Associated Spring Raymond C01800140380M Compression Spring

Product Description

The ASSOCIATED SPRING RAYMOND C01800140380M is a precision compression spring manufactured from carbon steel music wire. It features a 0.18-inch outside diameter and a free length of 0.38 inches, making it suited for compact mechanical assemblies where space is limited. The spring carries a maximum work load of 0.84 pounds (3.74 N) and a spring rate of 3.9 inch-pounds per inch. Square end type provides stable seating against mating surfaces. This part is handled by mechanical assemblers, maintenance technicians, and precision equipment service professionals working in tight-tolerance applications.

This compression spring is used in small mechanical devices, instrumentation, electronics assemblies, and light-duty industrial equipment where a compact, precision-wound spring is required. The plain finish and silver color are consistent with standard uncoated music wire stock. Its solid height of 0.09 inches allows for significant compression travel relative to its free length, which is useful in spring-loaded mechanisms that require consistent return force in a minimal footprint.

Key Features

• Outside diameter of 0.18 inches fits a 0.15-inch hole diameter clearance
• Free length of 0.38 inches with a solid height of 0.09 inches
• Spring rate of 3.9 inch-pounds per inch for predictable load-deflection behavior
• Maximum work load of 0.84 pounds (3.74 N)
• Meets ASTM A228 and AMS 5112 standards for music wire quality
• Square end type for flat, stable seating

Compatibility

Designed as a precision compression spring suitable for compact mechanical assemblies, instrumentation, and light-duty industrial applications requiring an 0.18-inch OD music wire spring.

Installation Notes

Installation is typically performed by mechanical technicians or assemblers using standard hand tools. Ensure the mating bore or housing does not exceed the recommended hole diameter to maintain proper spring alignment and prevent buckling. Avoid over-compressing the spring beyond its solid height during installation, as this can permanently set the coils and degrade performance. Verify load and deflection requirements against application specs before installation.
