Gardner Spring 36272G Precision Compression Spring

Product Description

The GARDNER SPRING 36272G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) with a plain silver finish. It has an outside diameter of 0.18 inches, a free length of 1.25 inches, and a wire diameter of 0.026 inches. The spring delivers a rated spring rate of 9.7 pounds per inch and supports a maximum work load of 6.0 pounds (30.03 N). Closed and ground ends provide stable seating and consistent load transfer. This spring is suited for applications requiring tight dimensional tolerances and repeatable performance in compact assemblies.

This compression spring is used in light-duty mechanical assemblies across industrial, commercial, and OEM manufacturing applications. Typical installations include instrument mechanisms, valve assemblies, small actuators, latching mechanisms, and precision tooling fixtures. The small outside diameter and short free length make it well-suited for confined spaces where consistent return force is required. Technicians and assembly personnel working in manufacturing, maintenance, and repair environments are the primary end users.

Key Features

• Closed and ground ends for flat, stable seating and accurate load distribution
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Spring rate of 9.7 pounds per inch provides predictable, linear deflection
• Maximum work load of 6.0 pounds suits light-duty precision applications
• Solid height of 0.552 inches allows controlled compression in tight assemblies
• Plain silver finish with no coating that could affect dimensional tolerances

Compatibility

Designed for use in precision mechanical assemblies requiring a compression spring with a 0.18-inch outside diameter and 1.25-inch free length. Compatible with bores up to 0.188 inches in diameter as a hole-fit application.

Installation Notes

Installation is typically performed by mechanical technicians or assembly personnel. Ensure the mating bore or guide pin dimensions are verified against the spring outside diameter of 0.18 inches and hole diameter of 0.188 inches before installation. Compress the spring only within its rated work load range to avoid permanent set. Inspect the seating surfaces to confirm the closed and ground ends are fully supported for accurate load transfer.
