With an outer diameter of 1.25 inches and an inner diameter of 0.63 inches, this conical washer-style spring delivers a rated load of 62.1 pounds at its design deflection of 0.063 inches. The overall assembled height (OAH) measures 0.092 inches. Constructed from steel, it provides consistent spring force under compressive loads. Maintenance technicians, mechanical assemblers, and trade professionals install these springs in bolted joints, valve assemblies, and mechanical connections where controlled preload or vibration damping is required.\u003c\/p\u003e\n\u003cp\u003eBelleville disc springs of this size are commonly used in residential and commercial mechanical systems, including HVAC equipment, plumbing valve assemblies, and electrical panel hardware. The 5\/8-inch bolt size compatibility makes this spring a practical choice for standard fastener stacks where maintaining clamp load over thermal cycling or vibration is critical. It is sold in packages of 12, making it suitable for service kits or multi-point fastener applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.25-inch outer diameter with 0.63-inch inner diameter for 5\/8-inch bolt fitment\u003c\/li\u003e\n  \u003cli\u003e62.1-pound load capacity at rated deflection of 0.063 inches\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under compressive and cyclic loading\u003c\/li\u003e\n  \u003cli\u003eLow-profile design with 0.092-inch overall assembled height\u003c\/li\u003e\n  \u003cli\u003eStackable conical disc format allows load and deflection tuning when used in series or parallel arrangements\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 12 supports multi-fastener service applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/8-inch bolt fastener assemblies.

De-energize and de-pressurize the assembly before disassembly. Stacking orientation affects load and deflection characteristics: springs stacked in the same direction multiply deflection, while opposing stacks multiply load. Refer to applicable mechanical codes and equipment manufacturer specifications for torque and stack configuration requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter (OD)\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter (ID)\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Assembled Height (OAH)\u003c\/strong\u003e: 0.092 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDeflection\u003c\/strong\u003e: 0.063 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLoad at Deflection\u003c\/strong\u003e: 62.1 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\/8 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: 0.2 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: MB1250-062\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51972269932850,"sku":"MB1250-062","price":27.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35d6daf7b195398bf526a0920310be6e.jpg?v=1789965365","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mb1250-062-belleville-disc-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
