Gardner Spring 36028G Precision Compression Spring

Product Description

The GARDNER SPRING 36028G is a precision compression spring manufactured from AISI 302 music wire with a plain silver finish. It measures 0.24 inches in outside diameter and 0.625 inches in free length, with a wire diameter of 0.026 inches and a solid height of 0.203 inches. The spring delivers a rated spring rate of 12.5 pounds per inch and a maximum working load of 5.25 pounds. Closed and ground ends provide flat, stable seating surfaces for consistent performance under repeated compression cycles. This part is installed by mechanical assemblers, maintenance technicians, and field service professionals working across a wide range of light-load spring applications.

The 36028G is suited for precision light-duty compression applications in mechanical assemblies, instrumentation, valves, and similar hardware where consistent spring rate and dimensional accuracy are required. Its compact geometry fits into tight bore or housing conditions. The 0.25-inch hole diameter fits a standard guide rod or housing bore, making it a straightforward drop-in component for design and replacement use alike. Sold in a package quantity of five units.

Key Features

• Closed and ground ends for flat seating and accurate load measurement
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Spring rate of 12.5 pounds per inch for predictable, linear deflection
• 0.025-inch hole diameter fits standard guide rod sizing
• Plain silver finish - no coating to affect dimensional tolerances
• Compact solid height of 0.203 inches for space-constrained assemblies

Compatibility

Designed as an OEM-style precision compression spring for light-duty mechanical assemblies requiring a 0.24-inch outside diameter and 0.625-inch free length with a 0.25-inch guide rod or housing bore fit.

Installation Notes

Install by qualified mechanical or maintenance technicians familiar with spring-loaded assemblies. Relieve all preload and de-energize any associated actuator or valve before removing or installing compression springs. Verify that the mating bore or guide rod dimension matches the specified hole diameter and outside diameter before installation. Do not exceed the rated maximum working load of 5.25 pounds to prevent permanent set or premature fatigue.
