With a 7\/8 inch inner diameter and a 1-3\/8 inch outer diameter, this spacer measures 1-1\/4 inches thick and provides precise axial positioning of cutting tools on arbor setups. The hardened and ground construction ensures tight dimensional tolerances and resistance to wear under the repetitive loading typical of milling operations. Machinist and tool room technicians install this type of spacer to adjust cutter position or fill gaps along a milling arbor without affecting the concentricity of the spindle assembly.\u003c\/p\u003e\n\u003cp\u003eThis arbor spacer is suited for milling machine applications in production shops, tool rooms, and maintenance environments. It is used wherever consistent cutter spacing is required along a horizontal or vertical milling arbor. The alloy steel construction and hardened finish make it appropriate for environments where spacers are repeatedly removed and reinstalled without significant wear or dimensional change. Typical applications include gang milling setups and multi-cutter arbor configurations in both manual and CNC milling machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction with hardened and ground finish for tight dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch inner diameter fits standard milling machine arbor shanks\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch outer diameter provides adequate bearing surface for cutter support\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch thickness for precise axial cutter positioning on the arbor\u003c\/li\u003e\n  \u003cli\u003eHardened surface resists wear during repeated installation and removal cycles\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 requiring a 7\/8 inch bore diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tool room technicians. Before servicing or changing arbor tooling, power down the milling machine and confirm the spindle has come to a complete stop. Inspect the arbor bore and spacer surfaces for burrs or contamination before assembly, as debris can affect concentricity. Follow the machine manufacturer's arbor assembly sequence and torque draw-bar fasteners per the equipment manual specifications.\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1-1\/4 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: 0.3 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: SC08180747\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723981160754,"sku":"SC08180747","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/078d32da2e6968da332eec2903ef22ef.jpg?v=1788611023","url":"https:\/\/voomisupply.com\/products\/value-collection-sc08180747-arbor-spacer-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
