With an outer diameter of 0.875 inches, an inner diameter of 0.442 inches, and an overall height of 0.059 inches, this spring generates a load of 308.3 pounds at its rated deflection range of 0.032 to 0.045 inches. Constructed from steel, it provides consistent spring force in applications where space is limited and precise clamping or preload force is required. Maintenance technicians, mechanical assemblers, and trade professionals working with bolted assemblies or precision fastening systems are the typical installers.\u003c\/p\u003e\u003cp\u003eThis Belleville disc spring is suited for use in bolted flange connections, valve assemblies, bearing preload applications, and electrical or mechanical equipment requiring controlled axial force. Its 7\/16-inch bolt size compatibility makes it a practical fit for standard fastener configurations across industrial, HVAC, plumbing, and electrical equipment assemblies. The spring can be stacked in series to increase deflection or in parallel to increase load, depending on application requirements. It is sold in packages of 12 with a minimum order quantity of 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh load capacity of 308.3 pounds within a deflection range of 0.032 to 0.045 inches\u003c\/li\u003e\n\u003cli\u003eCompact 0.875 inches outer diameter suits tight installation spaces\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability under repeated loading cycles\u003c\/li\u003e\n\u003cli\u003eCompatible with 7\/16-inch bolt size fastener configurations\u003c\/li\u003e\n\u003cli\u003eStackable in series or parallel arrangements to tune load and deflection\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 12 for bench stock or service kit use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 7\/16-inch bolt size fastener assemblies.

Always de-energize or depressurize the assembly before servicing components. Confirm the correct stacking orientation, series versus parallel, to achieve the intended load and deflection per the assembly specification. Do not exceed the rated deflection range, as flattening the spring past its design limit will permanently reduce load performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter (OD)\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter (ID)\u003c\/strong\u003e: 0.442 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height (OAH)\u003c\/strong\u003e: 0.059 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeflection Range\u003c\/strong\u003e: 0.032 to 0.045 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad at Deflection\u003c\/strong\u003e: 308.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Bolt Size\u003c\/strong\u003e: 7\/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: 0.06 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: MB0875-031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52092825502002,"sku":"MB0875-031","price":23.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0a6b4a9dd69e614310b0645cc0b894c.jpg?v=1790064138","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mb0875-031-belleville-disc-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
