Gardner Spring 36545G Precision Compression Spring

Product Description

The GARDNER SPRING 36545G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) for consistent, repeatable performance under cyclic load. The spring measures 0.72 inches in outside diameter with a free length of 2.5 inches and a wire diameter of 0.0551 inches. It delivers a spring rate of 6.6 pounds per inch and supports a maximum work load of 13 pounds (57.83 N). Closed and ground ends provide stable, flat seating and accurate load transfer. This part is installed by maintenance technicians, mechanical assemblers, and trade professionals working on HVAC equipment, plumbing components, or general mechanical assemblies requiring a precisely rated compression spring.

This spring is suited for light-duty to medium-duty compression applications in residential and commercial mechanical systems. Its music wire construction and plain finish make it appropriate for dry or lightly lubricated environments where corrosion exposure is limited. The closed and ground end configuration ensures consistent contact with mating surfaces, making it a reliable drop-in component for OEM repair or custom assembly work. Packaged in quantities of five, it is available for single-unit minimum order quantities.

Key Features

• Closed and ground ends for flat, stable seating and accurate load distribution
• Spring rate of 6.6 pounds per inch for predictable deflection behavior
• Maximum work load of 13 pounds (57.83 N)
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Outside diameter of 0.72 inches fits a 0.75-inch hole diameter clearance
• Solid height of 0.516 inches allows compact installation in tight assemblies

Compatibility

Designed as a precision OEM-style replacement or assembly component for mechanical systems requiring a compression spring with a 0.72-inch outside diameter, 2.5-inch free length, and 6.6 pounds-per-inch spring rate.

Installation Notes

Install by qualified mechanical or trade technicians following applicable equipment service procedures. De-energize and lock out all energy sources before accessing any spring-loaded assembly. Verify that the mating bore or rod diameter is compatible with the 0.75-inch hole diameter and 0.72-inch outside diameter before installation. Do not compress the spring beyond its solid height of 0.516 inches during service or testing.
