This assembly provides the mechanical components needed to maintain proper variable-speed disc engagement and spring tension within the machine's drive system. The kit includes a collar spring, insert, key, and spring, supplying all the core hardware required for a complete service or replacement of the varidisc assembly. At 5 pounds, the assembly is a direct-fit component suited for milling machine maintenance technicians working on drive train repairs.\u003c\/p\u003e\n\u003cp\u003eThis assembly is intended for use on Bridgeport-type mills, specifically I Series milling machines. It is a common service part in machine shop environments where variable-speed head mechanisms require periodic rebuilding or spring replacement due to wear, fatigue, or damage. Machinists and machine tool service technicians performing preventive maintenance or corrective repairs on the variable-speed drive will find this kit provides all the essential internal components in a single package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eComplete assembly includes collar spring, insert, key, and spring for full service in one kit\u003c\/li\u003e\n  \u003cli\u003eDesigned for Bridgeport-type mill variable-speed drive systems\u003c\/li\u003e\n  \u003cli\u003eCompatible with I Series milling machines\u003c\/li\u003e\n  \u003cli\u003eDirect OEM-style replacement for worn or damaged varidisc spring components\u003c\/li\u003e\n  \u003cli\u003eSold as a single package unit with no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for Bridgeport-type mills and I Series milling machines as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machine tool technician familiar with variable-speed milling machine drive systems. Always disconnect and lock out electrical power to the machine before disassembling the variable-speed head or accessing the varidisc components. Refer to the machine manufacturer's service documentation for proper assembly sequence and component orientation. Incorrect reassembly of the varidisc and spring components can affect drive engagement and machine performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Spring Assembly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: Bridgeport Type Mills\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\u003eIncludes\u003c\/strong\u003e: Collar Spring, Insert, Key, Spring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 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\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: 12550029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRIDGEPORT","offers":[{"title":"Default Title","offer_id":51540236861746,"sku":"12550029","price":1491.38,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2c9d3e8dda5b4d92fba39ff9019409a.jpg?v=1785849782","url":"https:\/\/voomisupply.com\/products\/bridgeport-12550029-varidisc-spring-assembly-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
