With a 0.312 inches outer diameter, 0.156 inches inner diameter, and an overall assembled height of 0.025 inches, this conical washer-style spring generates 13.71 pounds of load at its rated deflection of 0.0413 inches. Constructed from steel, it is suited for applications where high load capacity is needed in a limited space. Installation is typically performed by mechanical assemblers, maintenance technicians, or trade professionals working on fastener preload, valve, or precision hardware assemblies.\u003c\/p\u003e\n\u003cp\u003eThe MB0312-017 fits applications calling for a 5\/32 inch bolt size interface. Belleville disc springs of this size are commonly used in industrial fastener assemblies, electrical contact stacks, valve seats, and precision mechanical sub-assemblies where controlled deflection and repeatable spring force are critical. The small form factor makes it appropriate for tight-tolerance assemblies found in HVAC equipment, pumps, and general mechanical hardware requiring axial load management.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.312 inches outer diameter with 0.156 inches inner diameter for 5\/32 inch bolt size fitment\u003c\/li\u003e\n  \u003cli\u003eOverall assembled height of 0.025 inches suits space-constrained axial applications\u003c\/li\u003e\n  \u003cli\u003eRated load of 13.71 pounds at 0.0413 inches deflection for predictable spring performance\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability under cyclic compressive loads\u003c\/li\u003e\n  \u003cli\u003eSold individually with a package quantity of 12 for stocking convenience\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for assemblies requiring a Belleville disc spring with a 5\/32 inch bolt size interface, 0.312 inches outer diameter, and 0.156 inches inner diameter. Verify load, deflection, and dimensional requirements against your assembly drawings before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBelleville disc springs are installed by mechanical or trade technicians familiar with spring-stack assemblies. Before servicing any assembly, de-energize and relieve all stored mechanical and hydraulic energy. Springs may be stacked in series to increase deflection range or in parallel to increase load capacity  -  confirm the stacking configuration against design specifications. Do not exceed the rated deflection, as over-compression can permanently deform the spring and alter load characteristics.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Assembled Height\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDeflection\u003c\/strong\u003e: 0.0413 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad at Deflection\u003c\/strong\u003e: 13.71 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 5\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\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: MB0312-017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51993902776626,"sku":"MB0312-017","price":24.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7e4ed7a89f685d6961be12ccc19447d.jpg?v=1789991442","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mb0312-017-belleville-disc-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
