Gardner Spring 36581G Precision Compression Spring

Product Description

The GARDNER SPRING 36581G is a precision compression spring manufactured from music wire to AISI 302, ASTM A228, and ASTM A313 standards. It measures 0.72 inches outside diameter with a 2.5-inch free length and a wire diameter of 0.1051 inches. The spring delivers a maximum work load of 95 pounds and a spring rate of 79.75 pounds per inch. End type is closed and ground, which provides a flat, stable seating surface. Machinists, maintenance technicians, and mechanical assemblers install this part in precision mechanical assemblies where consistent load and deflection performance are required.

This compression spring is suited for light-to-medium duty mechanical applications including industrial equipment, tooling fixtures, valves, and general mechanical assemblies. The plain finish and music wire construction make it appropriate for dry or low-moisture indoor environments. Its solid height of 1.279 inches and 0.75-inch hole diameter fit a range of standard spring pockets and guide pins.

Key Features

• Closed and ground ends for flat, stable seating and accurate load transfer
• Music wire construction meeting AISI 302, ASTM A228, and ASTM A313 standards
• 79.75 lb/in spring rate for predictable deflection under load
• 95-pound maximum work load capacity
• Plain silver finish suitable for dry indoor mechanical environments
• Solid height of 1.279 inches limits over-compression in constrained assemblies

Compatibility

Designed for use in standard spring pockets or over guide pins with a hole diameter of 0.75 inches. Suitable as a precision OEM-style compression spring in mechanical assemblies requiring closed and ground ends.

Installation Notes

Installation is typically performed by machinists or mechanical maintenance technicians. De-energize and lockout any equipment before servicing spring assemblies. Verify the spring pocket or guide pin dimensions match the specified outside diameter and hole diameter before installation. Do not compress the spring beyond its solid height during assembly or operation.
