The gear shaft is a critical drivetrain element in the vertical knee-mill assembly, transmitting rotational force along the Z-axis to control vertical table movement. Worn or damaged gear shafts cause imprecise quill or knee travel, backlash, and loss of repeatable depth control. This part restores accurate vertical-axis motion to the machine. Installation requires a qualified machine tool technician or maintenance machinist familiar with Bridgeport-style knee-mill assemblies.\u003c\/p\u003e\n\u003cp\u003eThis gear shaft is used in Bridgeport-style vertical knee milling machines where Z-axis vertical travel is driven through a geared shaft mechanism. Typical service scenarios include rebuild projects, preventive maintenance overhauls, and field repairs caused by wear, corrosion, or mechanical failure in the Z-axis drivetrain. The component is sold individually, making it suitable for targeted part replacement without purchasing a full assembly kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect OEM-style replacement for the Z-axis gear shaft position in Bridgeport milling machine assemblies\u003c\/li\u003e\n  \u003cli\u003eRestores accurate vertical-axis travel and eliminates excessive backlash caused by a worn shaft\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit, allowing targeted replacement without full assembly purchase\u003c\/li\u003e\n  \u003cli\u003eDesigned for integration into the vertical knee-mill Z-axis drivetrain\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement gear shaft for Bridgeport vertical knee milling machines.

De-energize the machine and lock out all power sources following LOTO procedures before disassembling any drivetrain components. Proper removal of the Z-axis assembly typically requires standard machine shop hand tools and a clean work surface to avoid contaminating bearing surfaces. Refer to the applicable Bridgeport service manual for disassembly sequence and reassembly torque references specific to your machine model.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComponent Type\u003c\/strong\u003e: Z-Axis Gear Shaft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Vertical Knee Milling Machine\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: 12060147\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRIDGEPORT","offers":[{"title":"Default Title","offer_id":51543439507762,"sku":"12060147","price":1296.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_911691a4-532b-4c14-b03f-760a467b9acc.jpg?v=1785918619","url":"https:\/\/voomisupply.com\/products\/bridgeport-12060147-z-axis-gear-shaft-milling-machine-part","provider":"Voomi Supply","version":"1.0","type":"link"}
