Gardner Spring 36055G Precision Compression Spring

Product Description

The GARDNER SPRING 36055G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) for consistent, repeatable performance in demanding applications. The spring measures 0.3 inches outside diameter with a free length of 0.812 inches and a wire diameter of 0.0449 inches. It delivers a spring rate of 51 pounds per inch and supports a maximum work load of 19.75 pounds. The closed and ground end type ensures stable seating and even load distribution. Machinists, maintenance technicians, and OEM assembly operations use this spring where tight dimensional tolerances are required.

This spring suits a wide range of light-duty mechanical applications including valve assemblies, precision instruments, small pneumatic components, and OEM equipment builds. The plain silver finish and music wire construction make it appropriate for indoor or controlled-environment use where corrosion exposure is limited. It is sold in packages of five, making it practical for bench stock, repair kits, or low-volume production runs.

Key Features

• Closed and ground ends for flat, stable seating and accurate load transfer
• 51 lb/in spring rate for predictable deflection under load
• 19.75 lb maximum work load capacity
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 0.3 inch outside diameter fits holes up to 0.312 inches
• Solid height of 0.417 inches limits over-compression travel

Compatibility

Designed as a precision OEM-style replacement or stock compression spring for mechanical assemblies requiring a 0.3 inch outside diameter, 0.812 inch free length, and closed ground ends in music wire construction.

Installation Notes

Installation is typically performed by machinists, mechanical assemblers, or maintenance technicians. Always verify that the mating bore or housing diameter accommodates the 0.312 inch hole diameter clearance before assembly. Confirm the solid height of 0.417 inches does not allow over-compression beyond the design travel of the surrounding assembly. Wear appropriate eye protection when handling or seating compression springs under load.
