Associated Spring Raymond 105-310 Heavy-duty Die Spring

Product Description

The ASSOCIATED SPRING RAYMOND 105-310 is a heavy-duty die spring engineered for high-load compression applications in industrial tooling and stamping dies. It features a trapezoidal wire shape that delivers greater load capacity compared to round-wire springs of the same outer dimensions. With a 5/8 inch hole diameter, an 11/32 inch rod diameter, and a 2-1/2 inch free length, this spring is sized for precision fit in standard die sets. It carries a maximum deflection load of 127.5 pounds and a spring rate of 170 pounds per inch. The gold color coding identifies the heavy-duty duty rating at a glance, consistent with ISO die spring standards.

This die spring is intended for use in metal stamping dies, punch press tooling, mold clamping assemblies, and similar industrial compression spring applications. It is installed by tool and die makers, press room technicians, and maintenance machinists working on production tooling. Its compact free length of 2-1/2 inches and precise rod and hole dimensions make it suitable for close-tolerance die spring pockets where consistent force and deflection are critical.

Key Features

• Heavy-duty duty rating with gold color coding for quick identification
• Trapezoidal wire shape for higher load capacity per unit size
• 127.5 pound maximum deflection load with 0.75 inch maximum deflection
• Spring rate of 170 pounds per inch for predictable, linear force output
• Chromium alloy steel construction for fatigue resistance in cyclic loading
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit die spring for heavy-duty compression applications requiring a 5/8 inch hole diameter, 11/32 inch rod diameter, and 2-1/2 inch free length in standard industrial die sets.

Installation Notes

Die springs should be installed by qualified tool and die or maintenance personnel with the press or tooling fully de-energized and in the locked-out, tagged-out condition per OSHA lockout/tagout procedures. Verify that the spring pocket depth and rod clearance match the specified hole and rod diameters before seating the spring. Do not compress the spring beyond its rated maximum deflection of 0.75 inch, as exceeding this value will accelerate fatigue failure. Inspect springs regularly for signs of set, cracking, or corrosion and replace as a set when refurbishing die tooling.
