Gardner Spring 36010G Precision Compression Spring

Product Description

The GARDNER SPRING 36010G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) with a plain silver finish. It features a 0.18-inch outside diameter, a 0.50-inch free length, and a 0.0161-inch wire diameter. The spring delivers a rated spring rate of 4.5 pounds per inch and a maximum working load of 1.5 pounds. With closed and ground ends, it provides consistent seating and predictable load distribution. Maintenance technicians, machine builders, and trade professionals install this spring in precision mechanical assemblies requiring reliable, repeatable compression force in a compact form factor.

This spring is suited for use in light-duty mechanical, pneumatic, and instrument-grade assemblies where tight dimensional tolerances are required. Its small outside diameter and short free length make it appropriate for applications in HVAC actuator mechanisms, valve assemblies, precision tooling, and similar equipment where consistent spring force and accurate solid height control are critical. The 0.1870-inch hole diameter recommendation and 0.1130-inch solid height guide installation into typical bores and housings.

Key Features

• Closed and ground ends for stable seating and uniform load transfer
• 0.18-inch outside diameter suits compact bore and housing installations
• 4.5 lb/in spring rate provides predictable, consistent compression force
• 1.5-pound maximum working load rated for light precision-load applications
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Plain silver finish suitable for general indoor mechanical environments

Compatibility

Designed as a precision compression spring for mechanical assemblies requiring a 0.18-inch outside diameter and 0.50-inch free length with closed and ground ends. Confirm bore diameter, housing depth, and required spring rate against your assembly specifications before installation.

Installation Notes

Installation is typically performed by mechanical technicians or trade professionals during assembly or maintenance of equipment containing spring-loaded mechanisms. De-energize and fully depressurize any system before disassembling spring-loaded components. Verify that the mating bore diameter accommodates the 0.1870-inch recommended hole diameter and that the housing depth is sufficient for the free length under no-load conditions. Avoid overstressing the spring beyond the rated maximum working load, as this can cause permanent set and reduce service life.
