Associated Spring Raymond 103-514 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 103-514 is a medium-duty die spring designed for use in stamping dies, punch press tooling, and other high-cycle industrial press applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers consistent force across its deflection range. The spring has a 1 inch hole diameter, accepts a 1/2 inch guide rod, and has a free length of 3-1/2 inches. At full rated deflection of 1.75 inches, it generates a maximum load of 262.5 pounds. The blue color coding identifies it as a medium-duty spring per standard die spring classification conventions. Installation is typically performed by tool and die makers or maintenance machinists.

This die spring is suited for use in progressive dies, compound dies, and stripper plate assemblies in metal stamping and fabrication shops. It fits into standard die sets wherever a 1 inch bore is machined to receive the spring body, with a 1/2 inch guide rod keeping it aligned during compression cycles. Medium-duty blue springs are a common general-purpose choice where moderate return force and long cycle life are required without the higher loads of a heavy-duty spring.

Key Features

• Trapezoidal wire cross-section provides higher load capacity per unit of free length compared to round wire springs
• Chromium alloy steel construction for durability in high-cycle press tooling environments
• 1 inch hole diameter with 1/2 inch rod diameter for positive alignment on guide rods
• Maximum deflection load of 262.5 pounds at 1.75 inches of travel
• Spring rate of 145 pounds per inch for predictable, linear force output
• Blue color coding identifies medium-duty rating at a glance during tooling setup and maintenance

Compatibility

Designed as an OEM-style replacement or new installation die spring for standard industrial die sets requiring a 1 inch bore, 1/2 inch guide rod, and 3-1/2 inch free length in a medium-duty blue classification.

Installation Notes

Die springs of this type are installed by tool and die makers or maintenance personnel familiar with press tooling. Always relieve all press pressure and lock out the ram before removing or replacing springs in a die set. Inspect the guide rod and bore for wear or misalignment before installing a replacement spring, as a bent or oversized rod accelerates fatigue. Do not compress the spring beyond its rated maximum deflection of 1.75 inches in service.
