Gardner Spring 36503G Precision Compression Spring

Product Description

The GARDNER SPRING 36503G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313). It features a 0.6 inch outside diameter, a 1 inch free length, and a 0.0449 inch wire diameter. The spring rate is 10.5 pounds per inch with a maximum work load of 7 pounds. End type is closed and ground, which provides flat, stable seating surfaces. This component is used across mechanical assemblies, industrial equipment, and trade applications where consistent, repeatable spring force is required. Installation is typically performed by mechanical or maintenance technicians working on sub-assemblies.

This compression spring fits applications requiring a compact, small-diameter spring with controlled deflection characteristics. The closed and ground ends make it suitable for use in precision fixtures, valves, actuators, or mechanical sub-assemblies where accurate load and rate values are critical. The silver plain finish is standard for indoor mechanical environments. With a solid height of 0.226 inches and a recommended hole diameter of 0.625 inches, it integrates cleanly into machined or fabricated housings without modification in most standard designs.

• 10.5 pounds per inch spring rate for consistent, predictable deflection
• Maximum work load of 7 pounds with solid height of 0.226 inches
• 0.6 inch OD fits a recommended 0.625 inch hole diameter for clean housing fit
• Plain silver finish suitable for standard mechanical and industrial environments

Compatibility

Designed as a precision compression spring for mechanical assemblies, valves, actuators, and fixtures requiring a 0.6 inch outside diameter and 1 inch free length with closed and ground ends.

Installation Notes

Compression springs of this type are installed by mechanical or maintenance technicians during assembly or repair of mechanical sub-assemblies. Ensure the mating bore or housing matches the recommended 0.625 inch hole diameter before installation. De-energize or fully de-pressurize any system before removing or replacing springs in pressurized or load-bearing assemblies. Do not compress the spring beyond its solid height of 0.226 inches during installation or operation.
