This spring type generates significant axial force within a very small installed height, making it well suited for fastener preloading, vibration dampening, and precision clamping tasks. Constructed from steel, the MU250-0145 measures 0.551 inches outer diameter and 0.265 inches inner diameter, with an overall assembled height (OAH) of 0.06 inches. At its rated deflection of 0.0075 inches, it delivers a load of 4357.7 pounds. Mechanical assemblers, maintenance technicians, and precision equipment service professionals typically specify and install this component.\u003c\/p\u003e\n\u003cp\u003eCurved disc springs of this profile are used across a broad range of industrial, HVAC, and mechanical equipment applications where consistent spring force must be maintained under bolt or shaft preload. The 1\/4 inch bolt size compatibility makes this spring a practical choice for fastener stack assemblies in pumps, compressors, valves, and similar equipment. The small footprint and high load capacity allow engineers and technicians to manage clamp force in tight spaces where coil or wave springs are not practical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh load output of 4357.7 pounds at 0.0075 inches deflection in a compact form factor\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in mechanical preload and clamping applications\u003c\/li\u003e\n  \u003cli\u003e0.551 inches outer diameter fits standard 1\/4 inch bolt assemblies\u003c\/li\u003e\n  \u003cli\u003e0.265 inches inner diameter clears 1\/4 inch fastener shanks cleanly\u003c\/li\u003e\n  \u003cli\u003eLow profile 0.06 inches OAH allows stacking in space-constrained assemblies\u003c\/li\u003e\n  \u003cli\u003eAvailable in packages of 10 for service stock and small-batch installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with 1\/4 inch bolt size fastener assemblies.

De-energize or de-pressurize the assembly completely before disassembling fastener stacks that use disc springs. Standard hand tools and calibrated torque equipment are typically required; do not exceed the fastener torque values specified by the equipment manufacturer. Stacking multiple disc springs in series or parallel will alter deflection and load characteristics and should be calculated prior to assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter (OD)\u003c\/strong\u003e: 0.551 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter (ID)\u003c\/strong\u003e: 0.265 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Assembled Height (OAH)\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDeflection\u003c\/strong\u003e: 0.0075 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad at Deflection\u003c\/strong\u003e: 4357.7 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\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: MU250-0145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52035051258162,"sku":"MU250-0145","price":20.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b6664cb2104124fa8604f66011da278_9a127eca-e647-4cbf-80f2-2ca8b015522b.jpg?v=1790022821","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mu250-0145-curved-disc-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
