Gardner Spring 36347G Precision Compression Spring

Product Description

The GARDNER SPRING 36347G is a precision compression spring manufactured from AISI 302 music wire with a plain silver finish. It features a 0.3-inch outside diameter, a 1-inch free length, and a 0.022-inch wire diameter. The spring delivers a rated spring rate of 2.8 pounds per inch and a maximum work load of 2 pounds. Closed and ground ends provide stable, even seating under load. This part is suited for mechanical assemblies where repeatable, consistent force characteristics are required in a compact envelope. Machinists, maintenance technicians, and OEM assembly professionals are the typical end users.

This compression spring is used in precision mechanical and light industrial applications where a small-diameter, low-load spring is needed. Typical installations include instrument mechanisms, valve assemblies, light-duty actuators, and small electromechanical devices. The 0.313-inch hole diameter clearance and 0.181-inch solid height make it a practical fit for compact spring pockets in both residential and commercial equipment. Its compliance with AISI 302, ASTM A228, and ASTM A313 standards supports use in applications with documented material requirements.

Key Features

• Closed and ground ends for flat, stable seating and accurate load transfer
• 2.8 pounds per inch spring rate for predictable deflection behavior
• 0.022-inch wire diameter music wire construction per ASTM A228 and ASTM A313
• Compact 0.181-inch solid height suits tight spring-pocket designs
• Plain silver finish on AISI 302 music wire for general-purpose mechanical use
• Meets AISI 302, ASTM A228, and ASTM A313 material standards

Compatibility

Designed as a precision OEM-style compression spring for mechanical assemblies requiring a 0.3-inch outside diameter, 1-inch free length spring with closed and ground ends. Fits spring pockets with a minimum hole diameter of 0.313 inches.

Installation Notes

Installation is performed by qualified mechanical technicians or assemblers working with precision spring-loaded mechanisms. Ensure the mating spring pocket or bore is clean and free of debris before seating the spring. De-energize or depressurize any assembly before removing or replacing compression springs to prevent unexpected release of stored energy. Verify solid height and free length clearances against the housing design before final assembly.
