With a 1-1\/2 inch inner diameter, a 2-1\/8 inch outer diameter, and a 1-1\/4 inch thickness, this spacer provides consistent, repeatable standoff between cutting tools, collars, and flanges. The hardened and ground finish ensures flat, parallel faces that maintain dimensional accuracy under the clamping forces typical of horizontal and vertical milling operations. Machinists and tool-room technicians rely on precision spacers like this one to build up arbor assemblies without introducing runout or misalignment.\u003c\/p\u003e\n\u003cp\u003eThis arbor spacer is suited for use on milling machine arbors in production and job-shop environments. It is commonly used when building multi-cutter arbor setups, spacing gang mills, or adjusting cutter position on horizontal milling machines. The 1-1\/2 inch bore fits standard milling arbors of that diameter, and the hardened alloy steel construction holds up to the repeated clamping and release cycles of active machine tool service. Tool-room machinists and CNC setup technicians are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHardened and ground alloy steel construction for flat, parallel faces and long service life\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch inner diameter fits standard milling machine arbors\u003c\/li\u003e\n  \u003cli\u003e2-1\/8 inch outer diameter provides adequate bearing surface for cutter collars and flanges\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch thickness for precise axial spacing in multi-cutter arbor assemblies\u003c\/li\u003e\n  \u003cli\u003eWeighs 0.75 pounds for easy handling during arbor assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with milling machine arbors requiring a 1-1\/2 inch bore spacer. Confirm arbor diameter, required spacing thickness, and OD clearance against your machine and tooling specifications before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or qualified tool-room technician should handle arbor assembly and disassembly. Always power down and lock out the machine spindle before installing or removing arbor components. Inspect spacer faces for burrs or contamination before seating, as debris between faces introduces runout. Follow the machine manufacturer's arbor clamping torque procedure and applicable shop safety standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1-1\/4 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\u003eApplication\u003c\/strong\u003e: Milling Machine Arbors\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: SC08183741\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707969962290,"sku":"SC08183741","price":41.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d0fc19539df73aa6259fc20fb99950a.jpg?v=1788443180","url":"https:\/\/voomisupply.com\/products\/value-collection-sc08183741-alloy-steel-arbor-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
