Gardner Spring 36090G Precision Compression Spring

Product Description

The GARDNER SPRING 36090G is a precision compression spring manufactured from music wire with a plain silver finish. It features a 0.48-inch outside diameter and a 0.50-inch free length, making it a compact, high-tolerance spring suited for applications where consistent load response is critical. The 36090G carries a maximum work load of 11.5 pounds and a spring rate of 35 pounds per inch. The closed and ground end type provides flat, stable seating under load. This spring is handled and installed by mechanical maintenance technicians, production engineers, and MRO professionals working with small-component assemblies.

This compression spring is suited for use in light-duty mechanical assemblies, instrumentation, valve mechanisms, and precision equipment where a small-envelope spring with repeatable performance is required. Its compact free length and tight outside diameter make it appropriate for installations where space is constrained and consistent deflection under load is necessary. The 36090G ships in packages of five, supporting both single-unit repair and small-batch production needs.

Key Features

• Closed and ground ends for flat, stable seating and accurate load transfer
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 35 lb/in spring rate for predictable, linear deflection response
• 0.0449-inch wire diameter for high-stress-to-size ratio in a compact footprint
• Plain silver finish with no coating to interfere with tight-tolerance bores
• Solid height of 0.192 inches allows significant working travel within a short free length

Compatibility

Designed as an OEM-style precision compression spring for mechanical assemblies requiring a 0.48-inch outside diameter, 0.50-inch free length, and 0.50-inch hole diameter clearance fit.

Installation Notes

Installation is performed by mechanical technicians or engineers during assembly or component replacement. Ensure the mating bore and pilot dimensions are verified against the 0.50-inch hole diameter and 0.48-inch outside diameter before installation. De-energize or depressurize any system before disassembling spring-loaded components. Do not compress the spring beyond its solid height of 0.192 inches during installation or testing.
