Gardner Spring 36290G Precision Compression Spring

Product Description

The GARDNER SPRING 36290G is a precision compression spring manufactured from music wire with a plain finish. It features a 0.24-inch outside diameter, a free length of 0.313 inches, and a wire diameter of 0.022 inches. The spring delivers a maximum work load of 3.0 pounds and a spring rate of 14.13 pounds per inch. Closed and ground ends provide stable seating and consistent load transfer. This spring is suited for applications requiring tight dimensional tolerances and repeatable performance in compact mechanical assemblies. Licensed technicians and mechanical engineers specify this type of spring in instrumentation, valves, and small-bore actuator mechanisms.

The 36290G fits applications where a small-diameter, high-precision compression spring is required. Its 0.25-inch hole diameter fit makes it compatible with standard small-bore guide pins and housings. Typical use cases include HVAC actuators, plumbing valve cartridges, electrical relay mechanisms, and light-duty industrial assemblies. The music wire construction suits moderate-temperature environments with non-corrosive media. This spring is sold in packages of 5 with a minimum order quantity of 1 package.

Key Features

• Closed and ground ends for flat, stable seating and accurate load application
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Spring rate of 14.13 pounds per inch for predictable, linear deflection behavior
• Maximum work load rated at 3.0 pounds
• Silver plain finish - no coating buildup that could affect dimensional fit
• Solid height of 0.097 inches supports high-deflection, compact-space installations

Compatibility

Designed as an OEM-style precision compression spring for use in small-bore guide applications requiring a 0.25-inch hole diameter fit and a 0.24-inch outside diameter.

Installation Notes

Installation is typically performed by mechanical technicians or licensed trade professionals during valve, actuator, or relay assembly and service. Relieve all system pressure and de-energize any associated electrical circuits before disassembling the host component. Verify that the spring seats fully against mating surfaces before reassembly to ensure consistent load performance. Do not compress the spring beyond its solid height of 0.097 inches during installation.
