Gardner Spring 36033G Precision Compression Spring

Product Description

The GARDNER SPRING 36033G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) with a plain silver finish. It features a 0.24-inch outside diameter, a 0.312-inch free length, and a 0.038-inch wire diameter. The spring delivers a rate of 127 pounds per inch with a maximum work load of 16 pounds. Closed and ground ends provide stable, flat seating under load. This spring is suited for mechanical assemblies where consistent force and precise dimensional tolerances are required. Maintenance technicians, machine builders, and OEM assembly operations are the typical end users.

This spring is sized for compact mechanisms and close-tolerance assemblies. Its 0.25-inch hole diameter fit and 0.191-inch solid height make it appropriate for light-duty actuators, valve assemblies, precision instruments, and small electromechanical devices. It is sold in packs of five, which accommodates small batch repairs or replacement stock in a service environment.

Key Features

• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Closed and ground ends for flat, stable seating under compression
• 127 pounds per inch spring rate for consistent, predictable force output
• 16-pound maximum work load capacity
• 0.191-inch solid height supports compact assembly designs
• Plain silver finish - no coating to affect dimensional tolerances

Compatibility

Designed as an OEM-style precision compression spring for light-duty mechanical, electromechanical, and instrumentation assemblies requiring a 0.24-inch outside diameter and 0.312-inch free length spring with a 0.25-inch hole diameter fit.

Installation Notes

Installation is typically performed by mechanical assemblers or maintenance technicians using standard hand tools. Ensure the mating bore or guide pin matches the specified hole diameter of 0.25 inches to prevent buckling or misalignment under load. Verify the assembly does not compress the spring beyond its solid height of 0.191 inches during operation, as doing so can cause permanent set. Follow applicable mechanical assembly standards and equipment manufacturer guidelines for spring replacement procedures.
