Arbor shims are thin precision spacers used to reduce physical disturbances, correct axial runout, and achieve precise positioning on rotating shafts, arbors, and spindles. This set covers a wide range of thicknesses in a single pack, making it a practical kit for machinists, maintenance technicians, and fabricators who need on-hand shimming stock across multiple tolerance levels. The inside diameter measures 1\/4 inch and the outside diameter measures 3\/8 inch, fitting standard 1\/4 inch arbors and shafts.\u003c\/p\u003e\u003cp\u003eThis shim set is suited for machine shop environments, industrial maintenance, and precision mechanical assembly. It is commonly used when mounting saw blades, grinding wheels, cutters, or other tooling on arbors where fine axial adjustment is required. The 19 included thicknesses allow technicians to mix and stack shims to achieve a specific target spacing without needing to source individual shims. Both light fabrication shops and heavy industrial maintenance programs benefit from having an assorted set at the bench.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e19 shims per pack spanning 0.001 inch through 0.125 inch in graduated thicknesses\u003c\/li\u003e\n\u003cli\u003eLow carbon, full hard steel construction for consistent thickness and durability under load\u003c\/li\u003e\n\u003cli\u003e1\/4 inch inside diameter fits standard 1\/4 inch arbors and shafts\u003c\/li\u003e\n\u003cli\u003e3\/8 inch outside diameter provides adequate bearing surface for small-arbor applications\u003c\/li\u003e\n\u003cli\u003eAssorted thickness range allows stacking to hit precise target dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on 1\/4 inch arbors, spindles, and shafts in machine tool and industrial maintenance applications where low carbon steel shim material is acceptable.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eArbor shims should be installed by qualified machinists or maintenance technicians familiar with rotating tooling and shaft assembly. Always de-energize and lock out the machine before installing or removing shims from any spindle or arbor. Shims may be stacked to achieve a desired combined thickness; ensure all mating surfaces are clean and free of burrs before assembly. Verify final runout with a dial indicator after installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Low Carbon, Full Hard Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Thicknesses\u003c\/strong\u003e: 0.001 in, 0.0015 in, 0.002 in, 0.003 in, 0.004 in, 0.005 in, 0.006 in, 0.007 in, 0.008 in, 0.010 in, 0.012 in, 0.015 in, 0.020 in, 0.025 in, 0.031 in, 0.047 in, 0.062 in, 0.093 in, 0.125 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 19 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION BRAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 25100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION BRAND","offers":[{"title":"Default Title","offer_id":51523405709618,"sku":"25100","price":21.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4f10e4b41f155108ee69a17a5f5fbe0.jpg?v=1785441971","url":"https:\/\/voomisupply.com\/products\/precision-brand-25100-arbor-shim-set-1-4-in-id-3-8-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
