Gardner Spring 36284G Precision Compression Spring

Product Description

The GARDNER SPRING 36284G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) with a plain silver finish. It measures 0.18 inches outside diameter and 1.25 inches free length, with a wire diameter of 0.0319 inches. The spring delivers a rate of 23.5 pounds per inch and supports a maximum work load of 12 pounds. Closed and ground ends provide consistent seating and stable load transfer. This part is suited for OEM assemblies, mechanical subcomponents, and precision instrumentation where repeatable spring force and dimensional accuracy are required.

This compression spring is used across a wide range of light-duty mechanical assemblies in HVAC equipment, plumbing valve components, electrical relay housings, and general industrial applications. The compact 0.18-inch OD and 1.25-inch free length make it appropriate for tight-clearance bores and small actuator mechanisms. It is typically installed by mechanical technicians, OEM assembly lines, or field service technicians replacing worn or fatigued springs in control components and valve bodies.

Key Features

• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Spring rate of 23.5 pounds per inch for predictable, linear load response
• Maximum work load of 12 pounds (55.60 N)
• Closed and ground ends for flat, consistent seating surface
• Solid height of 0.739 inches supports controlled deflection range
• Plain silver finish - no coating to affect dimensional tolerances in tight bores

Compatibility

Designed as a precision OEM-style compression spring for use in mechanical assemblies requiring a 0.18-inch outside diameter and 1.25-inch free length spring with closed and ground ends.

Installation Notes

Installation typically requires no special tools beyond the assembly hardware of the host component. Before servicing any assembly containing this spring, de-energize all electrical circuits and relieve any system pressure per applicable codes. Confirm the replacement spring seats flat against both mating surfaces before reassembling the component. Inspect the bore or housing for wear that could cause the spring to cock or bind under load.
