Manufactured from steel, this bushing features a 21\/64 inch inside diameter, a 3\/4 inch body outside diameter, and a 1-3\/8 inch length under head. The head outside diameter measures 1-3\/64 inches with a 1\/4 inch head height. The inside diameter is held to a close tolerance of +0.0001 to +0.0005 inches, ensuring consistent tool guidance and repeatable hole location across production runs. It is compatible with an LS-1 lock screw for secure seating in the liner. Machinists, tool-and-die makers, and fabrication shops rely on this type of component to maintain accuracy in drilling, reaming, and boring operations.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in renewable bushing systems where the slip-fixed configuration allows the bushing to be removed and replaced without disturbing the liner installed in the jig plate. The SF industry code designates it as a standard slip-fixed type with a head. Typical applications include production jigs in metal fabrication, aerospace component drilling fixtures, and general-purpose tooling setups requiring guided hole operations. The steel construction provides the hardness and wear resistance needed for repetitive drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed installation method for use with renewable liner bushings\u003c\/li\u003e\n  \u003cli\u003e21\/64 inch inside diameter with tight tolerance of +0.0001 to +0.0005 inches\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance in high-cycle drilling applications\u003c\/li\u003e\n  \u003cli\u003eLS-1 compatible lock screw secures bushing in position during use\u003c\/li\u003e\n  \u003cli\u003eHeaded design (head OD: 1-3\/64 inches, head height: 1\/4 inch) for positive axial location\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing design allows replacement without liner removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in renewable drill bushing systems accepting SF-series slip-fixed bushings with an LS-1 compatible lock screw.

The mating liner must be properly press-fit into the jig plate before the slip-fixed bushing is inserted. Use the designated LS-1 lock screw to secure the bushing and prevent rotation or axial movement during the drilling operation. Do not force the bushing into an undersized or damaged liner, as this can compromise the inside diameter tolerance and tool guidance accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 21\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-3\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Slip-Fixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: BONEHAM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SF4822IU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51747476111666,"sku":"SF4822IU","price":26.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71c256af6f652c146ccddecf958c3d32.jpg?v=1788880999","url":"https:\/\/voomisupply.com\/products\/boneham-sf4822iu-slip-fixed-drill-bushing-21-64-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
