It features an outside diameter of 0.217 inches and a free length of 0.551 inches, making it a compact, high-tolerance spring suited for precision assemblies. The spring delivers a maximum work load of 6.7 pounds and a spring rate of 4.07 inch-pounds per inch. Closed ends provide stable seating against mating surfaces without additional machining. This part is appropriate for use by mechanical engineers, maintenance technicians, and OEM assemblers working in instrumentation, valve, or electromechanical applications.\u003c\/p\u003e\n\u003cp\u003eThis compression spring fits into precision assemblies where tight dimensional tolerances and consistent load characteristics are required. Its stainless steel construction supports use in environments with exposure to moisture or mild corrosives, common in fluid handling, valve actuation, and light industrial equipment. The compact form factor suits applications in medical devices, electronics hardware, instrumentation panels, and small mechanical assemblies where repeatable spring force is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOutside diameter of 0.217 inches for tight-tolerance bore fits\u003c\/li\u003e\n  \u003cli\u003eFree length of 0.551 inches with a solid height of 0.167 inches\u003c\/li\u003e\n  \u003cli\u003eMaximum work load of 6.7 pounds with a spring rate of 4.07 inch-pounds per inch\u003c\/li\u003e\n  \u003cli\u003eClosed end type for flat, stable seating on contact surfaces\u003c\/li\u003e\n  \u003cli\u003eStainless steel material with plain finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 17223, DIN 17224, and DIN 2095 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision OEM-style compression spring for use in mechanical assemblies requiring an 0.217-inch outside diameter closed-end compression spring with stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanical technicians or OEM assemblers during equipment build or maintenance. Ensure the mating bore or seat is clean and free of debris before seating the spring. Avoid overcompressing the spring beyond its solid height of 0.167 inches, as this can cause permanent set and loss of load characteristics. Verify spring rate and load requirements against the application specification before substituting this part.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Type\u003c\/strong\u003e: Precision Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 6.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 4.07 inch-pounds per inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.217 inches (5.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 0.551 inches (14.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSolid Height\u003c\/strong\u003e: 0.167 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 0.0197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Closed\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\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 17223, DIN 17224, DIN 2095\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161904\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: MC040-0140-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52039170031922,"sku":"MC040-0140-S","price":16.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b072c0b3bf0a6552d36b1fc61473bc1c.jpg?v=1790025979","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mc040-0140-s-compression-spring-0-217in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
