Gardner Spring 36077G Precision Compression Spring

Product Description

The GARDNER SPRING 36077G is a precision compression spring manufactured from music wire (AISI 302, ASTM A228, ASTM A313) with a plain silver finish. It features a 0.42-inch outside diameter, a 1.5-inch free length, and a 0.0421-inch wire diameter. The spring rate is 10.5 pounds per inch with a maximum work load of 11 pounds (48.93 N). Closed and ground ends provide consistent seating and accurate load transfer. This spring is suited for mechanical assemblies, light industrial equipment, and trade applications requiring repeatable, calibrated compression force in a compact form factor.

The 36077G fits applications where a small-diameter, moderate-rate compression spring is required. Typical use cases include valve assemblies, actuator returns, tool mechanisms, and electromechanical components in HVAC equipment, plumbing valves, and electrical panel hardware. The closed and ground end configuration makes it appropriate for guided spring installations where perpendicularity and solid-height consistency are critical to correct function.

Key Features

• 0.42-inch outside diameter with 0.4370-inch recommended hole diameter for guided installations
• 1.5-inch free length; 0.4420-inch solid height
• Spring rate of 10.5 pounds per inch for predictable load deflection
• Maximum work load of 11 pounds (48.93 N)
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Closed and ground ends for flat, stable seating surfaces

Compatibility

Designed as a precision compression spring for mechanical assemblies requiring a 0.42-inch OD, 1.5-inch free length, and 10.5 pounds-per-inch spring rate in guided or unguided spring installations.

Installation Notes

Install and service compression springs with all system energy de-energized and mechanical assemblies fully depressurized before disassembly. Use the appropriate spring removal tools to prevent uncontrolled release of stored spring energy. Verify that the spring seating bore or guide post dimensions are compatible with the 0.42-inch OD and 0.4420-inch solid height before final assembly. Inspect mating surfaces for burrs or damage that could affect perpendicular seating.
