This hardened fastening component secures bearing positions within the spindle and gear train, maintaining precise axial positioning under the rotational loads typical of a milling head. It is a direct OEM-style replacement part intended for use by qualified machine tool technicians and maintenance professionals servicing BRIDGEPORT milling equipment. Proper bearing retention is critical to spindle accuracy, and this locknut is engineered to meet the original assembly specifications for the applications listed below.\u003c\/p\u003e\n\u003cp\u003eThis locknut bearing is specifically designed for the 2J-Head Back Gear assembly on I Series BRIDGEPORT milling machines. It fits into the back gear section of the 2J-Head, which controls spindle speed range selection. This part is typically replaced during back gear overhauls, spindle rebuilds, or when bearing play or spindle runout is traced to a worn or damaged locknut. Maintenance technicians working on BRIDGEPORT I Series mills will encounter this component during any disassembly of the back gear train.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOEM BRIDGEPORT replacement part for the 2J-Head Back Gear assembly\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for I Series milling machines\u003c\/li\u003e\n  \u003cli\u003eSecures bearing axial position within the spindle and gear train\u003c\/li\u003e\n  \u003cli\u003eDirect fitment replacement — no modification required for listed applications\u003c\/li\u003e\n  \u003cli\u003eSold individually (package quantity of 1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with BRIDGEPORT I Series milling machines equipped with the 2J-Head Back Gear assembly.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machine tool technician or mechanical maintenance professional. Disconnect and lock out all electrical power to the milling machine before disassembling any spindle or gear train components. A bearing locknut spanner wrench of the appropriate size is typically required for removal and installation. Avoid applying impact force directly to the locknut during assembly, as this may damage the bearing seat or thread engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Locknut Bearing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: 2J-Head Back Gear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: I Series Milling Machines\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242100\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: BRIDGEPORT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 11181794\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRIDGEPORT","offers":[{"title":"Default Title","offer_id":51538907988274,"sku":"11181794","price":77.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_207bab65-266a-453a-a8e2-c8309d764e39.jpg?v=1785829243","url":"https:\/\/voomisupply.com\/products\/bridgeport-11181794-locknut-bearing-2j-head-milling-machine","provider":"Voomi Supply","version":"1.0","type":"link"}
