This style of disc spring  -  also called a Belleville washer  -  stores and releases energy under compressive load, making it essential in bolted joints, valve assemblies, and mechanical preload applications. The MU500-0180 has an outer diameter of 0.98 inches, an inner diameter of 0.525 inches, and an overall assembled height of 0.131 inches. It is rated to carry 11,724.9 pounds of load at its rated deflection of 0.04 inches. Mechanical assemblers, millwrights, and maintenance technicians working in industrial and OEM fastener applications are the typical installers.\u003c\/p\u003e\u003cp\u003eThis curved disc spring is suited for applications requiring consistent axial force in tight spaces where a standard coil spring will not fit. Typical uses include flange bolt load retention, vibration damping stacks, clutch assemblies, and precision preload systems. The 1\/2 inch bolt size compatibility makes it a natural fit for standard fastener assemblies in industrial equipment, pumps, valves, and structural connections. It can be stacked in series to increase deflection or in parallel to increase load, giving engineers and technicians flexibility for a wide range of load and travel requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh load rating of 11,724.9 pounds at 0.04 inches deflection in a sub-1-inch diameter package\u003c\/li\u003e\n\u003cli\u003eOuter diameter of 0.98 inches with inner diameter of 0.525 inches for 1\/2 inch bolt compatibility\u003c\/li\u003e\n\u003cli\u003eOverall height of 0.131 inches allows use in space-constrained assemblies\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability under repeated compressive cycling\u003c\/li\u003e\n\u003cli\u003eStackable in series or parallel configurations to tune load and deflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSized for use with 1\/2 inch bolts.

Always de-energize or depressurize the host assembly before disassembling fastener stacks or valve components. Verify stacking orientation  -  curved disc springs must be oriented correctly relative to load direction to achieve rated performance. Consult the equipment OEM documentation and applicable industry standards for torque and preload requirements specific to the host assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.98 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.525 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeflection\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad at Deflection\u003c\/strong\u003e: 11,724.9 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: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: MU500-0180\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51988652949810,"sku":"MU500-0180","price":28.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08d3ca9f419cc26d06b5f5ad7e99cb79.jpg?v=1789987698","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mu500-0180-curved-disc-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
