Gardner Spring 36203G Precision Compression Spring

Product Description

The GARDNER SPRING 36203G is a precision compression spring manufactured from AISI 302 music wire with a plain silver finish. It features an outside diameter of 0.12 inches, a free length of 1 inch, and a wire diameter of 0.016 inches. The spring delivers a maximum work load of 2 pounds and a spring rate of 4 pounds per inch, making it well suited for light-duty mechanical assemblies requiring consistent, repeatable force. Closed and ground ends provide stable seating and uniform load distribution across the coil stack. Solid height is 0.375 inches. This part is typically installed by mechanical assemblers, maintenance technicians, and precision equipment specialists working on small-format mechanisms.

The GARDNER SPRING 36203G fits applications requiring a compact compression spring with tight dimensional tolerances. Its 0.125-inch hole diameter fit and 0.12-inch outside diameter make it appropriate for small mechanical assemblies, instrumentation, valve mechanisms, and light-duty industrial equipment where a low-profile spring with a controlled spring rate is required. The music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards, confirming consistent material quality for precision applications.

Key Features

• Outside diameter of 0.12 inches with closed and ground ends for stable, flat seating
• Spring rate of 4 pounds per inch for predictable, linear force response
• Maximum work load of 2 pounds (11.12 N)
• Wire diameter of 0.016 inches for fine-pitch coil construction
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Plain silver finish suitable for a wide range of indoor mechanical environments

Compatibility

Designed as a precision compression spring replacement for small mechanical assemblies requiring a 0.12-inch outside diameter, 1-inch free length, and 4 pounds-per-inch spring rate with closed and ground ends.

Installation Notes

Installation is performed by mechanical technicians or assemblers working on small-format equipment. Ensure the mating bore or pin diameter is verified against the 0.125-inch hole diameter fit and 0.12-inch outside diameter before installation. Do not compress the spring beyond its solid height of 0.375 inches during service. Inspect seating surfaces for burrs or misalignment that could cause off-axis loading and premature fatigue.
