This conical washer-style spring delivers 467.83 pounds of load at its rated deflection of 0.016 inches, making it well suited for bolt preloading, vibration dampening, and precision clamping applications where axial space is limited. Constructed from steel, the MB0312-011 maintains consistent spring force in tight tolerances. It is typically installed by mechanical assemblers, millwrights, and maintenance technicians working with industrial fastening systems, valve assemblies, and precision equipment.\u003c\/p\u003e\u003cp\u003eThis Belleville disc spring is intended for use in assemblies where controlled axial load and compact profile are required. With an outer diameter of 0.312 inches, an inner diameter of 0.156 inches, and an overall assembled height of 0.022 inches, the MB0312-011 fits a 5\/32-inch bolt size. It is commonly used in stacked spring configurations to multiply load capacity or increase deflection range, depending on stack orientation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel construction for durable, repeatable spring performance\u003c\/li\u003e\n\u003cli\u003e467.83 pounds of load at 0.016 inches of deflection\u003c\/li\u003e\n\u003cli\u003e0.312 inches outer diameter, 0.156 inches inner diameter\u003c\/li\u003e\n\u003cli\u003e0.022 inches overall height for use in axially constrained assemblies\u003c\/li\u003e\n\u003cli\u003eFits 5\/32-inch bolt size\u003c\/li\u003e\n\u003cli\u003eAvailable in packages of 12 per the manufacturer minimum order quantity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 5\/32-inch bolt size fastening and clamping assemblies requiring a 0.312-inch OD Belleville disc spring.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eBelleville disc springs are installed by mechanical technicians and assemblers following the equipment manufacturer's stacking specifications. De-energize and relieve all mechanical load from the assembly before disassembly or spring replacement. Stack orientation  -  parallel or series  -  determines whether load or deflection is increased, so confirm the intended configuration before installation. Handle disc springs carefully to avoid edge deformation, which can alter load characteristics.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter (OD)\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter (ID)\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Assembled Height (OAH)\u003c\/strong\u003e: 0.022 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeflection\u003c\/strong\u003e: 0.016 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad at Deflection\u003c\/strong\u003e: 467.83 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\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: MB0312-011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52089001181490,"sku":"MB0312-011","price":27.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad26fb4e4a2fd663fe1b21d8196b5575.jpg?v=1790061456","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mb0312-011-belleville-disc-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
