This conical washer-style spring generates significant clamping or preload force through controlled deflection. With a 1-inch outer diameter, a 0.505-inch inner diameter, and an overall assembled height of 0.071 inches, the MB1000-043 delivers a rated load of 424.89 pounds at its specified deflection of 0.0295 inches. Constructed from steel, it is suited for use in mechanical assemblies, bolted joints, and industrial equipment where consistent spring force is required. Installation is typically performed by mechanical technicians and maintenance professionals.\u003c\/p\u003e\u003cp\u003eThis Belleville disc spring is sized for use with 1\/2-inch bolt applications. It is commonly used in stacked or single configurations within bolted flange assemblies, valve components, electrical equipment, and industrial machinery where space is limited and precise load control is critical. The compact profile allows integration into tight mechanical envelopes while maintaining high load-bearing capacity relative to its size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated load of 424.89 pounds at 0.0295 inches of deflection\u003c\/li\u003e\n\u003cli\u003e1-inch outer diameter with 0.505-inch inner diameter for 1\/2-inch bolt fitment\u003c\/li\u003e\n\u003cli\u003eOverall height of 0.071 inches for low-profile axial installation\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in mechanical load and preload applications\u003c\/li\u003e\n\u003cli\u003eCan be stacked in series or parallel to tune load and deflection characteristics\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSized for use with 1\/2-inch bolts.

Ensure the mating surfaces are clean and free of burrs before seating the spring. When stacking multiple disc springs, verify the orientation  -  series stacking increases deflection while parallel stacking increases load. Always relieve system pressure or mechanical preload before removing or replacing disc springs in a live assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.505 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height (OAH)\u003c\/strong\u003e: 0.071 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeflection\u003c\/strong\u003e: 0.0295 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad at Deflection\u003c\/strong\u003e: 424.89 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: 0.09 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: MB1000-043\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51975905444146,"sku":"MB1000-043","price":25.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c5e47b40f98ca2d2867965366bdec62.jpg?v=1789978403","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mb1000-043-belleville-disc-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
