Gardner Spring 36578G Precision Compression Spring

Product Description

The GARDNER SPRING 36578G is a precision compression spring manufactured from music wire and finished plain with a silver appearance. It measures 0.72 inches in outside diameter with a free length of 2.0 inches and a wire diameter of 0.1051 inches. The spring delivers a rate of 102.03 pounds per inch and supports a maximum work load of 97 pounds. End type is closed and ground, which provides flat, stable seating surfaces for consistent load distribution. This part is installed by mechanical technicians, maintenance professionals, and trade contractors in applications requiring controlled compression resistance.

This compression spring is suited for use in residential and light commercial mechanical assemblies where a compact, high-rate spring is required. The closed and ground ends allow it to seat reliably in bores up to 0.75 inches in diameter. Its music wire construction and compliance with established material standards make it appropriate for general-purpose compression applications across HVAC, plumbing, and industrial equipment assemblies.

Key Features

• Closed and ground ends for flat, stable seating and consistent load transfer
• 102.03 lb/in spring rate for predictable, linear compression performance
• 97-pound maximum work load capacity
• Music wire construction per AISI 302, ASTM A228, and ASTM A313 standards
• 0.1051-inch wire diameter with 1.047-inch solid height
• Fits bores up to 0.75 inches in diameter

Compatibility

Designed as an OEM-style precision compression spring for mechanical assemblies requiring a 0.72-inch OD, 2.0-inch free length spring in applications compatible with music wire and plain finish construction.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians familiar with spring-loaded assemblies. Relieve all tension, pressure, or stored energy from the assembly before removing or installing the spring. Confirm bore diameter, free length, and spring rate match application requirements before installation. Avoid compressing the spring beyond its solid height of 1.047 inches to prevent set and premature failure.
