Gardner Spring 36281G Precision Compression Spring

Product Description

The GARDNER SPRING 36281G is a precision compression spring manufactured from music wire to tight dimensional tolerances. It measures 0.18 inches in outside diameter with a free length of 0.75 inches and a wire diameter of 0.032 inches. The spring delivers a rated spring rate of 41 pounds per inch and handles a maximum work load of 12 pounds. End type is closed and ground, which provides flat, stable seating surfaces. Solid height is 0.45 inches. This spring is suited for light-duty mechanical assemblies requiring consistent, repeatable force in a compact form factor. Machinists, maintenance technicians, and mechanical assemblers are the typical installers.

The GARDNER SPRING 36281G is used in small mechanical and electromechanical assemblies across HVAC, plumbing hardware, fluid control valves, and general industrial equipment. Its compact 0.18-inch OD makes it appropriate for applications with tight radial clearances, such as valve stems, actuator mechanisms, and instrument components. The hole diameter for this spring is 0.188 inches, providing guidance for pin or mandrel mounting. It is sold in packages of 5 units with a minimum order quantity of 1 package.

Key Features

• Closed and ground ends for flat, stable seating and accurate load transfer
• Spring rate of 41 pounds per inch for consistent, predictable deflection behavior
• Maximum work load of 12 pounds (55.60 newtons)
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Outside diameter of 0.18 inches fits applications with tight radial clearances
• Solid height of 0.45 inches limits compression travel in confined assemblies

Compatibility

Designed as an OEM-style replacement or service part for small mechanical assemblies requiring a precision compression spring with a 0.18-inch outside diameter and 0.75-inch free length. Verify spring rate, solid height, and end type against the application requirement before installation.

Installation Notes

Installation of compression springs should be performed by qualified mechanical or maintenance technicians familiar with spring-loaded assemblies. Relieve all system pressure and de-energize any connected actuators or valve assemblies before removing or installing the spring. Confirm mandrel or pin diameter does not exceed the 0.188-inch hole diameter to avoid binding. Do not compress the spring beyond its solid height of 0.45 inches during assembly or testing.
