The bushing features a 1 inch hole diameter, a 1-7\/8 inch outside diameter, and a 3-1\/8 inch overall length. It holds a total indicator runout (TIR) of 0.0004 inches, providing the close concentricity tolerances that precision milling operations require. Machined from alloy steel for durability under cutting loads, this bushing is a standard consumable stocked and replaced by machinists and toolroom technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis bushing is intended for use with milling machine arbors where the arbor outside diameter needs to be stepped down to accept 1 inch bore tooling. It suits horizontal and vertical milling setups in both production and maintenance machining applications. The 3-1\/8 inch length provides sufficient contact area for stable tool seating along the arbor shank. Weighing 1.12 pounds, the part ships as a single unit and is a direct drop-in for standard arbor configurations requiring this size combination.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch hole diameter for compatibility with 1 inch bore tooling\u003c\/li\u003e\n\u003cli\u003e1-7\/8 inch outside diameter fits corresponding milling machine arbor bores\u003c\/li\u003e\n\u003cli\u003e3-1\/8 inch length provides full engagement along the arbor shank\u003c\/li\u003e\n\u003cli\u003e0.0004 inch TIR runout for precision concentricity in milling operations\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction resists wear and deformation under milling loads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with milling machine arbors, as specified by the manufacturer.

Ensure the milling machine spindle is fully de-energized and the arbor is removed from the machine before fitting or removing the bushing. Inspect the arbor bore and bushing OD for nicks or burrs and clean contact surfaces before assembly to preserve the stated runout tolerance. Follow the machine manufacturer guidelines for drawbar torque and arbor retention hardware.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Indicator Runout (TIR)\u003c\/strong\u003e: 0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Milling Machine Arbors\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: SC08200040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695188836658,"sku":"SC08200040","price":27.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b809802fd99dbafd6dd0a61b5d9a30e8.jpg?v=1788332270","url":"https:\/\/voomisupply.com\/products\/value-collection-sc08200040-arbor-bushing-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
