Gardner Spring 36020G Precision Compression Spring

Product Description

The GARDNER SPRING 36020G is a precision compression spring manufactured from music wire with a plain silver finish. It features a 0.18 inch outside diameter and a free length of 0.875 inches, making it suited for compact mechanical assemblies where consistent load response is required. The spring delivers a maximum work load of 6.75 pounds at a spring rate of 15 pounds per inch. With closed and ground ends, it seats flat against mating surfaces, reducing lateral deflection and improving load uniformity. Maintenance technicians, mechanical assemblers, and OEM equipment manufacturers typically install this type of spring in precision motion or actuation mechanisms.

This spring fits applications where tight dimensional tolerances and repeatable spring force are critical. Common uses include control linkages, valve actuators, instrument mechanisms, and small-bore mechanical assemblies. The 0.026 inch wire diameter and 0.391 inch solid height allow integration into space-constrained designs. The plain finish is appropriate for dry or lightly lubricated environments. This part is sold in packages of 5 with a minimum order quantity of 1 package.

Key Features

• Closed and ground ends for flat seating and reduced lateral deflection
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Spring rate of 15 pounds per inch with a 6.75 pound maximum work load
• Outside diameter of 0.18 inches fits holes up to 0.187 inches in diameter
• Solid height of 0.391 inches limits compression travel in tight assemblies
• Plain silver finish suitable for dry and light-lubrication environments

Compatibility

Designed as a precision replacement or OEM-specification compression spring for compact mechanical assemblies requiring a 0.18 inch outside diameter and 0.875 inch free length with closed and ground ends.

Installation Notes

Compression springs of this type are installed by mechanical assemblers and maintenance technicians working on precision equipment. Always relieve any stored mechanical or pneumatic energy in the assembly before removing or installing springs. Verify that the mating bore or guide pin dimensions align with the specified hole diameter of 0.187 inches and wire size of 0.026 inches to ensure proper fitment and avoid coil binding. Do not stretch or over-compress the spring beyond its solid height during installation.
