Gardner Spring 36125G Precision Compression Spring

Product Description

The GARDNER SPRING 36125G is a precision compression spring manufactured from music wire with a plain silver finish. It features a 0.72-inch outside diameter and a 2-inch free length, making it a compact, high-tolerance component suited for mechanical assemblies requiring consistent load performance. The spring delivers a maximum work load of 25 pounds and a spring rate of 20 pounds per inch. Closed and ground ends provide stable seating and even load distribution. Mechanical engineers, maintenance technicians, and OEM assembly professionals install this type of spring in industrial, HVAC, and equipment applications where repeatable compression force is critical.

This precision compression spring is well suited for use in mechanical controls, valve assemblies, actuator mechanisms, and industrial equipment where a small-diameter, moderate-load spring is required. The 0.75-inch hole diameter fit and 0.686-inch solid height make it appropriate for compact housings with limited axial space. It is sold in a package quantity of 5 with a minimum order quantity of 1 package, making it practical for both service replacement and small production runs.

Key Features

• 0.72-inch outside diameter with 0.072-inch wire diameter for precise dimensional control
• 20 pounds per inch spring rate delivers consistent, predictable compression force
• 25-pound maximum work load rated under standard test conditions
• Closed and ground ends provide flat, stable seating surfaces
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Plain silver finish suitable for dry or lightly lubricated operating environments

Compatibility

Designed as an OEM-style precision compression spring for mechanical assemblies requiring a 0.72-inch outside diameter, 2-inch free length component with closed and ground ends. Verify hole diameter clearance of 0.75 inches and solid height of 0.686 inches against your application before installation.

Installation Notes

Installation of compression springs should be performed by qualified mechanical or maintenance technicians familiar with spring-loaded assemblies. Relieve all system pressure and de-energize any associated electrical or pneumatic components before disassembly. Ensure the mating bore and seat surfaces are clean and free of burrs to prevent uneven loading or premature fatigue. Do not compress the spring beyond its solid height during installation or testing.
