Gardner Spring 36629G Precision Compression Spring

Product Description

The GARDNER SPRING 36629G is a precision compression spring manufactured from AISI 302 music wire with a plain silver finish. It features a 0.97-inch outside diameter, a 3-inch free length, and a 0.1051-inch wire diameter. Designed for closed and ground ends, this spring delivers a spring rate of 31 lb/in and a maximum working load of 56 pounds. It is suited for applications requiring consistent force and precise dimensional tolerances in mechanical assemblies. Licensed technicians and mechanical maintenance professionals install this component in equipment requiring reliable compression force management.

This compression spring is intended for use in industrial and commercial mechanical assemblies where precise spring force and dimensional accuracy are required. Its closed and ground end configuration provides stable seating and flat load transfer, making it appropriate for pneumatic tools, valve mechanisms, HVAC equipment actuators, and general industrial machinery. The 1-inch hole diameter fitment and 1.17-inch solid height make it compatible with standard bore and housing configurations across a wide range of trade and industrial applications.

Key Features

• Closed and ground ends for stable, flat seating and uniform load distribution
• Spring rate of 31 lb/in for predictable, linear compression response
• Maximum working load of 56 pounds (258.01 N)
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 0.97-inch OD fits a 1-inch hole diameter bore
• Plain silver finish suitable for general-purpose dry and light-duty environments

Compatibility

Designed as an OEM-style precision compression spring for mechanical assemblies requiring a 0.97-inch outside diameter, 3-inch free length, and closed and ground end configuration across industrial and trade equipment applications.

Installation Notes

Installation of this compression spring should be performed by a qualified mechanical or maintenance technician. De-energize and lock out all power sources before accessing any assembly containing this spring. Verify bore diameter, housing depth, and load requirements against the spring specifications before installation. Do not exceed the rated maximum working load of 56 pounds to avoid permanent deformation or premature failure.
