The draw bar is a critical spindle-retention component that secures cutting tool holders and arbors inside the milling machine spindle. Without a properly functioning draw bar, tool holders cannot be clamped securely, creating an unsafe condition and degraded machining accuracy. This assembly is an OEM-sourced replacement part intended for installation by qualified machine tool technicians or millwrights performing preventive maintenance or component replacement on J-Head top housing configurations.\u003c\/p\u003e\n\u003cp\u003eThis draw bar assembly is specifically matched to the J-Head top housing found on Bridgeport I Series milling machines. It is suited for job shop environments, vocational training facilities, and production floors running Bridgeport-style knee mills. Typical installation scenarios include replacing a worn, bent, or stripped draw bar as part of spindle service, or restoring a machine to operational condition after extended use. The assembly ships as a complete unit, reducing the need to source individual hardware components separately.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOEM-matched draw bar assembly for correct thread engagement and spindle fit\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for J-Head top housing configurations\u003c\/li\u003e\n  \u003cli\u003eCompatible with Bridgeport I Series milling machines\u003c\/li\u003e\n  \u003cli\u003eShips as a complete assembly for straightforward replacement\u003c\/li\u003e\n  \u003cli\u003eDirect replacement reduces downtime during spindle service\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 a J-Head top housing.

Power down and lock out the machine at the main disconnect before accessing the spindle or top housing. Do not overtighten the draw bar, as excessive force can damage the spindle taper or tool holder threads. Refer to the machine manufacturer service documentation for proper draw bar engagement procedure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Draw Bar Assembly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: J-Head Top Housing\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\u003eUNSPSC Code\u003c\/strong\u003e: 23242100\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: BRIDGEPORT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12193502\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRIDGEPORT","offers":[{"title":"Default Title","offer_id":51542820749618,"sku":"12193502","price":173.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_182dc3a1-5b3d-432f-bbf3-ecfec86186e7.jpg?v=1785908353","url":"https:\/\/voomisupply.com\/products\/bridgeport-12193502-draw-bar-assembly-j-head-milling-machine","provider":"Voomi Supply","version":"1.0","type":"link"}
