With a 7\/8 inch inner diameter, a 1-3\/8 inch outer diameter, and a 3\/8 inch thickness, this spacer provides precise, rigid positioning of cutting tools and arbor components. It is manufactured from alloy steel and hardened and ground to ensure dimensional accuracy and resistance to wear under repeated use. Machinists and toolroom professionals rely on spacers like this to maintain correct cutter spacing and axial positioning on horizontal and vertical milling setups.\u003c\/p\u003e\n\u003cp\u003eThis arbor spacer is suited for toolroom, production, and maintenance machining environments where consistent cutter placement is required. It fits standard milling machine arbors with a 7\/8 inch bore. Typical applications include spacing end mills, side milling cutters, and other arbor-mounted tooling on knee mills and horizontal milling machines. The compact dimensions and hardened finish make it appropriate for both light-duty and moderate-production milling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHardened and ground alloy steel construction for dimensional accuracy and wear resistance\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch inner diameter sized for standard milling machine arbors\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch outer diameter provides adequate bearing surface for cutter positioning\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch thickness for precise axial spacing of arbor-mounted tooling\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.09 pounds for easy handling during setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental spacer for milling machine arbors requiring a 7\/8 inch bore and 1-3\/8 inch outer diameter spacer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians during arbor tool setup. Always power down and lock out the milling machine spindle before installing or removing arbor spacers. Ensure the arbor, spacer faces, and cutter bore are clean and free of chips or burrs before assembly. Do not exceed the machine spindle speed rating or the arbor load capacity when using arbor-mounted tooling assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: Hardened and Ground\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Milling Machine Arbors\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SC08180242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717465014578,"sku":"SC08180242","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a16eb3f280ef3d69a9c805a7b703b070.jpg?v=1788540903","url":"https:\/\/voomisupply.com\/products\/value-collection-sc08180242-arbor-spacer-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
