Gardner Spring 36111G Precision Compression Spring

Product Description

The GARDNER SPRING 36111G is a precision compression spring manufactured from music wire with a plain silver finish. It measures 0.6 inches in outside diameter and 0.75 inches in free length, with a wire diameter of 0.072 inches. The spring delivers a rated spring rate of 78 lb/in and supports a maximum work load of 30 pounds (133.45 N). Closed and ground ends provide stable seating and consistent load transfer under compression. This part is suited for precision mechanical assemblies where repeatable force and compact dimensions are required. Maintenance technicians, machine builders, and OEM assemblers are the typical end users.

This compression spring is appropriate for use in compact mechanical subassemblies across HVAC equipment, plumbing fixtures, electrical enclosures, and general industrial machinery. Its small form factor and high spring rate relative to its size make it a practical choice for valve mechanisms, actuator returns, and other applications requiring controlled compression force within a tight envelope. The solid height of 0.397 inches sets the compression limit for travel calculations during design or replacement work.

Key Features

• Closed and ground end type for flat, stable seating under load
• Spring rate of 78 lb/in for predictable, linear force response
• Maximum work load of 30 pounds (133.45 N)
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Outside diameter of 0.6 inches fits a hole diameter of 0.625 inches
• Solid height of 0.397 inches defines maximum compression travel

Compatibility

Designed as an OEM-style precision compression spring for mechanical assemblies requiring a 0.6-inch outside diameter and 0.75-inch free length with closed and ground ends.

Installation Notes

Installation is typically performed by mechanical technicians or assemblers working on equipment that has been fully de-energized and depressurized before service. Verify that the mating bore diameter accommodates the 0.625-inch hole diameter specification and that available travel does not exceed the solid height. Do not pre-load the spring beyond the rated maximum work load, as permanent set or fatigue failure may result.
