Built to ANSI standards, this SF-series bushing features a 0.277 inch (Letter J) inside diameter, a 1\/2 inch body outside diameter, and a 3\/8 inch length under the head. Constructed from steel and hardened to 60 to 65 HRC, it delivers the wear resistance required for high-cycle production drilling. The head-style configuration seats securely in the jig plate while the renewable design allows for in-field replacement without scrapping the entire fixture setup.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for production and toolroom environments where repeatable hole location is critical. It installs into a prepared jig plate bore and is held in position with an LS-1 compatible lock screw, preventing rotation and axial movement during operation. Typical users include tool-and-die makers, machinist toolroom technicians, and fixture builders working in metal fabrication, aerospace, and general manufacturing settings. The SF designation indicates a slip-fixed bushing per ANSI jig bushing standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life in high-cycle drilling\u003c\/li\u003e\n\u003cli\u003e0.277 inch (Letter J) inside diameter with a tight tolerance of +0.0001 to +0.0005 inches\u003c\/li\u003e\n\u003cli\u003e1\/2 inch body outside diameter and 3\/8 inch length under head for compact fixture integration\u003c\/li\u003e\n\u003cli\u003eHead-style design with 51\/64 inch head outside diameter and 1\/4 inch head height\u003c\/li\u003e\n\u003cli\u003eRenewable bushing construction allows replacement without replacing the jig plate liner\u003c\/li\u003e\n\u003cli\u003eLS-1 compatible lock screw interface secures the bushing against rotation and pullout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an ANSI SF-series slip-fixed drill bushing; compatible with LS-1 lock screws.

The jig plate must be bored and reamed to the correct liner or press-fit specification prior to installing an SF-series bushing. Ensure the mating lock screw is an LS-1 compatible type and is fully seated before operating the fixture. De-energize all machine power and secure the workpiece fixture before removing or replacing a worn bushing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Series\u003c\/strong\u003e: SF (Slip-Fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.2770 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: J\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: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 51\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Head (not headless)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRenewable\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\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SF326HU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51729688133938,"sku":"SF326HU","price":20.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_732fedd0-1c23-45a8-87f2-455d86599d5e.jpg?v=1788707812","url":"https:\/\/voomisupply.com\/products\/boneham-sf326hu-slip-fixed-drill-bushing-0-277-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
