With an outer diameter of 1.5 inches, an inner diameter of 0.755 inches, and an overall assembled height of 0.134 inches, this conical washer-style spring generates 26 pounds of load at its rated deflection of 0.0075 inches. It is suited for applications requiring consistent preload, vibration dampening, or controlled bolt tension in mechanical assemblies. Licensed technicians and mechanical tradespeople working on HVAC equipment, pumps, valves, or industrial fastening systems commonly specify this component.\u003c\/p\u003e\u003cp\u003eThis disc spring is applicable in residential and light commercial mechanical assemblies where space is limited but precise load characteristics are required. It is sized for use with a 3\/4-inch bolt, making it a direct fit in flanged connections, valve stems, shaft assemblies, and similar fastened joints. The stainless steel construction makes it suitable for environments where corrosion resistance is a priority, including wet, chemical-exposure, or outdoor service conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel construction provides corrosion resistance in harsh or wet service environments\u003c\/li\u003e\n\u003cli\u003e1.5 inches outer diameter with 0.755 inches inner diameter sized for 3\/4-inch bolt applications\u003c\/li\u003e\n\u003cli\u003e26 pounds load capacity at 0.0075 inches deflection for predictable spring performance\u003c\/li\u003e\n\u003cli\u003eLow-profile design at 0.134 inches overall height allows tight stack configurations\u003c\/li\u003e\n\u003cli\u003eCan be stacked in series or parallel to adjust load and deflection characteristics\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSized for use with 3\/4-inch bolts. Designed as an OEM-style replacement or aftermarket Belleville disc spring for mechanical assemblies requiring a 1.5-inch OD conical washer spring.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanical technician familiar with spring preload requirements. De-energize and depressurize the assembly before disassembly or spring replacement. When stacking multiple disc springs, confirm series versus parallel orientation against the original equipment specification to achieve the correct load curve. Do not exceed the rated deflection value, as over-compression can permanently deform the spring and compromise load integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.755 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Assembled Height\u003c\/strong\u003e: 0.134 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: 26 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: MB1500-107-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52019505955122,"sku":"MB1500-107-S","price":27.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f5531b0f78fa1d65e9e18cd6d247ebd_282e4068-8438-4f56-93e9-7a2b0e96cca2.jpg?v=1790010984","url":"https:\/\/voomisupply.com\/products\/gardner-spring-mb1500-107-s-belleville-disc-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
