With a 0.937 inch outer diameter, a 0.317 inch inner diameter, and an overall height of 0.06 inches, this conical washer-style spring fits tightly into space-constrained applications where conventional coil springs cannot. It is manufactured from steel and delivers a load of 2.5 pounds at its rated deflection of 0.019 inches. Maintenance technicians, millwrights, and mechanical assemblers working on HVAC equipment, pump assemblies, and industrial fastener stacks routinely install this type of spring to maintain preload under thermal cycling or vibration.\u003c\/p\u003e\u003cp\u003eThis Belleville disc spring is suited for use in residential and light commercial mechanical systems where a 5\/16 inch bolt size is specified. Typical applications include bolt preload retention, valve seating, and vibration dampening in bolted flange and bearing retainer assemblies. Its small form factor makes it appropriate wherever axial space is limited and a precise, repeatable spring force is required. Package quantity is 12 pieces with a minimum order quantity of 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel construction for durability in mechanical and thermal cycling environments\u003c\/li\u003e\n\u003cli\u003e0.937 inch outer diameter fits 5\/16 inch bolt assemblies\u003c\/li\u003e\n\u003cli\u003e2.5 pound load rating at 0.019 inch deflection for predictable preload performance\u003c\/li\u003e\n\u003cli\u003eLow-profile 0.06 inch overall height suits tight axial clearance applications\u003c\/li\u003e\n\u003cli\u003eCan be stacked in series or parallel to tune load and deflection characteristics\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service Belleville disc spring for mechanical assemblies specifying a 5\/16 inch bolt size, a 0.937 inch outer diameter, and a 0.317 inch inner diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eBelleville disc springs are typically installed by millwrights, mechanical assemblers, or HVAC technicians during equipment assembly or scheduled maintenance. De-energize and lock out the equipment before disassembling any fastened joint. Verify spring orientation and stacking configuration against the original equipment drawing, as reversing or inverting the spring alters the load curve. Do not substitute a spring with a different OD, ID, or height without confirming the new load-deflection values meet design requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter (OD)\u003c\/strong\u003e: 0.937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter (ID)\u003c\/strong\u003e: 0.317 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height (OAH)\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeflection\u003c\/strong\u003e: 0.019 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad at Deflection\u003c\/strong\u003e: 2.5 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\/16 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: 0.07 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: MB0937-030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52107128701234,"sku":"MB0937-030","price":61.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c1aee67bc8bdacf311a3af10f3f67f3.jpg?v=1790074035","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mb0937-030-belleville-disc-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
