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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel material provides corrosion resistance for demanding service environments\u003c\/li\u003e\n\u003cli\u003eSpring rate of 4.49 lb\/in for predictable, linear force response across the travel range\u003c\/li\u003e\n\u003cli\u003eMaximum work load of 33.94 lb with an initial tension of 9.8 lb\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 0.73 inches and wire diameter of 0.0915 inches for precise fitment\u003c\/li\u003e\n\u003cli\u003eFree length of 8 inches, maximum extended length of 13.62 inches\u003c\/li\u003e\n\u003cli\u003ePlain finish  -  no coating that could flake or alter dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned 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.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eExtension 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.73 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0915 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 13.62 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 4.49 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 33.94 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial Tension\u003c\/strong\u003e: 9.8 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.29 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GARDNER SPRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: V37C-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51965181690162,"sku":"V37C-SS","price":21.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/beb5bcd9db7346eaf33e1fddbb33b2cf.jpg?v=1789949597","url":"https:\/\/voomisupply.com\/products\/gardner-spring-v37c-ss-extension-spring-0-73in-od-33-94lb","provider":"Voomi Supply","version":"1.0","type":"link"}
