Associated Spring Raymond 103-510 Die Spring Medium Duty Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-510 is a medium-duty die spring designed for use in stamping dies, punch presses, and tooling fixtures where consistent, repeatable force is required. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 250 pounds and a spring rate of 209 pounds per inch. The blue color coding identifies its medium-duty rating, making it straightforward to sort and replace in multi-spring tooling setups. It is installed by tool and die makers, press operators, and maintenance technicians working in metal fabrication and industrial manufacturing environments.

This die spring fits standard tooling applications calling for a 1-inch hole diameter and a 0.5-inch rod diameter. With a free length of 2.5 inches and a maximum deflection of 1.25 inches, it suits a wide range of die and fixture designs where controlled compression travel is critical. The trapezoidal wire geometry allows higher load capacity within the same envelope compared to round-wire springs of similar dimensions, making it a practical choice for medium-load tooling applications in production and job-shop settings.

Key Features

• Medium-duty blue color coding for quick identification and replacement in multi-spring tooling setups
• Chromium alloy steel construction for durability under repeated compression cycles
• Trapezoidal wire shape provides higher load capacity within a compact envelope
• 250-pound maximum deflection load with a consistent spring rate of 209 pounds per inch
• Manufactured to ISO 9001:2008 and ISO/TS 16949:2009 standards with TUV Rheinland registration

Compatibility

Designed as a standard-dimensioned die spring for tooling applications requiring a 1-inch hole diameter and a 0.5-inch rod diameter with a 2.5-inch free length in medium-duty configurations.

Installation Notes

Die springs should be installed by qualified tool and die technicians following the press or die manufacturer's load and deflection specifications. Always de-energize and lock out the press before servicing or replacing springs. Do not exceed the rated maximum deflection of 1.25 inches, as over-compression will reduce service life. Inspect seating surfaces for wear or debris before installation to ensure even load distribution.
