Gardner Spring 36275G Precision Compression Spring

Product Description

The GARDNER SPRING 36275G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) with a plain silver finish. It measures 0.18 inches outside diameter and 1.5 inches free length, with a wire diameter of 0.026 inches. The spring delivers a rate of 8 pounds per inch and supports a maximum work load of 6 pounds (30.03 newtons). Closed and ground ends provide stable seating and consistent load transfer. This part is suited for mechanical assemblies, instrumentation, and light industrial applications where repeatable spring force and dimensional precision are required. Licensed technicians and mechanical assemblers install this component in production and service settings.

This compression spring fits applications where a small-diameter, light-duty spring is needed in confined spaces. The 0.18-inch outside diameter allows installation into bores up to 0.188 inches. The 0.68-inch solid height defines the compressed limit for proper assembly clearance. Common use cases include control mechanisms, valve assemblies, electronic enclosures, HVAC actuators, and similar precision mechanical systems requiring consistent return force in a compact form factor.

Key Features

• Closed and ground ends for flat, stable seating and accurate load application
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 8 pounds per inch spring rate for predictable, linear force output
• Maximum work load of 6 pounds (30.03 newtons)
• 0.68-inch solid height supports assembly clearance planning
• Plain silver finish suitable for dry and lightly protected environments

Compatibility

Designed as a precision replacement or component spring for mechanical assemblies requiring a 0.18-inch OD compression spring with a 1.5-inch free length and closed, ground ends.

Installation Notes

This spring is typically installed by mechanical assemblers or service technicians during equipment assembly or repair. Before servicing any assembly containing this spring, de-energize and lock out the equipment per applicable safety procedures. Ensure the mating bore diameter does not exceed 0.188 inches and that sufficient clearance exists beyond the 0.68-inch solid height to avoid coil bind. Do not exceed the rated maximum work load of 6 pounds during installation or operation.
