Gardner Spring 36112G Precision Compression Spring

Product Description

The GARDNER SPRING 36112G is a precision compression spring manufactured from music wire (AISI 302, ASTM A228, ASTM A313). It features a 0.6000-inch outside diameter, a free length of 1.25 inches, and a wire diameter of 0.0720 inches. The spring delivers a rate of 45 pounds per inch and handles a maximum work load of 30 pounds (133.45 N). The closed and ground end type provides consistent seating and uniform load distribution. This spring is suited for use in mechanical assemblies, HVAC equipment components, industrial tooling, and precision instrument applications where repeatable force characteristics are required.

This spring is a fit for applications requiring a compact, high-cycle compression element within a 5/8-inch (0.6250-inch) hole diameter. It is commonly specified in residential and light commercial mechanical systems, valve assemblies, and general industrial equipment. The plain silver finish and music wire construction make it appropriate for dry or lightly lubricated environments where corrosion exposure is minimal. Technicians and assemblers across HVAC, plumbing, and general mechanical trades regularly use springs of this specification for OEM replacement and custom assembly work.

Compatibility

Designed as an OEM-style precision compression spring for mechanical assemblies requiring a 0.6000-inch outside diameter and 1.25-inch free length with a 45-pound-per-inch spring rate.

Installation Notes

Installation is typically performed by qualified mechanical technicians or assemblers familiar with spring-loaded component systems. Verify the mating bore diameter and seating surfaces are clean and free of burrs before installation. Do not compress the spring beyond its solid height of 0.5960 inches, as permanent set or damage may result. Follow applicable equipment manufacturer guidelines and relevant industry codes when integrating into pressurized or load-bearing assemblies.
