Notes

Die spring replacement and installation should be performed by qualified toolmakers or industrial maintenance technicians with the press or tooling equipment fully de-energized and locked out per OSHA lockout/tagout requirements. The spring must be properly guided on the rod and within the bore to prevent buckling under load. Never compress a die spring beyond its rated maximum deflection, as overtravel causes permanent set and rapid fatigue failure. Inspect the mating rod and bore surfaces for wear or damage before installing a new spring.
