It provides rigid, precise positional support for 0.75-inch diameter shafts in linear motion and mechanical drive assemblies. The unit measures 2.75 inches in overall length and 2.13 inches in overall height, with a center height of 1.25 inches. Diameter tolerance is held to plus or minus 0.001 inch, making it suitable for applications that require consistent shaft alignment. This type of component is typically installed by mechanical technicians, millwrights, and industrial maintenance professionals working on motion control, conveyor, or linear actuator systems.\u003c\/p\u003e\n\u003cp\u003eThe SB12 is suited for use in industrial and light commercial mechanical assemblies where plain shafting requires fixed support along a linear axis. It mounts through pre-drilled holes spaced 2 inches center-to-center, using 0.22-inch diameter mounting holes. The malleable iron alloy construction provides durability in environments subject to vibration or moderate mechanical load. This support is a standard catalog component used across a range of linear motion platforms and machine frame assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSupports 0.75-inch diameter plain shafting with tight diameter tolerance of plus or minus 0.001 inch\u003c\/li\u003e\n  \u003cli\u003eMalleable iron alloy construction for durability under vibration and mechanical load\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.75 inches and overall height of 2.13 inches for compact installation footprint\u003c\/li\u003e\n  \u003cli\u003eCenter height of 1.25 inches for consistent shaft centerline positioning\u003c\/li\u003e\n  \u003cli\u003eMounting holes spaced 2 inches center-to-center with 0.22-inch hole diameter for standard fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging with minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit shaft support for plain shafting assemblies requiring a 0.75-inch bore diameter and standard two-hole mounting configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights or mechanical technicians. De-energize and lock out all power to the machine before disassembling any shaft support components. Ensure the mounting surface is flat and clean before securing the support to avoid misalignment. Verify shaft diameter and tolerances against the support bore specification before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 2.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Height\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Diameter Tolerance\u003c\/strong\u003e: -0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Diameter Tolerance\u003c\/strong\u003e: +0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 0.22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter-to-Center Hole Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.625 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: THOMSON INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SB12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMSON INDUSTRIES","offers":[{"title":"Default Title","offer_id":67918665351474,"sku":"SB12","price":112.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da994f6d107485729b74bc8cb536c260_f35cc373-f456-4149-8632-e86475c361ba.jpg?v=1791272071","url":"https:\/\/voomisupply.com\/products\/thomson-industries-sb12-shaft-support-0-75-in-plain-shafting","provider":"Voomi Supply","version":"1.0","type":"link"}
