Gardner Spring MC040-0300-M Precision Compression Spring

Product Description

The GARDNER SPRING MC040-0300-M is a precision compression spring manufactured from stainless steel with a plain finish. It features a 0.217-inch outside diameter and a 1.181-inch free length, making it a compact, high-tolerance component suited for light-load mechanical assemblies. The spring carries a maximum work load of 8.04 pounds and a spring rate of 1.89 inch-pounds per inch, with closed ends for stable seating. It is intended for use by mechanical engineers, field technicians, and trade professionals requiring consistent, repeatable spring performance in tight spaces.

This spring is well suited for light-duty actuation, valve, or mechanism applications where dimensional precision and material consistency are critical. The stainless steel construction supports use in environments where corrosion resistance is a factor. With a solid height of 0.305 inches and a wire diameter of 0.0197 inches, it fits into compact assemblies requiring predictable deflection behavior. It is sold in packages of five with a minimum order quantity of one package.

Compatibility

Designed as a precision replacement or OEM-specification compression spring for light-load mechanical, valve, and actuation assemblies requiring a 0.217-inch outside diameter closed-end stainless steel spring.

Installation Notes

Installation of compression springs should be performed with the actuating assembly fully de-energized and depressurized. Verify the spring pocket or guide diameter and solid height clearance against assembly drawings before installation. Use appropriate hand tools or spring insertion tools to avoid overcompressing the spring beyond its solid height during assembly. Consult applicable mechanical or equipment service documentation for torque and fastener specifications related to the surrounding assembly.
