Gardner Spring V37C-SS Extension Spring 0.73in Od 33.94lb

Product Description

The GARDNER SPRING V37C-SS is a stainless steel extension spring engineered for applications requiring reliable tensile force and corrosion resistance. With an outside diameter of 0.73 inches and a wire diameter of 0.0915 inches, this spring delivers a spring rate of 4.49 lb/in and a maximum work load of 33.94 lb. The free body length is 8 inches, extending to a maximum of 13.62 inches under full load. Initial tension is 9.8 lb. This spring is appropriate for industrial, mechanical, and trade-service applications where consistent return force and dimensional stability are required. A licensed mechanic, millwright, or qualified technician typically handles installation in production and service equipment.

This extension spring is suited for use in a range of mechanical assemblies, door hardware, tensioning systems, and equipment requiring controlled return-force over a defined stroke. Its stainless steel construction and plain finish make it a practical choice for environments with exposure to moisture or mild corrosive conditions. The single-piece package supports direct replacement or integration into new mechanical builds where these dimensional and load specifications are matched to the design requirement.

Key Features

• Stainless steel material provides corrosion resistance for demanding service environments
• Spring rate of 4.49 lb/in for predictable, linear force response across the travel range
• Maximum work load of 33.94 lb with an initial tension of 9.8 lb
• Outside diameter of 0.73 inches and wire diameter of 0.0915 inches for precise fitment
• Free length of 8 inches, maximum extended length of 13.62 inches
• Plain finish - no coating that could flake or alter dimensional tolerances

Compatibility

Designed as a direct-specification extension spring for mechanical assemblies requiring a 0.73-inch OD, 8-inch free length, and 4.49 lb/in spring rate in stainless steel construction.

Installation Notes

Extension springs store tensile energy and must be handled with appropriate eye and hand protection during installation and removal. Always de-energize or lock out associated machinery before servicing or replacing springs in mechanical assemblies. Verify that the mounting hooks or end fittings match the spring end configuration before installation. Do not stretch the spring beyond its maximum extended length of 13.62 inches, as permanent deformation or failure can result.
