With a 7\/8 inch inner diameter, a 1-3\/8 inch outer diameter, and a 1 inch thickness, this spacer provides precise axial positioning of cutters, collars, and other tooling components on arbor setups. The hardened and ground finish ensures tight dimensional tolerances and consistent surface contact, which directly affects cutter runout and tool stability during machining operations. Machinists and toolroom technicians rely on arbor spacers like this one to fine-tune cutter spacing without regrinding or shimming.\u003c\/p\u003e\n\u003cp\u003eThis spacer is intended for use on horizontal and vertical milling machine arbors in job shop, production, and toolroom environments. It is suited to applications where precise cutter positioning is required along the arbor shaft. The 1 inch thickness makes it a standard increment for stacking with other spacers or collars to achieve a target cutter location. Typical users include machinists, tool and die makers, and maintenance technicians working with conventional or CNC milling equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHardened and ground alloy steel construction for consistent dimensional accuracy and surface finish\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch inner diameter fits standard milling machine arbor shafts\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch outer diameter provides adequate bearing surface for cutter and collar contact\u003c\/li\u003e\n  \u003cli\u003e1 inch thickness serves as a standard spacer increment for cutter positioning\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for use with milling machine arbors per UNSPSC Code 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment spacer for milling machine arbors with a 7\/8 inch shaft diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians during arbor setup or cutter changeover. Power down and lock out the milling machine before handling arbor components. Stack spacers and cutters in the intended sequence before tightening the arbor nut, and verify cutter runout with a dial indicator after assembly. Handle hardened ground components carefully to avoid nicking the precision surfaces, which can affect fitment and concentricity.\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 inch\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: 1 inch\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: 0.31 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: SC08180648\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693547028786,"sku":"SC08180648","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/090d576fc404813f1aa769d7df1684cd.jpg?v=1788313955","url":"https:\/\/voomisupply.com\/products\/value-collection-sc08180648-arbor-spacer-7-8-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
