Gardner Spring 36007G Precision Compression Spring

Product Description

The GARDNER SPRING 36007G is a precision compression spring manufactured from music wire with a plain finish. It measures 0.12 inches in outside diameter and 0.5 inches in free length, making it a compact, high-cycle spring suited for tight assemblies. The spring delivers a rate of 31 pounds per inch and handles a maximum work load of 6 pounds, with a solid height of 0.309 inches. Closed and ground ends provide stable seating and consistent load transfer. Licensed technicians, mechanical assemblers, and maintenance professionals working with small mechanisms and precision equipment install this type of spring.

This spring is designed for use in precision applications where consistent load response and dimensional accuracy are required. Its compact 0.12-inch OD allows installation in bores as small as 0.125 inches. Typical use cases include instrumentation, valve assemblies, electronic hardware, and small mechanical subassemblies found in HVAC controls, plumbing valves, and general industrial equipment. The music wire construction suits applications involving repeated cycling under moderate loads.

Key Features

• Closed and ground ends for stable, flat seating and accurate load measurement
• 31 pounds per inch spring rate for predictable, linear deflection
• 6-pound maximum work load with a solid height of 0.309 inches
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 0.022-inch wire diameter for consistent coil geometry in small-bore applications
• Plain silver finish suitable for dry or lightly lubricated environments

Compatibility

Designed as a precision compression spring for small-bore assemblies requiring a 0.12-inch outside diameter and 0.5-inch free length with a 0.125-inch hole diameter fitment.

Installation Notes

Installation is typically performed by mechanical technicians or assemblers working on small-bore valve, control, or instrumentation hardware. Ensure the bore and seat surfaces are clean and free of burrs before seating the spring. Do not compress the spring beyond its solid height of 0.309 inches during assembly, as this will damage the coils. Follow applicable equipment manufacturer guidelines for preload and assembly torque on surrounding hardware.
