With a 0.5000 inch inside diameter and a 1.5000 inch outside diameter, this bushing provides accurate tool guidance and repeatable positioning in machined components. The 2.5000 inch length under head gives adequate depth for stable seating in thick fixture applications. Weighing 1.14 pounds, it is machined to close tolerances suitable for production and maintenance shop environments. Licensed machinists and toolroom technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in rotary tool holder fixtures where a Type J configuration is required. It fits applications calling for a 7\/8 inch hole diameter in the fixture plate. The 1-1\/8 inch distance between hole centers and a D dimension of 11\/16 inch allow it to be positioned correctly alongside adjacent bushings or locating features. It is suited for both production machining environments and job shop tooling builds where precise drill or reamer guidance is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType J bushing configuration for rotary tool holder applications\u003c\/li\u003e\n  \u003cli\u003e0.5000 inch inside diameter for consistent tool guidance\u003c\/li\u003e\n  \u003cli\u003e1.5000 inch outside diameter with 0.2650 inch head thickness for secure seating\u003c\/li\u003e\n  \u003cli\u003e2.5000 inch length under head for deep fixture installations\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch hole diameter fits standard fixture plate bores\u003c\/li\u003e\n  \u003cli\u003e1-1\/8 inch distance between hole centers for accurate multi-bushing layouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for rotary tool holder fixture setups requiring a Type J bushing with a 0.5000 inch inside diameter and a 1.5000 inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Ensure the fixture plate bore is clean and dimensionally verified to the 7\/8 inch hole diameter before pressing or seating the bushing. Power down and lock out any associated machinery before installing or replacing bushings in a live fixture. Do not force the bushing into an undersized bore, as this may alter the inside diameter and compromise tool guidance accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 0.2650 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDistance Between Hole Centers\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eD Dimension\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.14 pounds\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: GLOBAL CNC INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8603J .500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GLOBAL CNC INDUSTRIES","offers":[{"title":"Default Title","offer_id":67910856048946,"sku":"8603J .500","price":109.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4dd3ad51a399321c7178ed9c937993d.jpg?v=1791200755","url":"https:\/\/voomisupply.com\/products\/global-cnc-industries-8603j-500-tool-holder-bushing-type-j","provider":"Voomi Supply","version":"1.0","type":"link"}
