Gardner Spring 36605GS Precision Compression Spring

Product Description

The GARDNER SPRING 36605GS is a precision compression spring manufactured from stainless steel and designed for applications that demand consistent, repeatable force across a defined travel range. With an outside diameter of 0.845 inches and a free length of 3 inches, this spring delivers a maximum work load of 41 pounds and a spring rate of 20 pounds per inch. The closed and ground end configuration ensures stable, square seating against mating surfaces, reducing lateral deflection during compression. Machinists, maintenance technicians, and mechanical assembly professionals install this type of spring in equipment requiring controlled resistance and reliable cycling over time.

This compression spring suits a wide range of industrial and mechanical assembly scenarios where precise load and rate tolerances are required. The 0.845 inch outside diameter is sized to fit into a bore or housing up to 0.875 inches in diameter, making it appropriate for valve assemblies, actuator mechanisms, tool and die setups, and general-purpose mechanical equipment. The stainless steel construction makes it a practical choice in environments where corrosion resistance or contact with moisture is a concern.

Key Features

• Closed and ground ends provide flat, stable seating and minimize tilt under load
• Stainless steel construction (AISI 302) resists corrosion in wet or chemically exposed environments
• Maximum work load of 41 pounds supports moderate-duty compression applications
• Spring rate of 20 pounds per inch delivers predictable, linear force response
• 0.0909 inch wire diameter and 1.185 inch solid height confirm tight manufacturing tolerances
• Meets AISI 302, ASTM A228, and ASTM A313 material standards

Compatibility

Designed as a precision-grade replacement or original-equipment compression spring for mechanical assemblies requiring an 0.845 inch outside diameter, 3 inch free length, and 41 pound maximum work load in a closed and ground end configuration.

Installation Notes

Installation is typically performed by mechanical technicians or maintenance personnel familiar with spring-loaded assemblies. Depressurize or de-energize the assembly completely before removing or installing any compression spring. Verify that the mating bore diameter does not exceed 0.875 inches and that the seating surfaces are clean and flat to prevent cocking or uneven loading. Never compress a spring beyond its solid height, as doing so can cause permanent set and compromise load performance.
