Machined from steel and hardened to 60 to 65 HRC, it delivers the wear resistance required for repeated production drilling operations. The bushing carries an inside diameter of 0.316 inches, a body outside diameter of 0.500 inches, and a length under head of 0.375 inches. A head outside diameter of 0.797 inches and a head height of 0.250 inches seat the bushing securely against the jig plate. It accepts an LS-1 compatible lock screw and meets ANSI standards for slip-fixed bushing dimensions.\u003c\/p\u003e\n\u003cp\u003eSlip-fixed bushings of the SF series are used in drill jigs where a fixed liner bushing is already installed in the plate. The SF326IO drops into the liner, is rotated to lock, and can be removed and replaced without disturbing the jig plate itself. This configuration suits production environments where multiple operations share a single jig plate, or where bushing wear requires periodic changeout. Machinists, tool-and-die makers, and manufacturing maintenance technicians install this component on CNC and manual drill presses, jig borers, and multi-spindle drilling fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInside diameter of 0.316 inches with a tight tolerance of plus 0.0001 to plus 0.0005 inches for accurate tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life in high-cycle drilling applications\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows bushing replacement without removing or re-machining the jig plate liner\u003c\/li\u003e\n  \u003cli\u003eLS-1 compatible lock screw interface secures the bushing in the liner during operation\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI slip-fixed bushing standards for dimensional interchangeability\u003c\/li\u003e\n  \u003cli\u003eHeaded design with 0.797 inch head OD and 0.250 inch head height for positive seating on the jig plate surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard SF-series slip-fixed bushing for use with compatible fixed liner bushings accepting a 0.500 inch body OD.

Ensure the mating liner bushing is clean and free of chips before inserting the SF326IO. Align the bushing head notch with the lock screw, press the bushing into the liner, and rotate to the locked position before securing with the LS-1 lock screw. Power down all spindles and verify the fixture is fully de-energized before performing any bushing changeout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.316 inches (Letter O)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 0.797 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.250 inches\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\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\u003eStandards\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\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: SF326IO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51745487225138,"sku":"SF326IO","price":21.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_8e6c88d4-e65b-4e21-b1b5-79528e6c3919.jpg?v=1788864285","url":"https:\/\/voomisupply.com\/products\/boneham-sf326io-slip-fixed-drill-bushing-0-316-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
