Gardner Spring 36365G Precision Compression Spring

Product Description

The GARDNER SPRING 36365G is a precision compression spring manufactured from music wire to AISI 302, ASTM A228, and ASTM A313 standards. It features a 0.3-inch outside diameter, a 1.5-inch free length, and a 0.026-inch wire diameter. The spring rate is 3.5 lb/in with a maximum work load of 4.0 pounds. Closed and ground ends provide stable seating and consistent load transfer across repeated compression cycles. This spring ships in a package quantity of five and is suited for engineers, maintenance mechanics, and trade professionals sourcing precision hardware for mechanical assemblies.

This compression spring is used in light-duty mechanical and industrial applications requiring controlled spring force within a small-diameter envelope. Typical install scenarios include actuator mechanisms, valve assemblies, tooling fixtures, and similar equipment where a consistent spring rate and precise dimensional tolerances are required. The plain silver finish is appropriate for dry or lightly protected environments. Package quantity of five units supports both single-unit replacement and small-batch assembly needs.

Key Features

• Closed and ground end type for flat, stable seating surfaces
• Spring rate of 3.5 lb/in for predictable, linear load response
• Maximum work load of 4.0 pounds (18.91 N)
• Music wire construction meeting AISI 302, ASTM A228, and ASTM A313 standards
• Solid height of 0.301 inches allows compact installation in tight clearances
• Recommended hole diameter of 0.313 inches for guided installation

Compatibility

Designed as a precision replacement or original-equipment compression spring for mechanical assemblies requiring a 0.3-inch OD, 1.5-inch free length, and 3.5 lb/in spring rate with closed and ground ends.

Installation Notes

Installation is typically performed by mechanical technicians or maintenance professionals. Ensure the mating bore or guide rod is sized to the recommended hole diameter of 0.313 inches to prevent lateral deflection and binding. De-energize and lock out any powered equipment before replacing springs in actuated assemblies. Do not compress the spring beyond its solid height of 0.301 inches during installation or operation.
