Gardner Spring 36401G Precision Compression Spring

Product Description

The GARDNER SPRING 36401G is a precision compression spring manufactured from AISI 302 music wire with a plain finish. It features a 0.36 inch outside diameter and a 1.5 inch free length, with a wire diameter of 0.026 inches. The spring delivers a maximum work load of 3.0 pounds and a spring rate of 2.7 pounds per inch, making it suitable for light-duty mechanical assemblies requiring consistent, repeatable force output. Closed and ground ends ensure stable seating and accurate load transfer. This spring is appropriate for use by mechanical technicians, industrial maintenance professionals, and precision assembly workers.

This compression spring is designed for use in precision mechanical applications where controlled deflection and consistent spring rate are required. Typical install scenarios include light-duty actuators, valves, switches, instrumentation components, and small mechanical assemblies across industrial, HVAC, plumbing, and general equipment maintenance applications. Its compact dimensions allow fitment in space-constrained assemblies requiring reliable return force or load-bearing compression behavior.

Key Features

• Closed and ground ends for stable seating and accurate load application
• Spring rate of 2.7 pounds per inch for predictable, linear deflection
• Maximum work load of 3.0 pounds (15.57 N)
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Solid height of 0.239 inches allows use in compact assemblies
• Plain silver finish suitable for general-purpose mechanical environments

Compatibility

Designed to fit assemblies with a hole diameter of 0.375 inches (3/8 inch). Suitable as a precision replacement or OEM-style compression spring in mechanical systems requiring a 0.36 inch OD, 1.5 inch free length spring with closed and ground ends.

Installation Notes

Installation of compression springs should be performed by qualified mechanical or maintenance technicians. Ensure all equipment is de-energized and depressurized before disassembly and spring replacement. Verify that the mating bore or housing diameter accommodates the 0.375 inch hole diameter fitment and that the solid height clearance is confirmed before final assembly. Do not exceed the rated maximum work load during installation or operation.
