This bushing features a 1 inch inside diameter, a 3 inch outside diameter, and a 4.5 inch length under the head, making it suitable for applications that require rigid, concentric tool support. The head thickness measures 0.365 inches, providing a stable shoulder for seating in the holder. Weighing 2.464 pounds, this is a substantial, solid bushing intended for professional machine shop environments. Licensed machinists and toolroom technicians are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eType J tool holder bushings are commonly used in CNC machining centers, knee mills, and drill presses where a standardized bushing is needed to adapt tooling to a specific spindle or holder bore. The 2 inch distance between hole centers accommodates standard mounting configurations found in production and job-shop machining setups. This bushing is appropriate for both light-production and precision one-off machining work where concentricity and rigidity are critical to tool performance and workpiece accuracy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType J bushing configuration for standardized tooling compatibility\u003c\/li\u003e\n\u003cli\u003e1 inch inside diameter and 3 inch outside diameter for defined bore and fit specifications\u003c\/li\u003e\n\u003cli\u003e4.5 inch length under head for deep-reach or extended tooling setups\u003c\/li\u003e\n\u003cli\u003e0.365 inch head thickness provides a positive seating shoulder\u003c\/li\u003e\n\u003cli\u003e2 inch distance between hole centers for standard mounting layouts\u003c\/li\u003e\n\u003cli\u003eWeighs 2.464 pounds, indicating solid, heavy-duty construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Type J rotary tool holder bushing for use in drill presses, knee mills, and CNC machining centers that accept Type J bushing configurations with a 3 inch outside diameter and 1 inch inside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Before installing or removing any tool holder bushing, power down the machine and confirm the spindle has fully stopped. Ensure the bore and bushing mating surfaces are clean and free of chips or burrs before pressing or seating the bushing. Verify that the bushing is fully seated and the head is flush against the holder face before resuming machine operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3 inches (3.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 0.365 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistance Between Hole Centers\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.464 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: 27112809\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SC84949528\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713215758642,"sku":"SC84949528","price":63.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0fd96cdc5a006de80285b099039cdc14.jpg?v=1788492025","url":"https:\/\/voomisupply.com\/products\/value-collection-sc84949528-tool-holder-bushing-type-j","provider":"Voomi Supply","version":"1.0","type":"link"}
