This hardware fastener secures the pinion shaft hub assembly, maintaining proper alignment and retention within the machine's head or knee drive mechanism. Weighing 0.2 pounds, it is a small but critical piece of hardware that machinists and machine tool technicians install during routine maintenance or component rebuilds. Correct fitment and seating of this screw ensures the integrity of the shaft-to-hub connection under operational load.\u003c\/p\u003e\u003cp\u003eThis screw is intended for use with Bridgeport I Series milling machines, classified under accessory type as a pinion shaft hub screw for basic machine configurations. It is typically installed during head disassembly, quill service, or knee-feed rebuilds where the pinion shaft hub must be removed and refastened. Machine shops, tool-and-die facilities, and industrial maintenance teams are the primary end users for this type of replacement hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOEM Bridgeport replacement part for the pinion shaft hub assembly\u003c\/li\u003e\n\u003cli\u003eDesigned for I Series milling machine configurations\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.2 pounds for easy handling during service\u003c\/li\u003e\n\u003cli\u003eSingle-unit packaging supports exact-quantity replacement ordering\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 23242100 for procurement and catalog classification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Bridgeport I Series Milling Machines in basic machine configurations, as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machine tool technician or millwright familiar with Bridgeport milling machine assemblies. Power down and lock out the machine at the main disconnect before disassembling any shaft or hub components. Use the appropriate hand tools and torque practices standard to the machine's service documentation. Do not substitute this fastener with non-OEM hardware, as improper fit can compromise hub retention and machine accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Pinion Shaft Hub Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: Basic Machine\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\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 12190182\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRIDGEPORT","offers":[{"title":"Default Title","offer_id":51544126652722,"sku":"12190182","price":25.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_21d96204-4a25-4c23-a225-1b3f04d5188d.jpg?v=1785924538","url":"https:\/\/voomisupply.com\/products\/bridgeport-12190182-pinion-shaft-hub-screw-milling","provider":"Voomi Supply","version":"1.0","type":"link"}
