It features a 1.25 inch outer diameter, a 0.63 inch inner diameter, and an overall assembled height (OAH) of 0.111 inches. Constructed from steel, this disc spring delivers 36.19 pounds of load at its rated deflection of 0.0193 inches. Industrial maintenance technicians, mechanical assemblers, and MRO professionals are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis Belleville disc spring is suited for use in bolted joint assemblies requiring controlled spring load, vibration dampening, or thermal expansion compensation. It is sized for 5\/8 inch bolt applications, making it a fit for structural, mechanical, and light industrial fastening work. These springs are commonly stacked in series or parallel to adjust load and deflection characteristics as the application demands.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel construction for durability in mechanical and industrial environments\u003c\/li\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\u003eRated load of 36.19 pounds at 0.0193 inches deflection\u003c\/li\u003e\n\u003cli\u003eLow-profile OAH of 0.111 inches allows use in compact assemblies\u003c\/li\u003e\n\u003cli\u003eCan be stacked in series or parallel to tune load and travel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 5\/8 inch bolt assemblies.

Ensure the mating surfaces are clean and free of burrs before seating the spring. When stacking multiple disc springs, confirm the load-deflection curve matches the assembly specification. Do not exceed the rated deflection to avoid permanent set or spring failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Assembled Height (OAH)\u003c\/strong\u003e: 0.111 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeflection\u003c\/strong\u003e: 0.0193 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad at Deflection\u003c\/strong\u003e: 36.19 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: 0.27 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: MB1250-089\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52088643584306,"sku":"MB1250-089","price":49.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd44443d46e4548ba2ace1e4d5dd52e7.jpg?v=1790061231","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mb1250-089-belleville-disc-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
